Are you battling frustrating electrical gremlins in your GM truck or van? Issues like flickering lights, malfunctioning power windows and locks, or a persistent “Service Theft System” message are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and seemingly unrelated problems. This replacement BCM is the definitive solution to restore your vehicle’s functionality and peace of mind.
We make the replacement process simple. This module arrives at your door pre-programmed with the latest GM software, specifically flashed to your vehicle’s VIN. This eliminates the need for expensive dealership programming or specialized scan tools for the initial setup. Simply provide your VIN during checkout, and we handle the rest, ensuring a direct-fit, ready-to-install part.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security or anti-theft system acting up, possibly preventing the engine from starting.
- ✔ Instrument cluster gauges behaving erratically or warning lights staying on.
- ✔ Intermittent failure of the radio or climate controls.
- ✔ Unexplained parasitic battery drain that kills your battery overnight.
- ✔ Communication fault codes (U-codes) when scanned with a diagnostic tool.

Installation and Post-Install Procedures
While the core programming is done for you, some vehicles may require simple relearn procedures after installation. These are security handshakes between modules that can sometimes require a professional scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
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 functions. This includes power windows, power locks, interior and exterior lighting, the security system, wipers, and more.
Is this BCM truly plug-and-play?
For most functions, yes. Because we program it to your VIN before shipping, it eliminates the need for the main programming procedure. However, as noted, some vehicles may require additional security relearn procedures for systems like the airbags, which may require a scan tool.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information.
What if my airbag light is on after installation?
This is a normal security measure on some GM vehicles. The new BCM needs to be electronically introduced to the airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I need to return my old BCM?
No. This part is sold with no core charge. You can keep your original module.
