Clearing Diagnostic Trouble Codes

DTC CLEARANCE
The following actions will erase the DTC and freeze frame data.
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 terminal cables or EFI fuse.

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