Immobilizer System Component Programming (without BTM)

Immobilizer System Component Programming (without BTM)

This procedure will learn the immobilizer function and require greater than 15 minutes to complete. If the battery voltage is low, charge the battery before proceeding with the learn. If the body control module (BCM) or engine control module (ECM) have been replaced, they must be programmed before performing this learn procedure.

Depending on the immobilizer function being learned or the component replaced, different learn functions are required to be performed. These learn functions are as follows:





1. Connect a scan tool to the vehicle and access SPS. Refer to Service Programming System (SPS) Service Programming System (SPS).

2. Turn ON the ignition, with the engine OFF.

3. Ensure that all power consuming devices are turned OFF on the vehicle.

4. Select SPS application and follow the on-screen instructions.

5. Select Reprogram ECU.

6. Select IMMO Immobilizer Learn.

7. Select the appropriate programming function based on the component that was replaced or is being programmed. Refer to the table at the top of this document for assistance in choosing the correct programming function.

8. Follow the on-screen instructions.

9. With a scan tool, clear any DTCs.
