Clearing Trouble Codes

After any repairs are performed, clear ECM memory of all stored trouble codes. To clear memory, turn ignition off and remove the "STOP" 15 amp fuse located behind driver's kick panel for 10 seconds or more. The lower the ambient (outside) temperature, the longer the fuse must be left out. Reinstall fuse and exit diagnostic mode.
