I tought i had wire issue so i replaced the 10 pin connector and soldered all the wire with heat shrink and made sure all color are matched properly. but im still getting the same problem

Also which module is sending signal to the compressor relay cause i only have 12v on one of the wire( top one ).

Hi, I have the same problem. Did you find what was wrong? I think is the suspension module sending signal but am not sure if module bad, because computer not saying anything about that. How you sort a problem?

It looks like a problem connecting to a valve block. First delete the fault codes and see What will come back again because disconnecting the electrical plug to the valve block will produces these codes. Check the socket and electrical plug to the valve block
