Clearing Diagnostic Trouble Codes
DTC CLEARANCEThe 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.
