Clearing Trouble Codes

NOTE: This is the only information provided by the manufacturer for clearing diagnostic trouble codes for this system.

Clear the DTC.
The DTCs and freezed frame data will be erased by either action.
- Operating the OBDII scan tool (complying with SAE J1978) or TOYOTA hand-held tester to erase the codes. (See the OBDII 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 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 freezed frame data will be erased.
