Clearing Codes
- After repairs are performed, clear PCM memory of all stored codes. Ensure ignition is off. To clear codes, use diagnostic scan tool CLEAR DTCS or CLEAR INFO function. Follow instructions supplied by tool manufacturer when clearing DTCs.
- DTCs can also be cleared by disconnecting the PCM power source or negative battery cable for at least 30 seconds. However, if disconnecting battery, remember that other memory functions (clock, radio, etc.) will need to be reset.
