With Manufacturer's Scan Tool

Clear the DTC

The DTCs and freeze frame data will be erased by either action.

1. Operating the OBD II scan tool (complying with SAE J1978) or TOYOTA hand-held tester to erase the codes. (See the OBD II scan tool's instruction book for operating instructions.)
2. Disconnecting the battery terminals or EFI and THROTTLE fuses.

NOTE: If the TOYOTA hand-held tester switches the ECM from the normal mode to the check mode or vice-versa, or if the ignition switch is turned from ON to ACC or OFF during the check mode, the DTCs and freeze frame data will be erased.
