P1634 - TCM Internal Internal Watchdog Performance ? P061B - Internal Control Module Torque Calculation Performance. ? U0401 - Implausible Data Received From The ECM/PCM. ?

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.
