Pinpoint Test B: Module Configuration Faults
- 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 AWD P0630:00 VIN Not Programmed or Incompatible - ECM/PCM: No Sub Type Information The VIN stored in the AWD module does not match the value being passed by the PCM. AWD P160A:00 Control Module Vehicle Options Reconfiguration Error: No Sub Type Information The VIN, tire circumference, and axle ratio that are stored in the AWD module do not match the values being passed by the BCM. AWD U2100:00 Initial Configuration Not Complete: No Sub Type Information Sets when the AWD module detects initial configuration not complete. AWD U2101:00 Control Module Configuration Incompatible: No Sub Type Information Sets when the AWD module detects control module configuration incompatible. AWD U2200:00 Control Module Configuration Memory Corrupt: No Sub Type Information This DTC sets due to an internal fault with the AWD module. Possible Sources

Did the DTC set?
Yes CHECK OASIS for any applicable TSB, GSB, SSM, or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new AWD module. REFER to: All-Wheel Drive (AWD) Module . No The repair is complete.
