Clearing Codes

Print

Stored faults should only be cleared by use of the DRB-II or similar scan tool. Disconnecting the battery will clear codes but is not recommended as doing so will also clear all other memories on the vehicle and may affect driveability. Unplugging the PCM connector will also clear codes, but on newer models it may store a power loss code and will affect driveability until the vehicle is driven and the PCM can relearn its driveability memory.

The -ERASE- screen will appear when ATM is pressed at the end of the stored faults. Select the desired action from ERASE or DON'T ERASE. If ERASE is chosen, the display asks ARE YOU SURE- Pressing ENTER erases stored faults and displays the message FAULTS ERASED. After the faults are erased, press ATM to return the FUEL/IGN MENU.
