Circuit/System Verification

1. Inspect the rearview camera for any debris on the lens or a damage bezel or bezel seal. Clean any debris from the lens. If the lens, bezel, or bezel seal are damaged, replace as necessary
2. Ignition ON, vehicle in PARK, verify the backup lamps are OFF. If the backup lamps are illuminated, refer to «Circuit/System Testing»(ref-299185-S16393717522008092200000) .
3. Command the backup lamps ON with a scan tool, a clear rearview image should be displayed on the rearview camera display. If a clear image is not displayed, refer to «Circuit/System Testing»(ref-299185-S16393717522008092200000) .

Repair Procedures

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

Scheme 2

The object detection system can help a driver determine how close an object is to the rear bumper within a predefined rearward field of view. The system is composed of a video camera located on the rear bumper, electrical harness and a 3.5 inch LCD display intergral to the inside rearview mirror (ISRVM). All mirror features will default to ON with each ignition cycle. The object detection system can be disabled by pressing the rear vision ON/OFF button when the ignition switch is in the ACCESSORY or RUN position. When the object detection power button is pressed the indicator to the right of the power button will turn off verifying that the system is OFF.

The mirror requires an active high (12 volt) signal from the body control module (BCM) to enable the rear vision system. This signal is provided by placing the transmission in reverse. When the transmission is in the reverse, the ISRVM will supply the camera with a regulated 12-volt power source. The same control signal will also disable the auto dimming feature of the ISRVM. The LCD display will deploy in less than 3 seconds and remain deployed until the transmission is moved out of the reverse position. Once the transmission is moved out of the reverse position the display will retract in 2-3 seconds. Anything preventing the display from fully extending will cause the display to retract.

The mirror can be placed into a service mode to facilitate screen cleaning. With the ignition in the ACCY position, press and hold the rear vision power button for 5-8 seconds or until the display is deployed. The display will remain deployed for 30 seconds. Do not attempt to pull out the display as that may cause internal damage.

The object detection system has the following diagnostic capabilities

1. The rear vision ON/OFF indicator will flash with the absence of a proper video signal
2. The rear vision ON/OFF indicator will flash when interference of the display deployment has been detected

To begin diagnostics refer to Diagnostic Starting Point - Object Detection .
