My Zurich Pro scanner can perform the module calibration, but it can't complete the process due to seized ride height sensors. I'm not going to try to resolve this issue. I have no interest in spending time/money on a system I will never use again. Of course if I find it causing issues for other systems I may have to, we'll see.
So this code will remain:
C1991 - Module Calibration Fault. Vehicle Dynamics Module(VDM), basically air suspension.
I also got the driver mirror sensor codes again this morning unfortunately. After replacing the clutch coil in the transfer case I had 2 scans without the mirror codes, so it's intermittent now I suppose.
B2320 - Driver's mirror horizontal position sensor circuit fault. Driver Seat Module(DSM).
B2324 - Driver's mirror vertical position sensor circuit fault. Driver Seat Module(DSM).
Truth is all I have really learned from this entire process is that I'm not sure any of the testing/troubleshooting I did would have lead me to replacing the transfer case shift motor and clutch coil. I did occasionally get a code for the 4WD module when this started so maybe I'd have gotten there in the testing, but back then the shift motor and coil were still working.
I can likely resolve the mirror sensor faults, heck it could be due to the suspension calibration fault, LOL. Okay, that's unlikely but just as ridiculous as the shift motor/coil causing a communication bus issue that lead to nearly all the codes/faults identified in the first post of this thread. I just don't know that I care enough at this time to pursue it. I need to get a rusted rocker panel replaced first for sure.
I wish there was a feasible way to download the code for each system, then identify and eliminate the programming for the systems I don't want or use and then unplug those specific modules.
