Airbag and Safety Belt Pretensioner Supplemental Restraint System (SRS)

 

Principles of Operation

The Restraints Control Module (RCM) continuously receives/monitors all inputs from the following Supplemental Restraint System (SRS) components:

If the RCM detects sudden vehicle deceleration and/or lateral deceleration based on the information received from all sensors and switches and determines that deployment is required, the RCM sends voltage and current to deploy the appropriate SRS components.

During a frontal or side crash, the RCM may deploy the following SRS components, based on crash severity and sensor input.

The fact that the safety belt retractor pretensioner(s) or air bags did not activate for both front seat occupants in a crash does not mean that something is wrong with the system.

The RCM performs a self-test of the complete SRS during each startup. If a SRS fault exists, the air bag warning indicator will illuminate and remain illuminated for the rest of the ignition cycle. In addition to the self-test at start up, the RCM continuously monitors all of its SRS components and circuitry for correct operation.

Air Bag Warning Indicator

The air bag warning indicator:

Air Bag Module Second Stage Deployment Check

Because the driver and passenger front air bags each have 2 deployment stages, it is possible that Stage 1 has deployed and Stage 2 has not.

If a front air bag module has deployed, it is mandatory that the front air bag module be remotely deployed using the appropriate air bag disposal procedure.

Clockspring

The clockspring:

Driver Air Bag Module

The driver air bag module:

Event Notification Signal

In the event of a crash, the RCM provides an event notification signal to the fuel pump driver module(s) to disable the fuel system.

The RCM does not monitor the event notification signal circuit for faults and will not set a DTC if a fault occurs.

 

High Speed Controller Area Network (HS-CAN)

This vehicle utilizes a communication system called a High Speed Controller Area Network (HS-CAN). The RCM communicates with various modules for required information about the vehicle. Refer to Section 418-00 for information about the HS-CAN .

 

Impact Sensor

The SRS uses 3 satellite sensors in addition to the RCM . The RCM is mounted to the center tunnel beneath the console. The front impact severity sensor (frontal restraint sensor) is located in the front of the vehicle, behind the grille, mounted on the radiator support. The side impact sensors are mounted in each of the doors, behind the trim panel. Mounting orientation is critical for correct operation of all impact sensors.

 

Occupant Classification System (OCS)

The Occupant Classification System (OCS) is found only on the front passenger seat. The front passenger seat OCS is comprised of a silicone gel-filled bladder mounted between the seat cushion foam and pan. An integrated OCSM with pressure sensor is attached to the bladder by a flexible hose. The integrated OCSM with pressure sensor is mounted to the seat frame. Pressure is applied to the OCS bladder when weight of any occupant or object in the front passenger seat is present. The pressure is then transferred through a tube and is sensed by the OCS pressure sensor. The OCSM communicates front passenger classification information to the RCM via the HS-CAN . The RCM uses this information when determining if the passenger air bag module is to be deployed in the event of a deployable crash. The RCM also uses this information for Passenger Air Bag Deactivation (PAD) indicator illumination strategy.

The OCSM monitors the OCS for faults.

The OCS is also used for operation of the passenger Belt Minder®. For information on the passenger Belt Minder® feature, refer to Section 501-20A . To deactivate or reactivate the passenger Belt Minder® feature, refer to Section 413-01 or the Owner's Literature.

 

Belt Tension Sensor (BTS)

The Belt Tension Sensor (BTS):

The BTS is used by the OCS to identify the presence of a child safety seat on the front passenger seat. The BTS senses the tension on the safety belt assembly then provides an output to the OCSM , indicating that the safety belt assembly is cinched. After sensing the weight applied to the seat by the occupant and using the BTS input, the OCSM determines how the occupant should be classified and communicates the information to the RCM . If the occupant is classified as a child, the RCM then automatically deactivates the passenger air bag module and illuminates the PAD indicator.

Passenger Air Bag Deactivation (PAD) Indicator

The Restraints Control Module (RCM) controls the state of the Passenger Air Bag Deactivation (PAD) indicator through a direct hard-wire connection, based on information provided by the OCS system. An exemption to this is when the front passenger seat is determined to be empty, and therefore indication of a deactivated passenger air bag module is not necessary. In all other cases, the PAD indicator is off when the passenger air bag module is enabled.

When the ignition is ON, the RCM briefly activates the PAD indicator to prove out the indicator function and verify to the front occupants correct functional operation of the PAD indicator.

The following table indicates the passenger air bag status and the PAD indicator status based on the size of the front passenger occupant.



 Passenger Air Bag and Passenger Air Bag Deactivation (PAD) Indicator Status

Small Buckled/ Unbuckled Disabled Lit
Large Buckled/ Unbuckled Enabled Unlit

 

Passenger Air Bag Module

The passenger air bag module:

 

Restraints Control Module (RCM)

 WARNING: If a vehicle has been in a crash, inspect the restraints control module (RCM) and the impact sensor (if equipped) mounting areas for deformation. If damaged, restore the mounting areas to the original production configuration. A new RCM and sensors must be installed whether or not the airbags have deployed. Failure to follow these instructions may result in serious personal injury or death in a crash.

NOTE: Carrying out Programmable Module Installation (PMI) will not enable the 911 assist option that is disabled.

The RCM carries out the following functions:

The RCM monitors the SRS for possible faults. If a fault is detected, the RCM will request the IPC to illuminate the air bag warning indicator. When the ignition is turned OFF and then ON, the IPC will prove out the air bag warning indicator by lighting for 6 seconds. If no faults are detected by the RCM , the IPC will turn the air bag warning indicator off and it will remain off. If the RCM detects a fault, it will send a message to the IPC to turn the air bag warning indicator on and it will remain on for the rest of the ignition cycle. If the RCM requests illumination of the air bag warning indicator and the air bag warning indicator does not function, the IPC will automatically activate an audible chime. The chime is a series of 5 sets of 5 tone bursts. If the chime is heard, the SRS and the air bag warning indicator require repair.

The RCM includes a backup power supply. This feature provides sufficient backup power to deploy the air bags in the event that the ignition circuit is lost or damaged during impact. The backup power supply will deplete its stored energy approximately one minute after power and/or ground has been removed from the RCM .

 

Safety Belt Buckle Switches

The safety belt buckles are comprised of integrated circuits called Hall-effect switches. The safety belt buckle switches indicate to the RCM whether the safety belts are buckled or unbuckled.

The RCM supplies current to the safety belt buckle switch. Current flows through the switch, buckled or unbuckled to ground. The RCM will sense the difference in this current draw, approximately 6 mA (unbuckled) or 15 mA (buckled), and use this information in determining the deployment rate of the dual-stage driver and passenger air bag modules. If the RCM detects current out of this range, it will set a DTC.

The RCM also communicates the driver safety belt buckle switch status to the IPC , which monitors the information to control the safety belt warning indicator. For information on the safety belt warning indicator, refer to Section 413-01 .

 

Safety Belt Retractor Pretensioner

Safety belt retractor pretensioners are pyrotechnic devices integrated to the safety belt retractor assemblies. Safety belt retractor pretensioners control the tension of the driver and passenger safety belts in the event of a deployable crash.

 

Seat Track Position Sensors

The seat track position sensors are comprised of integrated circuits called Hall-effect switches. The seat track position sensors indicate to the RCM the position of the driver and passenger seat. The RCM uses this information in determining the deployment rate of the dual-stage air bag modules.

 

Secondary Air Bag Warning (Chime)

The secondary air bag warning chime is an audible chime located in and controlled by the IPC . If a fault is detected with the air bag warning indicator, a DTC will be stored in memory of the IPC . Upon receiving the message from the RCM that a SRS fault has been detected, the IPC will sound the secondary air bag warning chime in a pattern of 5 sets of 5 beeps.

 

Seat Side Air Bag Module

The side air bag module is mounted in the seat backrest and will deploy upon receiving a flow of current from the RCM .

 

Fault PIDs

There are 2 types of fault PIDs that can be reported by the OCSM . The first type, considered conventional, has only one level of fault reporting and identifies a specific concern for a given component and points to a particular diagnostic path, example: DTC B1317 (Battery Voltage High).

The second type uses a process within the software of the controller that maps the byte and bit to name a specific device and fault condition. This process is called bit-mapping and is referred to as fault PIDs in the diagnosis of the vehicle. This type does not identify the specific concern or component on the first level of fault reporting, example: DTC B2909 ( BTS Fault). DTC B2909 can have up to 3 specific on-demand fault PIDs (areas of concern) associated with this DTC.

Those associated fault PIDs are an extension of the information provided by the DTC and are identified by the same DTC number. A scan tool must be used to view DTCs and their fault PIDs. Once a scan tool has retrieved a DTC, use the scan tool to view the fault PIDs. In the diagnostic path, other types of PIDs are sometimes used to determine the root cause (example: resistance or voltage PIDs).

When viewing fault PIDs, the scan tool can display the PIDs associated with that DTC, including the status or state that exists (on-demand [active] DTC) or existed (continuous memory [historic] DTC). Refer to the manufacturer instructions for the scan tool being used on how to view fault PIDs.

NOTE: Do not mistake status information displayed with DTCs for fault PID information. Fault PIDs are only retrieved in the DataLogger function of the scan tool.

While the RCM does not utilize fault PIDs for this vehicle, the OCSM has fault PIDs for certain faults.

 

Prove Out Procedure

Turn ignition from OFF to the ON position and monitor the air bag warning indicator with all SRS components connected. The IPC will illuminate the air bag warning indicator continuously for approximately 6 seconds and then turn off. If a SRS fault is present, the air bag warning indicator will:

The air bag warning indicator may not illuminate to indicate a fault is present until approximately 30 seconds after the ignition has been turned from the OFF to the ON position. This is the time required for the RCM to complete the testing of the SRS . If the air bag warning indicator is inoperative and a SRS fault is detected, a chime will sound in a pattern of 5 sets of 5 beeps. If this occurs, the air bag warning indicator will need to be repaired before diagnosis can continue.

 

Inspection and Verification

  1. Verify the customer concern by checking the air bag warning indicator in the IPC . Refer to Prove Out the System in this section.
  1. Visually inspect for obvious signs of mechanical or electrical damage. Do not disconnect electrical connectors until directed to do so within the pinpoint test.

Pinpoint Test A: The Air Bag Warning Indicator is Illuminated Continuously

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

During normal operation, the Instrument Panel Cluster (IPC) module will illuminate the air bag indicator continuously for 6 seconds. If the Supplemental Restraint System (SRS) is fault free, the air bag warning indicator will turn off and remain off. If a fault is detected in the SRS , the air bag warning indicator will illuminate and remain illuminated for the rest of the ignition cycle until the fault is no longer detected. The Restraints Control Module (RCM) will communicate to the IPC via the High Speed Controller Area Network (HS-CAN). The IPC will illuminate the air bag indicator based on messaging from the RCM or if there is no communication between the RCM and IPC .

 
PINPOINT TEST A: THE AIR BAG WARNING INDICATOR IS ILLUMINATED CONTINUOUSLY

 WARNING: Always tighten the fasteners of the restraints control module (RCM) and impact sensor (if equipped) to the specified torque. Failure to do so may result in incorrect restraint system operation, which increases the risk of personal injury or death in a crash.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Test Step Result / Action to Take
  A1 RETRIEVE RCM DTCs  
  • Ignition ON.
  • Enter the following diagnostic mode on the scan tool: Self Test — RCM .
  • Were any DTCs retrieved on-demand during self-test?
Yes
GO to the DTC Charts in this section for diagnostic direction.

Do not clear any DTCs until all DTCs have been resolved.

No
If the RCM does communicate with the scan tool, REFER to Section 413-01 to diagnose the IPC concern.

Do not clear any DTCs until all DTCs have been resolved.
 

Pinpoint Test B: DTCs B0001:11, B0001:12, B0001:13 and B0001:1A

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The Restraints Control Module (RCM) continuously monitors the driver air bag module stage 1 and circuits for the following faults:

If a fault is detected, the RCM will store DTC B0001:11, B0001:12, B0001:13 or B0001:1A in memory and send a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at time of diagnosis. Following this direction will help make sure that minor changes in resistance do not create a repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
  • B0001:11 — Driver Frontal Stage 1 Deployment Control: Circuit Short to Ground
When the RCM senses a short to ground on either driver air bag stage 1 circuit, a fault will be indicated.
  • B0001:12 — Driver Frontal Stage 1 Deployment Control: Circuit Short to Battery
When the RCM senses a short to voltage on either driver air bag stage 1 circuit, a fault will be indicated.
  • B0001:13 — Driver Frontal Stage 1 Deployment Control: Circuit Open
When the RCM measures greater than the desired resistance range between driver air bag stage 1 circuits, a fault will be indicated.
  • B0001:1A — Driver Frontal Stage 1 Deployment Control: Circuit Resistance Below Threshold
When the RCM measures less than the desired resistance range between driver air bag stage 1 circuits, a fault will be indicated.

 
PINPOINT TEST B: DTCs B0001:11, B0001:12, B0001:13 AND B0001:1A

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Supplemental Restraint System (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

Pinpoint Test D: DTCs B0010:11, B0010:12, B0010:13 and B0010:1A

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The Restraints Control Module (RCM) continuously monitors the passenger air bag module stage 1 and circuits for the following faults:

If a fault is detected, the RCM will store DTC B0010:11, B0010:12, B0010:13 or B0010:1A in memory and send a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at time of diagnosis. Following this direction will help make sure that minor changes in resistance do not create a repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
  • B0010:11 — Passenger Frontal Stage 1 Deployment Control: Circuit Short to Ground
When the RCM senses a short to ground on either passenger air bag stage 1 circuit, a fault will be indicated.
  • B0010:12 — Passenger Frontal Stage 1 Deployment Control: Circuit Short to Battery
When the RCM senses a short to voltage on either passenger air bag stage 1 circuit, a fault will be indicated.
  • B0010:13 — Passenger Frontal Stage 1 Deployment Control: Circuit Open
When the RCM measures greater than the desired resistance range between passenger air bag stage 1 circuits, a fault will be indicated.
  • B0010:1A — Passenger Frontal Stage 1 Deployment Control: Circuit Resistance Below Threshold
When the RCM measures less than the desired resistance range between passenger air bag stage 1 circuits, a fault will be indicated.

 
PINPOINT TEST D: DTCs B0010:11, B0010:12, B0010:13 AND B0010:1A

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Supplemental Restraint System (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test E: DTCs B0011:11, B0011:12, B0011:13 and B0011:1A

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The Restraints Control Module (RCM) continuously monitors the passenger air bag module and stage 2 circuits for the following faults:

If a fault is detected, the RCM will store DTC B0011:11, B0011:12, B0011:13 or B0011:1A in memory and send a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at time of diagnosis. Following this direction will help make sure that minor changes in resistance do not create a repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
  • B0011:11 — Passenger Frontal Stage 2 Deployment Control: Circuit Short to Ground
When the RCM senses a short to ground on either passenger air bag stage 2 circuit, a fault will be indicated.
  • B0011:12 — Passenger Frontal Stage 2 Deployment Control: Circuit Short to Battery
When the RCM senses a short to voltage on either passenger air bag stage 2 circuit, a fault will be indicated.
  • B0011:13 — Passenger Frontal Stage 2 Deployment Control: Circuit Open
When the RCM measures greater than the desired resistance range between passenger air bag stage 2 circuits, a fault will be indicated.
  • B0011:1A — Passenger Frontal Stage 2 Deployment Control: Circuit Resistance Below Threshold
When the RCM measures less than the desired resistance range between passenger air bag stage 2 circuits, a fault will be indicated.

 
PINPOINT TEST E: DTCs B0011:11, B0011:12, B0011:13 AND B0011:1A

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Supplemental Restraint System (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test G: DTCs B0028:11, B0028:12, B0028:13 and B0028:1A

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The Restraints Control Module (RCM) continuously monitors the passenger seat side air module and bag circuits for the following faults:

If a fault is detected, the RCM will store DTC B0028:11, B0028:12, B0028:13 or B0028:1A in memory and send a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at time of diagnosis. Following this direction will help make sure that minor changes in resistance do not create a repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
  • B0028:11 — Right Side Airbag Deployment Control: Circuit Short to Ground
When the RCM senses a short to ground on either passenger seat side air bag circuit, a fault will be indicated.
  • B0028:12 — Right Side Airbag Deployment Control: Circuit Short to Battery
When the RCM senses a short to voltage on either passenger seat side air bag circuit, a fault will be indicated.
  • B0028:13 — Right Side Airbag Deployment Control: Circuit Open
When the RCM measures greater than the desired resistance range between the passenger seat side air bag circuits, a fault will be indicated.
  • B0028:1A — Right Side Airbag Deployment Control: Circuit Resistance Below Threshold
When the RCM measures less than the desired resistance range between the passenger seat side air bag circuits, a fault will be indicated.

 
PINPOINT TEST G: DTCs B0028:11, B0028:12, B0028:13 AND B0028:1A

 WARNING: Never disassemble or tamper with seat belt deployable components, including pretensioners, load limiters and inflators. Never back probe deployable device electrical connectors. Tampering or back probing may cause an accidental deployment and result in personal injury or death.

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Supplemental Restraint System (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

Pinpoint Test P: DTCs B1211:11, B1211:12, B1211:13 and B1211:1A

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The Restraints Control Module (RCM) continuously monitors driver safety belt retractor pretensioner and circuits for the following faults:

If a fault is detected, the RCM will set and store DTC B1211:11, B1211:12, B1211:13 or B1211:1A in memory and send a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at time of diagnosis. Following this direction will help make sure that minor changes in resistance do not create a repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
  • B1211:11 — Driver Seatbelt Retractor Pretensioner Deployment Control: Circuit Short to Ground
When the RCM senses a short to ground on either driver safety belt retractor pretensioner circuit, a fault will be indicated.
  • B1211:12 — Driver Seatbelt Retractor Pretensioner Deployment Control: Short to Battery
When the RCM senses a short to battery on either driver safety belt retractor pretensioner circuit, a fault will be indicated.
  • B1211:13 — Driver Seatbelt Retractor Pretensioner Deployment Control: Circuit Open
When the RCM measures greater than the desired resistance range between the driver safety belt retractor pretensioner circuits, a fault will be indicated.
  • B1211:1A — Driver Seatbelt Retractor Pretensioner Deployment Control: Circuit Resistance Below Threshold
When the RCM measures less than the desired resistance range between the driver safety belt retractor pretensioner circuits, a fault will be indicated.

 
PINPOINT TEST P: DTCs B1211:11, B1211:12, B1211:13 AND B1211:1A

 WARNING: Never disassemble or tamper with seat belt deployable components, including pretensioners, load limiters and inflators. Never back probe deployable device electrical connectors. Tampering or back probing may cause an accidental deployment and result in personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Supplemental Restraint System (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Normal Operation

The Restraints Control Module (RCM) monitors all deployable device and sensor circuits for a signal cross coupled (short) between circuits. If the RCM detects a short between the circuits of one device and another device, it will store a DTC for each of the signal cross coupled faults in memory. The RCM sends a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator. When a normal loop fault is present (one loop is either shorted to battery/ground, open circuit or low resistance), then signal cross coupled diagnostics will not be active. Once the normal loop fault is repaired, then the signal cross coupled diagnostics will resume.

Pinpoint Test Y: DTC B2909

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The Belt Tension Sensor (BTS) operates in conjunction with the Occupant Classification System (OCS). The OCS interprets a variable voltage signal provided by the BTS to identify the possible presence of a child safety seat in the front passenger seat. The voltage output of the BTS is proportional to the amount of tension applied to the sensor by the belt, no-tension low voltage (approximately 0.95 volt), high-tension high voltage (approximately 3.8 volts).

The Occupant Classification System Module (OCSM) monitors the BTS and all circuitry for faults. If a fault is detected, the OCSM stores DTC B2909 in memory and sends a message to the Restraints Control Module (RCM). The RCM then sets DTC B00A0:68 and sends a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.

NOTE: Do not mistake status information displayed with DTCs for fault PID information. Fault PIDs are only retrieved in the DataLogger function of the scan tool.

PINPOINT TEST Y: DTC B2909

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

 WARNING: Never disassemble or tamper with seat belt deployable components, including pretensioners, load limiters and inflators. Never back probe deployable device electrical connectors. Tampering or back probing may cause an accidental deployment and result in personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Supplemental Restraint System (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
