Clearing Trouble Codes

After any repairs are performed, clear ECU memory of all stored trouble codes. To clear memory, turn ignition off and remove 15A "EFI" fuse from fuse panel for 30 seconds. The lower the ambient (outside) temperature, the longer the fuse must be left out. Replace fuse and exit diagnostic mode.
