B222A-00-VEHICLE LINE MISMATCH

For a complete wiring diagram, refer to the Wiring Information.


Theory of Operation

The A/C Heater Controller checks for vehicle configuration using communication over the BUS. If the stored configuration does not match the configuration stored in the controller this DTC will set.



Possible Causes

VEHICLE CONFIGURATION NOT STORED IN THE TOTALLY INTEGRATED POWER MODULE (TIPM)
CONTROL MODULE INSTALLED IN INCORRECT VEHICLE
A/C HEATER CONTROL

Always perform the HVAC Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 28 - DTC-Based Diagnostics/HVAC - Standard Procedure) .


CHECK THE VEHICLE CONFIGURATION


NOTE: The DTC must be active and no BUS communication DTCs present before performing this test. If BUS communication DTCs are present, perform there respective test first. If the DTC is stored, erase the DTC and cycle the ignition. If the DTC resets and changes to active, then proceed.
1. With the scan tool, check the vehicle configuration stored in the Totally Integrated Power Module (TIPM).
2. With the scan tool, check the vehicle configuration stored in the A/C Heater Control (HVAC).


Pick the answer that best describes your findings:

TIPM has wrong or no vehicle configuration


HVAC has wrong vehicle configuration but TIPM has correct configuration.


HVAC and TIPM have proper calibration and the DTC is active in the HVAC.
