       I don't know why the Maxi Sys Elite does not list or communicate with FCM (Front Control module )that is part of the CAN C communication network. This module is like a Body Control Module that piggy backs on the TIPM (Total Integrated Power Module)and controls some fused battery functions with the TIPM. I am trying to rule out loss of communication issues for a U0001 and u0002 codes to one of the CAN C network modules possibly taking the network down, but if I unplug this module I don't think much of anything electrical is going to function. Problem is dash light up like a christmas tree when stuff stops communicating on the CAN C network and transmission goes into limp mode.
      The Diagnostic repair software pinpoint tests for CAN C code U0001 says to connect to the FCM and Maxisys Elite Auto scan does not show FCM on the scan and FCM is not found in list of select-able modules. Why doesn't Autel Support this module yet on this 14 year old Chrysler product? From Windows PC I have my MP408 Maxi scoping the CAN C network at pin 11 and pin 15 of the ABS control module to give a decent image set at 1.0V div at 20us/div , but not seeing anything that either wire is being pulled to ground or shorted to battery.

     I was happy to see my MP408 scope worked good off my PC watching the CAN C communication. I didn't see any harness damage, and didn't want to access beneath Console and under dash for other module connectors, so luckily the local salvage yard recently got a 3.5L 2006 Charger I grabbed the TIPM and Front Control module off of even though the one I'm working on has a 5.7 L. Even though the part #s ended in a different letters, it's a POS old Dodge and worth a gamble. I swapped them out and made sure to put the fuses and relays from the old one into the replacement's  vacant fuse and relay positions since the TIPM from the 6 cylinder charger lacked some of the accessories of the 8 cylinder fully equipped vehicle possesses. I was very happy that all the electrical accessories worked , and there were no idiot lights or VIN mismatch codes generated from the different TIPM and FCM. I only had to. calibrate the steering angle sensor
