CLEARING FAILURE CODES
Notice:To prevent Engine Control Module (ECM) damage, the key must be OFF when disconnecting or reconnecting
the power to the ECM (for example battery cable, ECM pigtail connector, ECM fuse, jumper cables, etc.)
Parameters listed in the table may not be exactly the same as your reading due to the type of instrument or other
factors. If a failure code is displayed during the “TROUBLE CODE” in scan tool check mode, check the circuit for the
code listed in the table below. For details of each code, turn to the page referred to under the “See Page” for the re-
spective “Failure Code” in the below table.
Failure codes should be cleared after repairs have been completed.
