Restore Your Truck’s Electrical System with a VIN-Programmed BCM
Are you battling frustrating electrical problems in your GM truck or van? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often 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 intermittent symptoms. This replacement Body Control Module, part number 15198115, is the definitive solution to get your vehicle back in perfect working order.
The Easiest Way to Replace Your BCM
Forget expensive dealership visits and the hassle of finding a shop to program a new module. We handle the programming for you before we ship. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash this BCM with the latest official GM software specific to your truck or van. This ensures that when the part arrives, it’s ready for a straightforward installation, saving you time, money, and headaches. This is the most reliable way to replace your faulty 2003-2007 Silverado BCM and restore all electronic functions.
From the Diagnostic Bay
We had a 2006 Sierra 2500 come into the shop with a classic BCM failure symptom: the dome lights and cargo light would not turn off, no matter what. The owner had already replaced the battery twice, thinking it was a parasitic draw he couldn’t find. After a quick diagnostic scan pointed to the BCM, we ordered a VIN-programmed unit. The physical swap under the steering column took less than 20 minutes. As soon as the battery was reconnected, all the lights operated correctly. The customer was thrilled to have a simple, fast solution without a multi-day stay at a dealership.
Common 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.
- ✔ The security system or keyless entry failing or acting unpredictably.
- ✔ Horn sounding unexpectedly or not working at all.
- ✔ Wipers behaving erratically (e.g., won’t turn off).
- ✔ Warning lights on the dashboard, such as the airbag or brake light.
- ✔ Communication errors with other vehicle modules (DTC U-codes).
Installation and Post-Install Considerations
Physically installing the BCM is typically a simple process, as it’s located under the steering column on most trucks or in the center dash on vans. Once installed, your vehicle should start and run. However, due to the complexity of modern vehicle systems, a couple of additional steps may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a capable scan tool. This syncs the new BCM with your vehicle’s existing airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and more.
Is this BCM really plug-and-play?
Yes, it is. We program the module to your vehicle’s specific VIN before shipping. This means it’s ready for installation right out of the box, with no need for additional dealer programming for the module itself to function. Some minor relearn procedures may be necessary post-installation.
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 must have your VIN to program the module before we can ship your order.
What if my airbag light is on after I install the new BCM?
This can happen. It means the new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). A qualified technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
