Important: 

Important: Remove any debris from the PCM connector surfaces before servicing the PCM. Inspect the PCM module connector gaskets when diagnosing/replacing the PCM. Ensure that the gaskets are installed correctly. The gaskets prevent contaminate intrusion into the PCM.

Notice: 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.

Important: The ignition should always be OFF when installing or removing the PCM connectors.

Important: It is necessary to record the remaining engine oil life. If the replacement module is not programed with the remaining engine oil life, the engine oil life will default to 100%. If the replacement module is not programmed with the remaining engine oil life, the engine oil will need to be changed at 5000 km (3,000 mi) from the last engine oil change.

1. Using a scan tool, retrieve the percentage of remaining engine oil. Record the remaining engine oil life.
2. Remove the wheelhouse filler panel. Refer to Wheelhouse Filler Replacement in Body Front End.
3. Remove the TAC module. Refer to Electronic Throttle Actuator Control Module Replacement .



4. Disconnect the PCM electrical harness connectors.
5. Loosen but do not remove the PCM rear retaining fastener. Use the rear retaining fastener as an anchor for the outer bracket.
6. Remove the front retaining fastener from the PCM.
7. Reposition the PCM outer bracket.



8. Remove the PCM from the bracket and the vehicle.

1. Install the PCM to the PCM rear bracket.
2. Position the PCM front bracket.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Install the PCM front retaining fasteners.

Tighten
Tighten the PCM retaining fasteners to 2.2 N·m (17 lb in).




4. Connect the electrical connectors to the PCM.

Tighten
Tighten the PCM electrical connectors to 8 N·m (70 lb in).

5. Install the TAC module. Refer to Electronic Throttle Actuator Control Module Replacement .
6. Install the wheelhouse filler panel. Refer to Wheelhouse Filler Replacement in Body Front End.
7. Program the PCM if a new PCM is being installed.

Setup

1. Ensure that the following conditions have been met:

•	The battery is fully charged.

•	The scan tool cable connection at the DLC is secure.

2. Turn OFF the ignition.
3. Remove the passenger side (right side of vehicle) floor access panel. Refer to Front Floor Kick-Up Panel Replacement in Interior Trim.



4. Remove the splice pack/star connector shorting bars from both splice pack/star connectors (2 and 3). It may be necessary to remove splice pack/star connectors from the mounting positions.
5. Install the Star Connector cable #1 from the J 42236 to the 12 pin splice pack/star (3). This is the connector with 8 or 9 wires.
6. Install the Star Connector cable #2 from the J 42236 to the 12 pin splice pack/star (2). This is the connector with 4 wires.
7. Select the Star Connector cable #1 on the J 42236 toggle switch.
8. Select position B on the J 42236 .
9. Turn ON the ignition leaving the engine OFF.
10. Program the PCM using the latest software matching the vehicle. Review the Techline™ terminal/equipment users instructions.

•	If the PCM fails to program, proceed as follows:

-	Ensure that all PCM connections are OK.

-	Ensure that all connections at the splice pack/star connectors are OK.

-	Verify the Techline terminal/equipment for the latest software version.

-	Attempt to program the PCM. Replace the PCM if the PCM still cannot be programmed properly.

•	Program the replacement PCM.

11. Perform the PCM Password Learn procedure if a new PCM is installed. Refer to DTC P1631 Theft Deterrent Start Enable Signal Not Correct .
12. Perform the PCM Idle Learn procedure. Refer to Idle Learn .

1. Clear the Diagnostic Trouble Codes (DTCs).
2. Perform the On-Board Diagnostic System Check.
3. Start the engine and run for 1 minute.
4. Scan for DTCs using the scan tool.
