Clearing Trouble Codes

CLEARING CODES

NOTE: DO NOT disconnect the battery to clear continuous memory codes, as this will erase the Keep Alive Memory (KAM) information and may cause a driveability problem.

1. Perform the key ON engine OFF self-test (Refer to KEY ON ENGINE OFF SELF TEST for quick test procedures).
2. When the service codes begin to be displayed, DEACTIVATE the self-test by following the scanner manufacturers instructions.
3. The continuous memory codes will be erased from the Engine Control Assembly's (ECA) memory.
