-
BCM Programming Process: Initiate the BCM programming process within SPS. Note: This step can take between 10 to 12 minutes. The progress bar may appear to stop, but this is a normal security timer response. Do not interrupt or restart the process.
-
Immobilizer Learn Procedure: If DTC B389A sets immediately after BCM programming, it indicates that the Immobilizer Learn procedure was not completed correctly. You will need to repeat the Immobilizer Learn procedure (Steps 3 & 4).
Step 3: Immobilizer Learn – Deleting Existing Keys (Optional)
- Note: This step is relevant if you want to delete existing keys or transponders, rendering them inoperable. This can be useful for security if a key fob is lost or stolen. Skip this step if you do not want to delete existing keys.
- Memory Seats Note: Deleting existing keys allows new transponders to correspond with memory seat locations if your vehicle is equipped with memory seats. If your vehicle is NOT equipped with memory seats, skip this entire step.
- Select Immobilizer Learn (Delete): In SPS, navigate back to the “Supported Controllers” screen and select “IMMO Immobilizer Learn – Setup.” On the next screen, choose “Program Transponder or Remote Key (Delete).”
- Delete Keys: Follow the on-screen instructions in SPS to delete existing keys and remotes.
- Exit Immobilizer Learn Mode: Once the deletion process is complete, follow the SPS instructions to exit the Immobilizer learn mode. Repeat this step to delete any additional remotes if needed.
Step 4: Immobilizer Learn – Adding New Keys
- Select Immobilizer Learn (Add): In SPS, navigate to “IMMO Immobilizer Learn – Setup” again. This time, select “Program Transponder or Remote Key (Add).”
- Add New Keys: Follow the on-screen instructions to add your new transponder or remote keys.
- Complete Immobilizer Learn: When the Immobilizer Learn process is complete, press the “Unlock” button on the new keyless entry transmitter. This action allows the transmitter to exit the Immobilizer Learn mode. Repeat this step to add any additional remotes you are programming.
Step 5: BCM Setup
- Select BCM Setup: Return to the “Supported Controllers” screen and select “BCM Body Control Module – Setup.” Follow the on-screen instructions.
