Manufacturer summary

Original wording in English

Service Update. Certain vehicles may incorrectly report to test tools an active permanent status of Transmission Control Module (TCM) Diagnostic Trouble Code (DTC) P2781 (Downshift Switch Circuit High). This could cause the vehicle to not pass an emissions inspection test in jurisdictions that check the permanent status of DTCs as part of an emissions testing program. Reprogram the TCM with updated software.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
