Operation CHARM: Car repair manuals for everyone.

Without Scan Tool





1. After repair of the troubled areas, the Diagnostic Trouble Code (DTC) retained in the memory of the Engine Control Module must be cleared by removing the EFI fuse (15A) from the junction box number 2 for 10 seconds or more, with the Ignition Switch OFF.

NOTE: Cancellation can also be done by removing the battery negative (-) terminal. In this case, however, other memory systems; clock, radio presets, etc. will also be lost.
If it is necessary to to perform work on components requiring removal of the battery terminal, a check must first be made to see if DTC's have been recorded.

2. After cancellation, road test the vehicle to check that a normal code is now read on the Malfunction Indicator Lamp. If the same DTC appears, it indicates that the trouble area has not been repaired thoroughly.
