Pinpoint Test Ax: Module Configuration Faults

WARNING: This page is about a different car, the 2022 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.
  1. Normal Operation and Fault Conditions 

    A new AWD receives and saves vehicle identification (VID) block information from the PCM and BCM when the new AWD module powers up for the first time. During each subsequent module wake up, the AWD module compares the stored values to those being broadcast by the PCM and BCM. The diagnostic tool can be used to initiate a relearn procedure for the AWD module.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
