Rear view camera failure

Circuit/System Description
When the transmission is placed into REVERSE, a 12 volt signal is sent to the rearview camera image display module indicating that camera operation is requested. The rearview camera image display module then supplies ignition voltage and ground to the rear vision camera. The rear vision camera sends video information through the rearview camera image display module to the inside rearview mirror 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.

Rear Vision Camera System Does Not Display
Ignition OFF, disconnect the harness connector at the rear view camera image display module.
Test for less than 1.0 ohm between the ground circuit terminal 3 and ground.
? If greater than the specified range, test the ground circuit for an open/high resistance.
Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 2 and ground.
? If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
Ignition ON, park brake applied, vehicle in REVERSE, verify that a test lamp illuminates between the control circuit terminal 1 and ground.
? If the test lamp does not illuminate, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM.
Ignition OFF, connect the harness connector at the rear view camera image display module. Disconnect the harness connector at the rearview camera.
Ignition OFF, test for less than 1.0 ohm between the ground circuit terminal B and ground.
? If greater than the specified range, test the ground circuit for an open/high resistance. If the circuit tests normal, replace the rear view camera image display module.
Ignition ON, park brake applied, vehicle in REVERSE, test for 5.8-6.2 volts between the 6-volt reference circuit terminal A and ground.
? If less than the specified range, test the 6-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the rear view camera image display module.
? If greater than the specified range, test the 6-volt reference circuit for a short to voltage. If the circuit tests normal, replace the rear view camera image display module.
Ignition OFF, disconnect the harness connector at the rear view camera image display module.
Test for less then 1 ohm between the shield ground circuit terminal 10 at the rear vision camera display module harness connector and terminal D at the rear vision camera harness connector.
? If greater than the specified range, test the shield ground circuit for an open/high resistance.
Ignition ON, test for less than 1 volt between the signal circuit terminal 9 and ground.
? If greater than the specified range, test the signal circuit for a short to voltage.
Test for infinite resistance between the signal circuit terminal 9 and ground.
? If not the specified value, test the signal circuit for a short to ground.
Test for less then 1 ohm between the signal circuit terminal 9 at the rear vision camera display module harness connector and terminal C at the rear vision camera harness connector.
? If greater than the specified range, test the signal circuit for an open/high resistance.
Ignition OFF, disconnect the harness connector at the inside rearview mirror.
Ignition ON, test for less than 1 volt between the following signal circuits at the inside rearview mirror harness connector and ground:
• Video + signal circuit terminal 6
• Video - signal circuit terminal 7
Test for infinite resistance between the following signal circuits at the inside rearview mirror harness connector and ground:
? If greater than the specified range, test the signal circuit for a short to voltage.
• Video + signal circuit terminal 6
• Video - signal circuit terminal 7
? If greater than the specified value, test the signal circuit for a short to ground.
Test for less then 1 ohm between the following signal circuits:
• Signal circuit terminal 12 at the rearview camera image module and terminal 6 at the inside rearview mirror.
• Signal circuit terminal 11 at the rearview camera image module and terminal 7 at the inside rearview mirror.
? If greater than the specified range, test the signal circuit for an open/high resistance.
If all circuits test normal, test or replace the rear vision camera.
Ignition ON, park brake applied, vehicle in REVERSE, verify a clear rear vision image is displayed on the radio.
? If a clear rear vision image is not displayed, test or replace the inside rearview mirror

How to Reverse the Image on Backup Camera eHow

EVERYTHING YOU NEED TO KNOW ABOUT REAR VIEW CAMERAS

After installing a backup camera on your vehicle, you need to reverse the image so that the image on the screen matches that of your rear-view mirror. The orientation must match so that the driver doesn't get confused with two conflicting images. The nature of the camera's technology is that its image will be recorded un-reflected, but the mirror will display a reflected image. Fortunately, the engineers who designed back-up cameras thought of this and created simple controls for you to change the orientation.

There are two tiny motors in each mirror. one for up/down. One for side to side. They have jack screws (plastic) that fit into the motors.

You can manually put your hands on either side of the mirror and force adjust it. If you hear a ratcheting sound, the jack screws are OK. Then repeat with hands on top and bottom.

If you hear ratcheting and mirror stays where you stop it, that means one of the motors is bad. The motor assembly is available as a separate part.

You will need to remove the triangular panel on the inside of the door on the opposite side of the broken mirror. Once you remove the panel, you will see the retaining bolts holding the mirror in place. Once you remove the bolts, the mirror can then be pulled out from the outside. Reverse the procedure to reinstall the new mirror.
