Xc60 park sensors

[Justinas]

Hello. I have some problem with retrofit front park sensors. Car have only rear park sensors. Now I connected front to the cem, changed configuration front+rear, and allways getting this error. Front park sensors have clicking noise, all signals there on wiring. Any ideas ? Tried brown sensors, same errors

Either you have a short or wrong wiring. Sensors should not make clicking noise all the time. Only when they detect a close object.

Okay. Do you maybe have wiring for xc60 ? I found here wiring where to connect pins
45 - 44 + 41,40,39,38 signals. It’s wrong pins ?

They clicking only when starting car, not allways. I haven't check cem hardware if it’s low or high. I doubt that wiring bad, becouse when disconnecting any inner sensor error appears

I have cem with HI letters

2 possible options:
1 - Is small support battery OK? If not, replace it with new one
2 - If you have access to Vida, use CEM service procedure called "Enable disabled pins"
