Post-Installation Procedures
While this module is designed for a simple installation, some vehicles may require additional steps to sync with other onboard systems. Please be aware of the following possibilities:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and more.
Is this BCM difficult to install?
The physical installation is straightforward. The BCM is typically located under the steering column. Basic hand tools are all that’s required to swap the module. Since we program it beforehand, you avoid a trip to the dealer for software flashing.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will use this to program the module specifically for your vehicle’s configuration before shipping.
Will this fix my ‘Security’ light issue?
Yes, a faulty BCM is the most common cause of a persistent ‘Security’ light and a no-start condition on these GM trucks. Replacing it with our pre-programmed module is the correct fix for this issue.
What if my airbag light comes on after installation?
This is not uncommon. It simply means the new BCM needs to be electronically introduced to the airbag system (SDM). A qualified mechanic with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old part?
No. There is no core charge for this part. You can keep your original module.
