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 ensure that you have the correct part. If you have the correct part, remove the faulty PCM and install the new service PCM.

Notice: 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, 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 P0602 indicates the EEPROM is not programmed or has malfunctioned.

1. Turn OFF the ignition.
2. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
3. Disconnect the IAT sensor electrical connector.
4. Remove the 3 bolts from the inner fender brace and remove the brace.
5. Loosen the clamps securing the air intake duct/mass air flow (MAF) sensor to the air cleaner housing and throttle body.
6. Carefully remove the air intake duct/MAF sensor from the throttle body and air cleaner housing (1).



7. Remove the 2 screws (2) from the 2 air cleaner housing sections.
8. Remove the air cleaner housing cover assembly.
9. Without disconnecting the PCM connectors, remove the PCM (4) and harness from the PCM housing (3).
10. Disconnect the PCM connectors.

1. Reconnect 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 from 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.

If a new PCM is being installed, program the EEPROM. Refer to Powertrain Control Module Programming
