Powertrain Control Module: Service and Repair
PCM Location
The PCM is mounted underhood near the brake booster.
The PCM engine control strategy prevents reduced idle speeds until after the engine operates for 320 Km (200 miles). If the PCM is replaced after 320
Km (200 miles) of usage, update the mileage and vehicle identification number (VIN) in the new PCM. Use the DRB scan tool to change the millage
and VIN in the PCM. If this step is not done a diagnostic trouble code (DTC) may be set. Refer to Testing and Inspection.
REMOVAL
To avoid possible voltage spike damage to PCM, ignition key must be off, and the negative battery cable must be disconnected before unplugging the
PCM connectors. Note radio programs.
