Rear Vision Camera System Malfunction

When the transmission is placed into REVERSE, a 12 volt signal is sent to the navigation unit indicating that camera operation is requested. The navigation unit then supplies reference voltage and ground to the rear vision camera. The rear vision camera sends video information to the navigation unit through a video signal + and a video signal - circuit. A grounded shielding also wraps the video signal circuits to reduce electronic interference which may degrade the video signal and cause a distorted or otherwise degraded image.

A poor video image can be caused by ice, snow, and mud build-up on the lens of the rear view camera. Also, extreme lighting conditions can affect performance, such as operating in the dark or with bright sunlight shining on the camera. Extreme high or low temperatures can also affect the image quality. For normal operating characteristics of the rear vision camera system, refer to the Navigation System section of the owners manual.

Electrical Information Reference

1. Inspect the rearview camera and verify there is no debris on the lens or that the bezel or bezel seal is not damaged.

⇒	If debris is found on the lens, clean the lens. If the lens, bezel, or bezel seal are damaged, replace as necessary.

2. Ignition ON, vehicle in PARK, verify the back-up lamps are off.

⇒	If the back-up lamps are illuminated, refer to Rear Vision Camera System Always On.

3. Vehicle in REVERSE, verify a clear rear vision image is displayed on the radio.

⇒	If a clear image is not displayed, refer to Rear Vision Camera System Does Not Display.

Rear Vision Camera System Always On

1. Ignition OFF, disconnect the harness connector at the rear view camera.
2. Ignition ON, vehicle in PARK, verify a test lamp does not illuminate between the enable circuit terminal 5 and ground.

⇒	If the test lamp illuminates, test the control circuit for a short to voltage. If the circuit tests normal, refer to Symptoms - Lighting .

3. If all circuits test normal, replace the rearview camera.

Rear Vision Camera System Does Not Display

1. Ignition OFF, disconnect the harness connector at the rearview camera.
2. Test for less than 30.0 Ω between the ground circuit terminal 3 and ground.

⇒	If greater than the specified range, test the ground circuit for an open/high resistance. If the circuit tests normal, replace the navigation unit.

3. Ignition ON, handbrake applied, vehicle in REVERSE, verify that a test lamp illuminates between the enable circuit terminal 5 and ground.

⇒	If the test lamp does not illuminate, test the enable circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the navigation unit.

4. Disconnect the harness connector at the navigation unit.
5. Ignition ON, test for less than 1 volt between the following signal circuits at the rear view camera harness connector and ground:

•	Video + signal circuit terminal 2

•	Video - signal circuit terminal 4

⇒	If greater than the specified range, test the video circuit for a short to voltage.

6. Test for infinite resistance between the following signal circuits at the rear view camera harness connector and ground:

•	Video + signal circuit terminal 2

•	Video - signal circuit terminal 4

⇒	If not the specified value, test the signal circuit for a short to ground.

7. Test for less than 5 Ω between the signal (+) circuit terminal 2 at the rearview camera harness connector and the signal (+) circuit terminal 13 at the navigation unit connector X2.

⇒	If greater than the specified range, test the signal circuit for an open/high resistance.

8. Test for less than 5 Ω between the signal (-) circuit terminal 4 at the rearview camera harness connector and the signal (-) circuit terminal 15 at the navigation unit connector X2.

⇒	If greater than the specified range, test the signal circuit for an open/high resistance.

9. If all circuits test normal, test or replace the rearview camera.
10. All harness connectors connected, ignition ON, transmission in REVERSE, verify a clear vision image is displayed on the navigation unit.

⇒	If a clear rear vision image is not displayed, replace the navigation unit.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
