DIAGNOSTIC TROUBLE CODE DIAGNOSIS
CLEARING TROUBLE CODES
Notice: To prevent Engine Control Module (ECM) dam-
age, the key must be OFF when disconnecting or recon-
necting the power to the ECM (for example battery
cable, ECM pigtail connector, ECM fuse, jumper cables,
etc.).When the ECM sets a Diagnostic Trouble Code
(DTC), the Malfunction Indicator Lamp (MIL) lamp will
be turned on only for type A, B and E but a DTC will be
stored in the ECM’s memory for all types of DTC. If the
problem is intermittent, the MIL will go out after 10 sec-
onds if the fault is no longer present. The DTC will stay
in the ECM’s memory until cleared by scan tool. Remov-
ing battery voltage for 10 seconds will clear some stored
DTCs.
DTCs should be cleared after repairs have been com-
pleted. Some diagnostic tables will tell you to clear the
codes before using the chart. This allows the ECM to set
the DTC while going through the chart, which will help to
find the cause of the problem more quickly.
