So recently my 06 H3 had an issue in the transfer case where I would put it in 4-low, would hear it click in, and then right back out (while the car is in neutral). This would then throw a "Service 4WD" code on my dash that I ran as a "encoder circuit malfunction" and an "A/B motor circuit malfunction". All my other 4wd settings function fine and the car drives totally normal. I tore into it about a week ago, replaced the plastic shift fork with a aluminum one as many others have and that didn't solve it so I put a new encoder motor on which also failed to fix the issue. Using the original motor, I can press the 4-LOW button and it does the same thing with no transfer case connected to it. Simply rotates the half turn and then rotates back and throws a code. This is leading me to believe this would be an issue in the circuit for the 4wd system but even after looking at the schematic of how the signal is sent, I have no idea where to start looking. Does anybody have any insight or experience on issues like these? Any help would be greatly appreciated!
