Theory Of Operation

WARNING: This page is about a different car, the 2005 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

The Front Control Module isn't receiving an odometer signal over CAN B from the Cluster Module. The FCM has to send the PCM an odometer signal over CAN C. The signal the FCM is sending over CAN C is implausible.
