Clearing Trouble Codes
- After performing repairs, clear ECM memory of all stored trouble codes. To clear memory, turn ignition off. Remove proper fuse from fuse/relay box for approximately 30 seconds or more. See FUSE/RELAY BOX LOCATION table. See FUSE APPLICATION table to remove proper fuse.
- Depending on ambient temperature, fuse may need to be removed for more than 30 seconds in colder temperatures. Install fuse. Road test vehicle, and ensure system operates properly. See Figure.
NOTE:
Trouble codes may also be cleared by disconnecting negative battery cable. However, other memory functions (clock, radio, alarm, seats, etc.) will be canceled and must be reset.
