Immobiliser System Component Programming

This procedure will learn the immobiliser function and require more 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 immobiliser function being learned or the component replaced, different learn functions are required to be performed. These learn functions are as follows:

Function name on SPS tool:	Function description:	When the function should be used:	Notes:
Body Control Module IMMO Function with Existing Transponder or Remote Key	The BCM will relearn the immobiliser passwords and data while reusing the existing vehicle keys	The BCM has been replaced and the existing vehicle keys are being reused or a diagnostic has instructed to perform the learn	-
Body Control Module IMMO Function with New Transponder or Remote Key	The BCM will relearn the immobiliser passwords and data while using new vehicle keys	The BCM has been replaced and new vehicle keys are being reused	-
Engine Control Module IMMO Learn	The ECM will relearn the immobiliser passwords and data	The ECM has been replaced or a diagnostic has instructed to perform the learn	-
Engine Control Module and Body Control Module IMMO Learn	The ECM and BCM will learn new immobiliser passwords and data	Both the ECM and BCM have been replaced (this selection will REQUIRE new vehicle keys be used)	Because both the ECM and BCM have been replaced and are learning new immobiliser passwords and data, all vehicle keys must also be replaced
Program Transponder or Remote Key (Add)	A new vehicle key will learn the immobilizer passwords and data	A new vehicle key is being added (does not affect other vehicle keys)	This function may not be available in all sales regions
Program Transponder or Remote Key (Delete)	All existing vehicle keys will be invalidated and any desired keys are relearned	All vehicle keys are desired to be invalidated and certain keys relearned or a diagnostic has instructed to perform the learn	This procedure may be used if a customer has had their keys lost or stolen and wishes to invalidate the keys, making them unable to start the vehicle

Notes:

Body Control Module IMMO Function with Existing Transponder or Remote Key

The BCM will relearn the immobiliser passwords and data while reusing the existing vehicle keys

The BCM has been replaced and the existing vehicle keys are being reused or a diagnostic has instructed to perform the learn

Body Control Module IMMO Function with New Transponder or Remote Key

The BCM will relearn the immobiliser passwords and data while using new vehicle keys

The BCM has been replaced and new vehicle keys are being reused

Engine Control Module IMMO Learn

The ECM will relearn the immobiliser passwords and data

The ECM has been replaced or a diagnostic has instructed to perform the learn

Engine Control Module and Body Control Module IMMO Learn

The ECM and BCM will learn new immobiliser passwords and data

Both the ECM and BCM have been replaced (this selection will REQUIRE new vehicle keys be used)

Because both the ECM and BCM have been replaced and are learning new immobiliser passwords and data, all vehicle keys must also be replaced

Program Transponder or Remote Key (Add)

A new vehicle key will learn the immobilizer passwords and data

A new vehicle key is being added (does not affect other vehicle keys)

This function may not be available in all sales regions

Program Transponder or Remote Key (Delete)

All existing vehicle keys will be invalidated and any desired keys are relearned

All vehicle keys are desired to be invalidated and certain keys relearned or a diagnostic has instructed to perform the learn

This procedure may be used if a customer has had their keys lost or stolen and wishes to invalidate the keys, making them unable to start the vehicle

Connect a scan tool to the vehicle and access SPS.

Vehicle in Service Mode, engine OFF.

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

Select SPS application and follow the onscreen instructions.

Select Reprogram ECU.

Select IMMO Immobilizer Learn - Setup.

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.

Note:

•	At multiple times during the learn procedure, SPS will instruct you to turn the vehicle to Service Mode. Make sure the vehicle is actually in the Service Mode before continuing on the SPS terminal. If the vehicle is not in the Service Mode, the learn procedure will fail.

•	The transmitter slot is located inside the upper instrument panel storage compartment. The rubber mat lining at the bottom of the compartment needs to be removed to access the slot.

Follow the on-screen instructions.

After programming all keys "Programming Complete" is displayed.

Press and hold the vehicle ON/OFF switch for 15 seconds.

Press the lock and unlock button on each transmitter that was programmed. This will awaken each transmitter and allow passive and active keyless entry functions to be established.

With a scan tool, clear any DTCs.

Verify each key is operating properly. Operate each of the keyless entry functions using the buttons on the transmitter and then start the vehicle. When verifying operation, make sure that no other keys are near the vehicle.
