Clearing Trouble Codes
CLEARING DIAGNOSTIC TROUBLE CODESNOTE: This is the only information provided by the manufacturer for Clearing Diagnostic Trouble Codes for this system.
The DTCs and freeze frame data will be erased by either action.
- 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.)
- Disconnecting the battery terminals or EFI fuse.
NOTE: 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 DTCs and freeze frame data will be erased.
