- Unknown or other
- Summary
- Emission Recall. General Motors has decided to conduct a Voluntary Emission Recall involving certain vehicles. The Transmission Control Module (TCM), after detecting a loss of communications fault with other control modules, may incorrectly clear the loss of communications Diagnostic Trouble Codes (DTCs) when the vehicle is keyed off and, if the loss of communications fault persists, may not detect it again when the vehicle is keyed back on. If this were to happen, the transmission could operate in a default mode with no DTC set and the MIL not illuminated. Dealers are to reprogram the Transmission Control Module (TCM) with updated software.
