Hello ,

My Tahoe 2011 LTZ Backup /rear view camera stopped working, I want to check if the problem from Head Unit, cable or from the Camera module itself,

I have tried to remove the camera assembly and reached up to the wiring of the back camera, wire red shows 12volt , yellow shows 5 volt , the others (white, grey, blue ) no voltage. its the same when I apply reverse or normal Park/neutral/Drive mode.

I need troubleshooting guide or wiring diagram to check, can anyone please help.

Thanks in advance

Have you checked where the wires come through the lift gate? Maybe chafed. New camera is cheap and fairly easy.
