Is your GM truck or van suffering from baffling electrical problems?
If you’re dealing with flickering lights, power windows with a mind of their own, or a security system that prevents your vehicle from starting, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and seemingly unrelated issues. This VIN-programmed BCM is the reliable, straightforward solution to restore your vehicle’s proper function.
Expert Pro Tip: Before condemning your BCM, always perform a thorough check of all related fuses, relays, and especially the main body ground connections. A loose or corroded ground under the dash or on the frame can mimic BCM failure and is a much simpler and less expensive fix. A quick check can save you time and money.
Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors not working correctly or at all.
- ✔ The security or anti-theft system acting up, potentially causing a no-start condition.
- ✔ Inconsistent or dead gauges on your instrument cluster.
- ✔ The radio or climate control system behaving erratically.
- ✔ “Service Vehicle Soon” or other warning messages appearing on the dash.

We flash it with the latest GM-released software updates, which can resolve issues that were present even in the original factory programming.
Installation and Required Procedures
While this module is designed for a straightforward installation, some vehicles may require additional steps after the new BCM is installed. These are known as ‘relearn’ or ‘synchronization’ procedures. Common requirements for this platform include:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light operation and stability control function, a brake pedal position sensor recalibration may be necessary on certain models.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions, such as power windows, locks, lights, security system, wipers, and interior accessories.
Is this BCM truly plug-and-play?
Because we program it to your VIN, it is as close to plug-and-play as possible. However, as noted above, some vehicles may require additional relearn procedures for systems like the airbags or brakes, which require a professional diagnostic tool.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or reply to your order confirmation email. We cannot ship the module until we receive your VIN.
What if my airbag light is on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
