Are you battling frustrating electrical issues in your GM truck or SUV? Flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own are common signs of a failing Body Control Module (BCM). This vital component acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing problems. Restore full functionality and peace of mind with our pre-programmed BCM, a direct-fit replacement for your original module.
This isn’t just a replacement part; it’s a complete solution. We program the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures seamless integration with your truck’s existing systems and loads the very latest software updates from GM. This often corrects underlying factory bugs and improves overall performance, providing a fix that is often better than the original. Simply provide your VIN during checkout, and we handle the rest.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights or exterior lights staying on or not turning on at all.
- ✔ The security system or anti-theft light flashing, preventing the vehicle from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Dashboard warning lights appearing for various systems with no clear cause.
- ✔ Communication errors when a mechanic tries to scan the vehicle’s computer systems.

Installation and Post-Install Notes
Installation is typically straightforward, involving basic hand tools to access the module (often located under the steering column or in the center dash). After installation, most vehicles will function perfectly. However, please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light operation.
Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
