Clearing Trouble Codes

  1. 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 the FUSE APPLICATION  table and FUSE/RELAY BOX LOCATION table.
  2. Depending on ambient temperature, fuse may need to be removed for more than 30 seconds, especially in colder temperatures. Install fuse. Road test vehicle. Ensure system operates properly (with no trouble codes) and MIL flashes continuously and evenly. 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.
  3. With certain trouble codes, once trouble code has been cleared from ECM memory, a trouble code detection test drive can be performed to verify repairs and that trouble has not reset. For information on code detection test drive, see DIAGNOSTIC TESTING  section.
