Powertrain Control Module (PCM) Replacement

PCM And Housing:

PCM REPLACEMENT / PROGRAMMING PROCEDURE

Notice: 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.

Service of the PCM should normally consist of either replacement of the PCM or EEPROM programming. If the diagnostic procedures call for the PCM to be replaced, PCM should be checked first to see if it is the correct part. If it is, remove the faulty PCM and install the new service PCM.

Notice: In order to prevent internal PCM damage, leave 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.).

Important: When replacing the production PCM with a service PCM, it is important to transfer the broadcast code and production PCM number to the service PCM label. Do not record on PCM cover. This will allow positive identification of PCM parts throughout the service life of the vehicle.

THE SERVICE PCM EEPROM WILL NOT BE PROGRAMMED. DTC PO6O2 indicates the EEPROM is not programmed or has malfunctioned.

REMOVAL PROCEDURE
1. Disconnect the negative battery cable.
2. Remove the left strut brace.
3. Remove the air cleaner housing cover.
4. Remove the PCM.
5. Disconnect the connectors from the PCM.
6. Remove the PCM from engine compartment.
7. If the PCM is being replaced, remove the PCM access cover to access the knock sensor module.

INSTALLATION PROCEDURE
1. If a new PCM is being installed, install the KS module from the original PCM.
2. Install the access cover on PCM.
3. Connect the connectors to PCM.
4. Install PCM into the air cleaner assembly.
5. Install the air cleaner assembly cover.
6. Negative baflery cable.

If a new PCM is being installed, program the EEPROM.
