An Expert’s Note: As a technician for over 20 years, I’ve seen countless hours wasted chasing what appears to be a bad window switch or a faulty ground wire. More often than not on these early 2000s GM vehicles, the root cause is the BCM. It’s the central hub for all body electronics. Replacing it with a properly programmed unit like this one doesn’t just fix one symptomโit often resolves a half-dozen minor annoyances the owner had learned to live with. It’s one of the most satisfying repairs because it brings the whole vehicle’s interior back to life.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your exact vehicle.
What does the BCM actually control?
The Body Control Module acts as the central computer for your vehicle’s body electronics. This includes power windows, power locks, interior and exterior lights, the security system, wipers, and often parts of the instrument cluster and radio.
Do I have to send my old BCM back?
No. This part is sold with no core charge. You can keep your original module, which can be helpful for comparison or as a backup.
What are the post-installation procedures mentioned?
On some models, after installing the new BCM, a ‘Setup SDM Primary Key in BCM’ procedure may be needed if the airbag light is on. Additionally, a ‘Brake Pedal Position Relearn’ might be required. These are simple procedures for a qualified technician with a professional scan tool.
Is this a difficult part to install myself?
For someone with moderate mechanical experience, the physical replacement is typically straightforward. The BCM is usually located under the steering column or in the center dash area. The key is ensuring any necessary relearn procedures are performed afterward for full system compatibility.
Will this fix my ‘Service 4WD’ light?
While the BCM communicates with many modules, a ‘Service 4WD’ message is more often related to the Transfer Case Control Module (TCCM) or a sensor in the 4×4 system. This 2002 Suburban BCM 15063578 primarily handles body electronics, not drivetrain functions.
