CONDITION SUMMARY

Situation: Intermittently with the vehicle stationary during an AUTO Stop/Start event, the vehicle may completely shut down, particularly if the driver has moved the Transmission Control Switch (TCS) to Neutral (N). In these instances, a new ignition cycle must be performed to restart the engine. Upon engine restart, a 'Transmission Fault' message on the Instrument Cluster (IC) may be displayed in the Instrument Cluster combined with either an inability to pull away or failure to engage gear. Upon diagnosis, the Diagnostic Trouble Code (DTC) U0121-87 'Missing Message' is found stored in the Transmission Control Module (TCM).

Cause: This may be caused when during an AUTO Stop/Start event, the current ABS software may prevent a continuous signal being transmitted to the Transmission Control Module (TCM) resulting in a lost communication fault.

Action: Should a customer express this concern, follow the Service Instruction below.
