Engine Control Module: Component Tests and General Diagnostics
Powertrain Control Module (PCM) Diagnosis
To read and clear diagnostic trouble codes, use a Tech 2.
IMPORTANT: Use of a Tech 2 is recommended to clear diagnostic trouble codes from the PCM memory. Diagnostic trouble codes can also be cleared
by turning the ignition OFF and disconnecting the battery power from the PCM for 30 seconds. Turning off the ignition and disconnecting the battery
power from the PCM will cause all diagnostic information in the PCM memory to be cleared. Therefore, all the diagnostic tests will have to be re-run.
Since the PCM can have a failure which may affect only one circuit, following the diagnostic procedures in this section will determine which circuit has a
problem and where it is.
If a diagnostic chart indicates that the PCM connections or the PCM is the cause of a problem, and the PCM is replaced, but this does not correct the
problem, one of the following may be the reason:
-
There is a problem with the PCM terminal connections. The terminals may have to be removed from the connector in order to check them
properly.
