Remedy To clear this fault: - clear the error memory of the vehicle (at least the ETC and ME) - put the vehicle to sleep (lock and wait) and wake up (unlock) - turn ignition ON and read error memory again - DTCs shouldn ́t be present in ETC - no CEL is turned ON - vehicle can be started and driven

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.
