Is Your GM Truck or Van Plagued by Electrical Gremlins?
Are strange electrical problems driving you crazy? If your S10, Silverado, or Astro is suffering from flickering lights, dead power windows, a faulty security system, or intermittent starting issues, you’re not alone. These are classic, frustrating signs of a failing Body Control Module (BCM). This central computer manages your vehicle’s body electronics, and when it fails, it can make your trusted vehicle feel unreliable. The good news is the solution is simpler and more affordable than a trip to the dealer.
Common Symptoms & Your Direct-Fit Solution
A failing BCM can cause a wide range of confusing symptoms. You might be experiencing:
- Power windows, door locks, or mirrors working intermittently or not at all.
- Interior dome lights or exterior lights staying on or not turning on.
- The security light flashing and preventing the engine from starting (Passlock issues).
- Erratic or non-functional dashboard gauges.
- False warning lights appearing on the instrument cluster.

A Mechanic’s Note on BCM Programming
As a technician, I’ve seen countless DIYers get stuck after installing a used BCM from a junkyard. The vehicle won’t start, or new problems appear. That’s because the BCM is the ‘brain’ for your vehicle’s body electronics and security system; it’s married to the original vehicle’s VIN. Our pre-programming service is the essential step that makes this a successful repair, not another headache. We ensure the GM 15063578 Body Control Module communicates perfectly with your truck’s other systems right out of the box, just like the factory intended.
Important Post-Installation Procedures
While this module is programmed for your vehicle, some systems may require a simple sync procedure after installation. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your vehicle’s existing airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light function and traction control system performance.
Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) is essential for us to program the BCM correctly. It allows us to load the specific software and settings for your vehicle’s exact options, ensuring all features work correctly and the security system recognizes the new module.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is typically straightforward. The BCM is usually located under the dashboard. However, as noted, some post-installation electronic procedures like an airbag sync may require a professional-grade scan tool.
What does a Body Control Module (BCM) do?
The BCM is a computer that acts as a central hub for your vehicle’s body electronics. It controls functions not related to the engine, such as power windows, power locks, interior and exterior lighting, the anti-theft system, and dashboard warning lights.
What happens if my airbag light is on after installation?
If the airbag light illuminates, it means the new BCM needs to be electronically introduced to the vehicle’s Safety Data Module (SDM). A repair shop with a capable diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Do I need to send my old part back?
No. This BCM is sold with no core charge. You can keep your original part, which saves you the time, cost, and hassle of returning a core.
