This procedure will learn the immobilizer function. 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:
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 immobilizer 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 immobilizer 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 immobilizer 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 immobilizer 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 immobilizer 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. Refer to the SPS application to determine if a particular vehicle is able to add keys using this method. |
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 |
