Restore Full Electrical Control to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your truck? Flickering lights, unresponsive power windows, a security system that has a mind of its own, or strange dash warnings can all point to a failing Body Control Module (BCM). These issues aren’t just an annoyance; they compromise your vehicle’s reliability and your peace of mind. Stop chasing symptoms and replace the core component with our professionally programmed BCM, designed to get your vehicle back to factory-spec performance quickly and easily.
Common Symptoms & Your Solution
A faulty BCM can cause a wide range of confusing electrical problems. If you’re experiencing any of the following, this module is the definitive solution:
- Intermittent or non-working power windows, door locks, or interior lights.
- The security or anti-theft light stays on, preventing the engine from starting.
- Erratic gauge cluster behavior or warning lights that come and go.
- Communication error codes (U-codes) when scanned with a diagnostic tool.
- HVAC controls not responding correctly.
This programmed 15063578 BCM arrives ready for installation. We use your vehicle’s VIN to flash the module with the latest, most stable software updates from GM, ensuring it communicates perfectly with your truck’s existing systems right out of the box.

From the Technician’s Bench
In my 20+ years of working on these GM trucks and SUVs, I’ve seen countless BCM failures. They are the central hub for the vehicle’s body electronics, and after decades of heat cycles and vibrations, the internal circuit boards and solder joints can develop micro-fractures, leading to the unpredictable issues you’re likely seeing. Many owners try a used BCM from a salvage yard, only to find out the dealership charges a fortune to program it—if they’ll even do it. Our solution provides a fully updated and correctly configured programmed 15063578 BCM, giving you a more reliable and cost-effective repair than sourcing and programming a used part.
Important Post-Installation Information
While this module is programmed for a straightforward installation, some vehicles may require one or two simple relearn procedures to sync all systems perfectly. These can typically be performed by a local repair shop with a capable diagnostic tool.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be necessary on some models to ensure proper brake light and traction control function.
Note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is a computer that acts as the central command center for your vehicle’s body electronics. It controls functions not related to the engine, such as power windows, door locks, interior and exterior lighting, the security system, and the climate controls.
Is this module difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. On these models, it’s usually located under the steering column or in the center dash. Since our programmed 15063578 BCM is flashed to your VIN, you avoid the complex programming steps required with a new or used module from another source.
What happens after I place my order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. We cannot program and ship the module without it. Once we have your VIN, our technicians will program the BCM with the latest GM software specific to your vehicle and ship it out to you.
Where can I find my VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Do I need to send my old BCM back?
No. This product comes with no core charge, so you are not required to return your original module. This simplifies the process and gets you back on the road faster.
