NOTE: In order to prevent possible electrostatic discharge damage to the PCM, do not touch the connector pins or 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 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.
CAUTION: In order to prevent internal PCM damage, leave the ignition should be 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.).
REMOVE OR DISCONNECT
1. Disconnect the negative battery cable.
2. Remove the PCM sight shield (1).
3. Remove the PCM (3) from the mounting bracket (6).
4. Disconnect the harness connectors (2) from the PCM.
5. Remove the PCM from the engine compartment.
6. It the PCM is being replaced, remove the KS module for installation in the new PCM.
INSTALL OR CONNECT
NOTE: When replacing the production PCM with a service PCM (controller), 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.
1. If a new PCM is being installed, install the KS module from the original PCM.
2. Connect the harness connectors (2) to the PCM (3).
3. Install the PCM into the mounting bracket (6).
4. Install the PCM sight shield (1).
5. Connect the negative battery cable.
6. It a new PCM is being installed, program the EEPROM.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
