Clearing Trouble Codes

After any repairs are performed, clear ECU memory of all stored trouble codes. To clear memory, turn ignition off and remove appropriate fuse from fuse panel for 30 seconds. Cancellation can also be done by removing the battery negative terminal, but in this case other memory systems (radio, clock, etc.) will also be canceled out. See Fig 1.
