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. Disconnect fusible link on Starlet models. See Fig 1. The lower the ambient (outside) temperature, the longer the fuse (fusible link) must be left out. Replace fuse or fusible link and exit diagnostic mode.
NOTE:
The lower the ambient temperature, the longer the fuse or fusible link must be left out.
