2002 Chevrolet Monte Carlo V6-3.8L VIN KSECTION Powertrain Control Module (PCM) Replacement
Service of the powertrain control module (PCM) should normally consist of either replacement of the PCM or electrically erasable programmable read only memory (EEPROM) programming. If the diagnostic procedures call for PCM replacement, inspect the PCM first to see if the replacement is the correct part. If the PCM is faulty, remove the PCM 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.
Removal Procedure
1. Disconnect the negative battery cable.
2. Remove the air cleaner housing cover assembly.
3. Without disconnecting the powertrain control module (PCM) connectors, remove the PCM (4) and the harness from the air cleaner housing.
4. Disconnect the PCM harness connectors.
Installation Procedure
NOTE: Refer to Fastener Notice in Service Precautions.
1. Install the PCM to the harness connectors.
Tighten
Tighten the connectors to 8 N.m (71 lb in).
2. Install the PCM (4) and the harness into the air cleaner housing.
3. Install the air cleaner housing cover assembly.
4. Connect the negative battery cable.
IMPORTANT: The replacement PCM will NOT allow secondary air injection (AIR) pump operation until a total of 16 km (10 ml) have been accumulated. The new PCM must be programmed.
5. Program the new PCM. Programming and Relearning

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.
