Clearing Diagnostic Trouble Codes
The following actions will erase the diagnostic trouble codes and freezed frame data.
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 diagnostic trouble codes and freezed frame data will be erased.
1. Operating the OBD-II scan tool (complying with SAE J 1978) 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.
NOTE: Disconnecting the battery will cause all memory systems (eg. radio stations, time, etc.) to be cleared.
