Notice: Turn the ignition OFF when installing or removing the PCM connectors and disconnecting or reconnecting the power to the PCM (battery cable, PCM pigtail, PCM fuse, jumper cables, etc.) in order to prevent internal PCM damage.

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. Turn OFF the ignition.

Caution: Refer to Battery Disconnect Caution in the Preface section.

3. Disconnect the negative battery cable.
4. Disconnect the mass air flow/intake air temperature (MAF/IAT) sensor electrical connector.
5. Loosen the intake air duct clamp at the throttle body.
6. Loosen the air filter element/PCM housing cover screws.
7. Remove the air filter element/PCM housing cover, the MAF/IAT sensor, and the intake air duct.
8. Disconnect both powertrain control module (PCM) connectors.
9. Remove the PCM.

Important: You must inspect the following areas before installing the PCM and insure that:

Important: If the PCM is being programmed using the Off-Board method, perform the programming before continuing with the steps listed below. Refer to the Off-Board procedure Service Programming System (SPS) in Programming.

1. Install the PCM.

Notice: Refer to Fastener Notice in the Preface section.

2. Install the PCM connectors.

Tighten
Tighten the PCM connectors screws to 8 N·m (71 lb in).

3. Install the intake air duct, the MAF/IAT sensor, and the air filter element/PCM housing cover to the throttle body.

Important: You must properly install the intake air duct to the throttle body. An improperly installed, distorted, or damaged air filter or intake air duct may cause a DTC to set.

4. Align and engage the tabs on the air filter element/PCM housing cover with the slots in the air filter element/PCM housing.
5. Tighten the air element/PCM housing cover screws

Tighten
Tighten the air element/PCM housing cover screws to 4 N·m (35 lb in).

6. Tighten the intake air duct clamp at the throttle body.

Tighten
Tighten the clamp to 3 N·m (27 lb in).

7. Reconnect the MAF/IAT sensor connector.
8. Connect the negative battery cable.

Important: The replacement PCM must be programmed.

9. Program the PCM. Refer to Service Programming System (SPS) in Programming.
