Powertrain Control Module (PCM) Replacement

NOTE: 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, the PCM should be inspected first to see if the PCM is the correct part. If the PCM is faulty, remove the PCM and install the new service 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: When replacing the production PCM with a service PCM, You must 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 electrically erasable programmable read only memory (EEPROM) will not be programmed. DTC P0602 indicates the EEPROM is not programmed or has malfunctioned.

Removal Procedure

CAUTION: Refer to Battery Disconnect Caution in Service Precautions.




1. Disconnect the negative battery cable.
2. Disconnect the intake air temperature (IAT) sensor.
3. Remove the 3 bolts from the inner fender brace and remove the brace.
4. Loosen the clamps securing the air intake duct and the mass air flow (MAF) sensor to the throttle body and air cleaner housing.
5. Carefully remove the air intake duct and MAF sensor from the throttle body and air cleaner housing (1).
6. Remove the 2 screws (2) from the 2 air cleaner housing sections.
7. Remove the air cleaner housing cover.
8. Without disconnecting the PCM connectors, remove the PCM (4) and the harness from the PCM housing (3).
9. Disconnect the PCM connectors.

Installation Procedure




1. Connect the PCM connectors.
2. Carefully install the PCM (4) and harness into the PCM housing (3).
3. Install the air cleaner housing cover assembly (1).
4. Install the 2 screws (2) to the 2 air cleaner housing sections.
5. Carefully install the air intake duct to the throttle body and air cleaner housing.
6. Tighten the clamp securing the air intake duct to the air cleaner housing.
7. Position the inner fender brace and install the 3 bolts.
8. Connect the negative battery cable.
9. If a replacement PCM is being installed, program the PCM. The replacement PCM will NOT allow secondary air injection (AIR) pump operation until a total of 16 km (10 mi) have accumulated.
10. If a replacement PCM is installed, perform the Powertrain Control Module (PCM) Programming. Programming and Relearning
