Powertrain Control Module (PCM) Replacement

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

The new service PCM will not be programmed. You must program the new PCM. DTC P0602 indicates the EEPROM is not programmed or has malfunctioned.

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.
^ 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.

CAUTION: Refer to Battery Disconnect Caution in Service Precautions.




1. Disconnect the negative battery cable.
2. Remove the screws from the air cleaner top cover.
3. Remove the air cleaner top cover.




4. Disconnect the harness connectors from the PCM.




5. Remove the PCM from the air cleaner housing assembly.

INSTALLATION PROCEDURE

NOTE: Refer to Fastener Notice in Service Precautions.




1. Install the connectors to the PCM.

Tighten
Tighten the connectors to 8 N.m (71 lb in).

2. Install the PCM into the air cleaner housing assembly.




3. Install the air cleaner top cover.
4. Connect the negative battery cable.
5. The replacement PCM will NOT allow secondary AIR pump operation until a total of 10 miles have been accumulated.
6. The new PCM must be programmed. Programming and Relearning
