WHEN AN IDLE SHUTDOWN EVENT OCCURS, COMMUNICATION BETWEEN THE TCM AND THE EHCU IS TEMPORARILY SUSPENDED. THIS CAN CAUSE DTC U0101 (00) TO SET IN THE EHCU ALTHOUGH THERE IS NO FAULT IN THE SYSTEM.

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.
