Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are strange electrical problems plaguing your GM truck, van, or SSR? Flickering lights, malfunctioning windows, a dead instrument cluster, or random warning chimes are classic signs of a failing Body Control Module (BCM). This isn’t just an annoyance—it’s a critical failure that can sideline your vehicle and disrupt your work or daily life.

An Expert’s Insight on BCM Replacement
As a technician with over 20 years on the floor, I’ve seen countless hours wasted chasing electrical gremlins that all led back to a failing BCM. Think of the BCM as the vehicle’s central nervous system for everything inside the cabin. It manages everything from your power locks to your interior lights. When it fails, the symptoms can be chaotic. Simply swapping in a used module won’t work on these GM vehicles; it will cause more problems or simply won’t function. The security information is tied to the VIN. That’s why getting a Programmed GM BCM 15747545 that is pre-flashed to your exact vehicle is not just a convenience—it’s the only way to do the job right and ensure a lasting repair.
Post-Installation Procedures
While our programming handles the most critical steps, some vehicles may require a simple relearn procedure after installation to sync with other onboard systems. These can typically be performed by a qualified mechanic with a professional scan tool:
- Airbag System Sync: If the airbag warning light is on after installation, the ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems. This is only required if the light appears.
- 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 requirements can vary. We always recommend consulting a factory service manual for your exact make and model.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine. This includes power windows, locks, lights, security systems, wipers, and more.
Is this BCM difficult to install?
The physical installation is typically straightforward, as the BCM is usually located under the steering column or in the center dash. Since we pre-program the module to your VIN, you eliminate the most difficult step. However, some vehicles may require the post-installation relearn procedures mentioned above.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it. You can usually find your VIN on the driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Will I need to do anything after installation?
In many cases, the module will work immediately. However, as noted in our listing, some vehicles may require an ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ using a professional scan tool to clear warning lights and ensure all systems are communicating correctly.
What happens if I install a BCM that isn’t programmed?
An unprogrammed BCM will not work correctly. It can cause numerous issues, from features not working at all to immobilizing the vehicle due to security system mismatches. Our VIN programming service is essential for a successful repair.
How can I be sure this fits my vehicle?
Please review the detailed fitment list in the description. This module replaces several original part numbers, including 15747545, 15167329, and 15194169. Matching one of these numbers and your vehicle’s year, make, and model ensures compatibility.
