Clearing Trouble Codes

  1. After performing repairs, clear ECM memory of all stored trouble codes and freeze frame data. Trouble codes and freeze frame data may be cleared using scan tester and scan tester manufacturer's instructions.
    NOTE: If using Toyota Scan Tester, trouble codes and freeze frame data may be cleared by switching from Check Mode to Normal Mode or from Normal Mode to Check Mode.
  2. Trouble codes and freeze frame data may also be cleared by removing EFI (15-amp) fuse from fuse/relay box. See FUSE/RELAY BOX LOCATION  table.
  3. Trouble codes and freeze frame data 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.
