Engine Control Module: Service and Repair

Powertrain Control Module (PCM)













Removal

1. NOTE: Refer to Computers and Control Systems for correct Vehicle Communication Module (VCM) hook-up procedure.

If servicing the PCM, connect the scan tool to the vehicle. Allow the scan tool to identify the vehicle and obtain configuration data.

- All programmable module information will automatically be retrieved by the VCM.

2. Remove the Air Cleaner (ACL) assembly and ACL outlet tube. For additional information, refer to Intake Air Distribution and Filtering Intake Air System Components - Exploded View.

3. Disconnect the 3 PCM electrical connectors.

4. Remove the 2 retaining nuts and PCM.

Installation

1. Install the PCM and the 2 retaining nuts.
- Tighten to 7 Nm (62 lb-in).

2. Connect the 3 PCM electrical connectors.

3. Install the ACL assembly and ACL outlet tube. For additional information, refer to Intake Air Distribution and Filtering Intake Air System Components - Exploded View.

4. NOTE: If the PCM or Instrument Cluster (IC) is replaced (or both), the parameters must be reset in both modules or the vehicle will experience a Passive Anti-Theft System (PATS) no-start. This will occur even if the vehicle is not equipped with PATS. For additional information, refer to Passive Anti-Theft System (PATS) Parameter Reset in Anti-Theft - Passive Anti-Theft System (PATS) Passive Anti-Theft System (PATS).

Restore the module configurations for the IC module and the PCM. Carry out the module configuration restore steps of the Programmable Module Installation (PMI) procedure. For additional information, refer to Module Configuration Special Tool(s) Used With Diagnostics.
