Engine Control Module: Service and Repair

Powertrain Control Module (PCM)













Removal

1. NOTE: Refer to Computers and Control Systems Information 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 (Vehicle Communication Module).


2. Remove the Air Cleaner (ACL) assembly and ACL (Air Cleaner) outlet tube.

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 (Air Cleaner) assembly and ACL (Air Cleaner) outlet tube.

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 (Passive Anti-Theft System). For additional information, refer to Passive Anti-Theft System (PATS) Parameter Reset in Antitheft and Alarm Systems. Passive Anti-Theft System (PATS) Passive Anti-Theft System (PATS) Parameter Reset
NOTE: If the Programmable Module Installation (PMI) procedure was not successful in downloading the data from the vehicles original PCM, then the oil life data of the vehicle is lost. If this occurs, and the oil life cannot be determined through service history or customer interview, it is recommended the vehicle engine oil and filter be changed and the oil change minder reset.

Restore the module configurations for the IC (Instrument Cluster) module and the PCM. Carry out the module configuration restore steps of the Programmable Module Installation (PMI) procedure. Programmable Module Installation (PMI)
