Important Post-Installation Information
While this module is VIN-programmed for a straightforward installation, some vehicles may require additional steps after the part is installed. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine-related electronic functions, such as power windows, locks, lights, security system, wipers, and instrument cluster functions.
Why is my VIN required for this part?
Your VIN is essential because it allows us to program the BCM with the latest GM software specific to your vehicle’s factory-installed options and security configuration. This ensures the module works correctly right out of the box.
Is this part difficult to install?
The physical installation is typically straightforward. The BCM is located under the steering column and involves disconnecting the battery and swapping a few electrical connectors. However, as noted, some post-installation electronic procedures may be required.
What happens if the airbag light comes on after I install it?
If the airbag light appears, it means the new BCM needs to be electronically synced with the vehicle’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key’ procedure using a professional scan tool.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
