Got a new Module from an 04+. The car starts fine with it and when I scan it I get no codes. But when I try to clear codes it says No communication to the EBCM(for either ebcm I have). What should I check now? Wiring? Whatever ground it is?
Also, this new EBCM has 2 metal "pins" on the inside center, and my old one didn't. Maybe the donor car had MagnaSteer and mine doesn't. Would that affect this?
