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.
NOTE: Do not touch the connector pins or soldered components on the circuit board in order to prevent possible electrostatic discharge (ESD) damage to the PCM.
NOTE: Turn the ignition OFF when installing or removing the PCM connectors and disconnecting or reconnecting the power to the PCM (battery cable, PCM pigtail, PCM fuse, jumper cables, etc.) in order to prevent internal PCM damage.
IMPORTANT: Service of the powertrain control module (PCM) consists of a complete replacement of the PCM. There are no serviceable parts, such as programmable read-only memory (PROM) or erasable programmable read-only memory (EPROM) to replace inside the PCM. If the PCM is determined to be faulty, the PCM is to be replaced as a complete assembly.
