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 terminals or EFI fuse.
- This will erase all memory functions (clock, radio presets, etc) so note them before disconnecting the battery terminals.


NOTICE: If a Toyota Hand-Held Tester is used to switch 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.
