MERCEDES BENZ C300 RADAR SENSOR FAULT

THIS MERCEDES BENZ HAD A PROBLEM WITH THE FRONT COLLISION RADAR SENSOR. NO COMMUNICATION WITH THE SENSOR DUE TO BROKEN POWER WIRE AND BROKEN COMMUNICATION WIRE AT THE MAIN DISCONNECT CONNECTOR RIGHT SIDE OF THE FRONT PUMPER. THIS IS A VERY GOOD PLACE TO LOOK AT FIRST IF YOU ARE EXPERIENCING THIS KIND OF COMMUNICATION PROBLEM WITH FRONT RADAR ON THESE C300 MERCEDES BENZ.

Do you have wiring diagram for that connector? What does each wire do

Thank you. I am facing the same problem now. Do you mean that you took the connector out? Just wonder how did you connected the two ends of each wire. By the way, I ever measured the resistance between green wire and yellow/green wire. The reading was 57 ohms. It indicates some continuity between the two lines. Is it normal or not? Your response will be appreciated.
