2. Disconnect the 2 Powertrain Control Module (PCM) electrical connectors.

3. Disengage and remove the PCM (Powertrain Control Module) cover.

4. Remove the 2 PCM (Powertrain Control Module) -to-PCM (Powertrain Control Module) support bracket bolts and the PCM (Powertrain Control Module).

5. If the PCM support bracket is damaged, remove the nut and position the ground cable aside and remove the 2 PCM (Powertrain Control Module) stud bolts and slide the PCM (Powertrain Control Module) support bracket out of the bulkhead.

6. Disconnect the Powertrain Control Module (PCM) electrical connectors.

7. Remove the stud bolts, the PCM (Powertrain Control Module) and the gasket.

Installation

Vehicles equipped with a 3.7L, 5.0L (4V) or 6.2L (2V) engine

1. Install the gasket, the PCM (Powertrain Control Module) and the 2 stud bolts.
- Tighten to 9 Nm (80 lb-in).


2. Connect the PCM (Powertrain Control Module) electrical connectors.

3. If the PCM (Powertrain Control Module) support bracket was removed, position the support bracket assembly into the bulkhead and install the 2 stud bolts.
- Tighten to 9 Nm (80 lb-in).


4. If the PCM (Powertrain Control Module) support bracket was removed, position the ground cable and install the nut.
- Tighten to 9 Nm (80 lb-in).


5. Position the PCM (Powertrain Control Module) onto the support bracket and install the 2 bolts.
- Tighten to 9 Nm (80 lb-in).


6. Install the PCM (Powertrain Control Module) cover.

7. Connect the 2 PCM (Powertrain Control Module) electrical connectors.

All engines

8. Carry out the transmission solenoid body strategy identification. For additional Information, refer to Automatic Transmission/Transaxle &/or Transmission Control Systems. Solenoid Body Strategy

9. 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 configuration. Carry out the module configuration restore steps of the Programmable Module Installation (PMI) procedure. For additional information, refer to Information Bus.

10. Perform the Passive Anti-Theft System (PATS) Parameter Reset procedure. For additional information, refer to Antitheft and Alarm Systems.

11. Using the scan tool, perform the Misfire Monitor Neutral Profile Correction procedure, following the on-screen instructions.
