Pinpoint Test C: Cannot Change Suspension Modes Using the Ride Control Switch

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 41 , Vehicle Dynamic Suspension for schematic and connector information.

Normal Operation and Fault Conditions

When the ride control switch is pressed, a signal is sent to the PCM. The PCM interprets this signal and sends a message to the IPC over the HS-CAN . When the IPC receives this message, it sends a ride control mode change request message to the VDM over the HS-CAN . The VDM then adjusts the PWM voltage sent to the solenoids to adjust the suspension to the requested setting. A short to ground, voltage or an open in the ride control switch circuits between the PCM and the switch causes the switch to not function. A communication error between any of the 3 modules causes suspension mode change request concerns and also causes the VDM to set DTCs.

Possible Causes

Wiring, terminals or connectors
Ride control switch
PCM

Pinpoint Test G: U0155:87

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 41 , Vehicle Dynamic Suspension for schematic and connector information.

Normal Operation and Fault Conditions

With the ignition ON, the IPC sends the VDM messages over the HS-CAN . If the VDM does not receive these messages within a certain time frame, the module sets DTCs. For information on the messages sent to the VDM by the IPC , refer to the Network Message Chart in Vehicle Dynamic Suspension .

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
U0155:87	Lost Communication With IPC : Missing Message	This DTC sets in continuous memory if the damper mode change request message is missing.

Possible Causes

PINPOINT TEST G: U0155:87

Test Step	Result / Action to Take
G1 CHECK THE COMMUNICATION NETWORK
Ignition ON. Using a scan tool, carry out the network test. Does the IPC pass the network test?	Yes GO to G2 . No REFER to Section 418-01 to diagnose the IPC does not respond to the scan tool.
G2 CHECK THE VDM CMDTCs
Enter the following diagnostic mode on the scan tool: Self Test — VDM . Clear the DTCs. Ignition OFF. Ignition ON. Enter the following diagnostic mode on the scan tool: Self Test — VDM . Record the VDM DTCs. Is DTC U0155:87 retrieved again?	Yes GO to G3 . No The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.
G3 REVIEW THE RECORDED DTCS FROM THE VDM SELF-TEST
Check the recorded DTCs from the VDM self-test. Is DTC U3003:16 or U3003:17 present?	Yes For DTC U3003:16, GO to Pinpoint Test A . For DTC U3003:17, GO to Pinpoint Test B . No GO to G4 .
G4 CHECK FOR DTCS IN THE IPC
Enter the following diagnostic mode on the scan tool: Self Test — IPC . Is DTC U3003:16 or U3003:17 present?	Yes REFER to Section 413-01 . No GO to G5 .
G5 CHECK FOR DTC U0155:XX SET IN OTHER MODULES
Enter the following diagnostic mode on the scan tool: Self Test — All CMDTCs . Is DTC U0155:xx set in 1 or more modules in addition to the VDM ?	Yes CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no TSBs address this concern, INSTALL a new IPC . REFER to Section 413-01 . No CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no TSBs address this concern, INSTALL a new VDM .
