Operation CHARM: Car repair manuals for everyone.

With Generic Scan Tool

Clear the DTC

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

1. Operating the OBD II scan tool (complying with SAE J1978) or the hand-held tester to erase the codes (For operating instructions, see the OBD II instruction book).

2. Disconnecting the battery terminals or EFI1 fuse.

NOTE: If the hand-held tester switches the ECM from the normal mode to the check mode or vise-versa, or if the ignition switch is turned from ON to ACC or OFF during the check mode, the DTCs and freeze frame data will be erased.
