Immobiliser System Component Programming - with BTM

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	ECU	Keys	Function Description	When the Function Should Be Used	Notes
Program Transponder & Remote Key	--	--	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	-
Program Immobiliser Function	BCM (Body Control Module)	Use Existing Transponder-Keys	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	-
Program Immobiliser Function	BCM (Body Control Module)	Use New Transponder-Keys	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 used	-
Program Immobiliser Function	BCM (Body Control Module) and ECM (Engine Control Module)	-	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 Immobiliser Function	ECM (Engine Control Module)	-	The ECM will relearn the immobiliser passwords and data	The ECM has been replaced or a diagnostic has instructed to perform the learn	-

Notes

Program Transponder & Remote Key

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

Program Immobiliser Function

BCM (Body Control Module)

Use Existing Transponder-Keys

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

Program Immobiliser Function

BCM (Body Control Module)

Use New Transponder-Keys

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 used

Program Immobiliser Function

BCM (Body Control Module) and ECM (Engine Control Module)

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 Immobiliser Function

ECM (Engine Control Module)

The ECM will relearn the immobiliser passwords and data

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

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

Turn ON the ignition, with the 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 Immobiliser Learn.

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 ignition to the run position. Make sure the vehicle is actually in the run mode before continuing on the SPS terminal. If the igniting is not in the run mode, the learn procedure will fail. To verify the vehicle is in Run mode, verify the green LED is illuminated on the ignition mode switch.

•

The key pocket is located inside the centre console storage area. The key must be placed flat in the pocket with the buttons facing up and the keyring on the right. If a large key ring prevents the key from laying flat in the pocket, remove the keyring and place the key in the pocket. Failure to position the key flat in the pocket will result in an inability to program.

Follow the on-screen instructions.

When the SPS procedure has completed, press and hold the ignition mode switch for 15 seconds.

With a scan tool, clear any DTCs.
