Hello,

I have a problem with front GM radar sensors. There is PCM error and parktronic do not working. This car is after car accident, the front bumper was damaged. I bought some new parts and replaced. I bought new wiring and two identical front GM radar sensors number 84112235. I marked left one on the picture. There is PCM error - left side. My question - Are the left and right sensors the same? Or is the left sensor different than right one? What parts number are these sensors? Why is there only left sensor error?
I am waiting for your reply.
Have a nice day,
Pawel

Yes, there are two object sensors for each position, 2 right front 2 left front, 2 right rear and 2 left rear. Here is the parking assistant wiring diagrams as requested, you can see the color wiring that go to the correct sensor for clarification.

Thank you for your reply. Could you please tell me if radar sensor number 84112235 is it the same part as object sensor? There are 2 pcs of radar sensor front only. And there are 4 pcs of other sensors. I think that it is not the same sensors.

The Forward Collision Alert Sensor was the problem, it was faulty. After replacing the radar sensor started working.
Thank you Ken :-)
