Principles of Operation

NOTE: The luggage compartment lid must be closed for correct operation of the video camera system.

NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

The rear video camera system is used to assist the driver while reversing or parking the vehicle. For vehicles without navigation, the image of the area behind the vehicle is displayed in the LH side of the auto-dimming interior mirror. For vehicles with navigation, the image of the area behind the vehicle is displayed in the Front Display Interface Module (FDIM). A dashed line on the displayed image represents the center of the vehicle and 3 color-coded lines (red, yellow, green) identify different zones between the rear of the vehicle and objects located behind the vehicle.

NOTE: The color-coded lines may not indicate accurate or consistent distances between objects located behind the vehicle and the rear of the vehicle. This normal condition is due to variances in vehicle ride height, including, but not limited to, vehicle loading. The color coded lines and center line, if available, can appear to be off center or misaligned from the target. This is due to the placement of the video camera being off centered to the rear of the vehicle. The lines are designed to guide the driver to the correct target even if they appeared not centered.

For vehicles without navigation, the signal from the rear video camera is sent to the auto-dimming interior mirror display on a pair of shielded video circuits. For vehicles with navigation, the signal from the rear video camera is sent to the FDIM on a pair of shielded video circuits. The displayed video image is horizontally inverted from that viewed from the video camera perspective to mimic a conventional mirror image. The rear video camera system is active with the ignition in RUN and the transmission selector in the REVERSE (R) position.

For vehicles without navigation, the system remains active for approximately 3 seconds after the transmission selector is moved from the REVERSE (R) position. The rear video camera system cannot be disabled during these conditions.

For vehicles with navigation, the video system has a delay feature that keeps the image displayed on the FDIM until the vehicle reaches 8 km/h (5 mph) and the vehicle is shifted out of REVERSE (R). The operator has the ability to turn the delay feature on or off with the on screen options in the FDIM . The image is not displayed if the vehicle is shifted into PARK (P).

Inspection and Verification

1. Verify the customer concern.

2. Visually inspect for obvious signs of mechanical and electrical damage.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

4. NOTE: Make sure to use the latest scan tool software release.

   If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).

5. NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM .

   If the scan tool still does not communicate with the VCM :
   • Check the VCM connection to the vehicle.
   • Check the scan tool connection to the VCM .
   • Refer to Section 418-00 , No Power To The Scan Tool, to diagnose no power to the scan tool.

6. If the scan tool does not communicate with the vehicle:
   • Verify the ignition key is in the RUN position.
   • Verify the scan tool operation with a known good vehicle.
   • Refer to Section 418-00 to diagnose no response from the PCM.

7. Carry out the network test.
   • If the scan tool responds with no communication for one or more modules, refer to Section 418-00 .
   • If the network passes, retrieve and record the continuous memory DTCs.

8. Clear the continuous DTCs and carry out the self-test diagnostics for the ACM .

9. If the DTCs retrieved are related to the concern, go to DTC Charts. For all other DTCs, refer to the Diagnostic Trouble Code (DTC) Chart in Section 419-10 .

10. If no DTCs related to the concern are retrieved, GO to Symptom Chart .

DTC Charts

 Audio Control Module (ACM) DTC Chart

NOTE: This module utilizes a 5-character DTC followed by a 2-character failure-type code. The failure-type code provides information about specific fault conditions such as opens, or shorts to ground. Continuous memory DTCs have an additional 2-character DTC status code suffix to assist in determining DTC history.

Pinpoint Tests

Pinpoint Test G: The Rear Video Is Inoperative

Refer to Wiring Diagrams Cell 131 , Parking Aid for schematic and connector information.

Normal Operation

For vehicles without navigation, with the gear selector in the REVERSE (R) position, a reverse voltage signal is sent to the auto-dimming interior mirror supplying power to the display in the mirror. The video camera signal is sent to the auto-dimming interior mirror. The video signal from the video camera displays an image on the LH side of the auto-dimming interior mirror.

For vehicles with navigation, with the gear selector in the REVERSE (R) position, a reverse signal is sent from the Instrument Panel Cluster (IPC) to the Audio Control Module (ACM) over the Medium Speed Controller Area Network (MS-CAN), enabling the system. The video signal from the video camera displays an image on the Front Display Interface Module (FDIM).

This pinpoint test is intended to diagnose the following:

• Fuse
• Wiring, terminals or connectors
• Video camera
• Auto-dimming interior mirror (without navigation)
• FDIM (with navigation)

PINPOINT TEST G: THE REAR VIDEO IS INOPERATIVE

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Section 414-01 .

Pinpoint Test H: Poor Image Quality

Refer to Wiring Diagrams Cell 131 , Parking Aid for schematic and connector information.

Normal Operation

For vehicles without navigation, with the gear selector in the REVERSE (R) position, a reverse voltage signal is sent to the auto-dimming interior mirror supplying power to the display in the mirror. The video camera signal is sent to the auto-dimming interior mirror. A pair of shielded wires carries the video signal from the video camera and displays an image on the LH side of the auto-dimming interior mirror.

For vehicles with navigation, with the gear selector in the REVERSE (R) position, a reverse signal is sent from the Instrument Panel Cluster (IPC) to the Audio Control Module (ACM) over the Medium Speed Controller Area Network (MS-CAN), enabling the system. A pair of shielded wires carries the video signal from the video camera and displays an image on the Front Display Interface Module (FDIM).

This pinpoint test is intended to diagnose the following:

• Wiring, terminals or connectors

• Auto-dimming interior mirror (without navigation)
• FDIM (with navigation)

PINPOINT TEST H: POOR IMAGE QUALITY

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Section 414-01 .

Pinpoint Test I: The Rear Video Mirror Display Is Always On (Vehicles Without Navigation)

Normal Operation

The video camera receives a supply voltage with the ignition switch in the RUN position. When the gear selector is in the REVERSE (R) position, a reverse voltage signal is sent to the auto-dimming interior mirror supplying power to the display in the mirror. The video camera signal is sent to the auto-dimming interior mirror. The video signal from the video camera displays an image on the LH side of the auto-dimming interior mirror.

This pinpoint test is intended to diagnose the following:

• Wiring, terminals or connectors
• Auto-dimming interior mirror
