TCM-0A31: Control Module Communication. Signal Missing From Engine Control Module (ECM) (B5254T4, TF-80SC AWD; 2006-2007): Fault-tracingTCM-0A31: Information
No troubleshooting has been developed for this diagnostic trouble code.
The diagnostic trouble code (DTC) for CAN communication can also be stored in the Central Electronic module (CEM). In certain instances the diagnostic trouble code (DTC) is also set in other affected control modules. This diagnostic trouble code (DTC) must not be erased before any diagnostic trouble codes (DTC) in the Central Electronic Module (CEM), for CAN communication, and in the Engine Control Module (ECM) have first been remedied and erased.
First read off the diagnostic trouble codes (DTCs) in the central electronic module (CEM) and the engine control module (ECM). Fault-trace and remedy as necessary. If no diagnostic trouble codes (DTCs) are stored, fault-trace the controller area network (CAN) as follows. This diagnostic trouble code (DTC) can then be erased.
For more information about the diagnostic trouble code (DTC) see diagnostic trouble code (DTC) information.
