Powertrain Control Module: Service and Repair
Powertrain Control Module (PCM) Replacement
REMOVAL PROCEDURE
NOTE:
^
Check the resistance values of all PCM relays, solenoids, and other output controls before replacing or substituting the Powertrain Control Module
(PCM). Check all the sensor wiring and the PCM output control circuits for a short to ground before replacing or substituting the PCM. Perform
all circuit repairs or malfunctioning component part replacements before installing a replacement or substitute PCM. This will prevent damage to
the replacement or substitute PCM.
^
In order to prevent possible Electrostatic Discharge damage to the PCM, Do Not touch the connector pins or the soldered components on the
circuit board.
IMPORTANT: When replacing the production Powertrain Control Module (PCM) with a service PCM, transfer the broadcast code and production
PCM number to the service PCM label. This will allow for positive identification of the PCM throughout the service life of the vehicle.
