Operation CHARM: Car repair manuals for everyone.

With Generic Scan Tool

Clear the DTC

The DTCs and freeze frame data will be erased by either action.

- Operating the hand-held tester or OBD II scan tool (complying with SAE J1978) to erase the codes (See the OBD II scan tool's instruction book for operating instructions.).
- Disconnecting the battery terminals or remove the EFI fuse more than 60 seconds.






NOTE: If the 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 check mode, the DTCs and freeze frame data will be erased.
