Hi guys, I’m having a P1633 code, I’m going to start fixing it and follow the link what stamp had posted. Hoping I’m not changing the pcm and hoping it’s just a battery terminal issue. If I need to check on the pcm harness, do I need to disconnect the battery first then unplug the harness(is it on the left side or right side,standing on the front of engine) then connecting back the battery?Can someone post the pcm pinout please as I need to check the voltage for the KAM issue. Thanks a lot.
