Are you battling bizarre electrical problems in your GM truck or van? Issues like flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement BCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN with the latest GM software updates.
From the Diagnostic Bay
We had a 2002 GMC Sierra in the shop that was driving the owner crazy. The dome lights and cargo light would stay on intermittently, draining the battery overnight. He’d already replaced the battery and checked all the door jamb switches. After hooking up the scan tool, we saw communication fault codes pointing directly to the BCM. We installed a VIN-programmed module just like this one, and the problem was solved instantly. It’s a common failure point on these trucks, but thankfully, it’s a straightforward fix with the right part.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ The horn sounding unexpectedly or not working at all.
- ✔ Dashboard warning lights appearing without a clear cause.
- ✔ Communication errors with diagnostic scan tools.

Post-Installation Information
After installation, some vehicles may require one or two final synchronization steps. These are simple procedures for any professional technician with a capable diagnostic tool:
- Airbag System Sync: If the airbag warning light is on, a ‘Setup SDM Primary Key in BCM’ procedure is needed 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 and traction control operation.
This module is a direct replacement for the following part numbers: 15063578, 15081796, 15095334, 19208537, DKAK, DPNU
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls functions like power windows, locks, interior/exterior lighting, the security system, and wipers.
Is this BCM truly plug-and-play?
Yes, this BCM is pre-programmed to your vehicle’s VIN before shipping, making the installation process as simple as possible. In some cases, a final sync procedure for the airbag or brake pedal sensor may be needed by a technician.
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 cannot program and ship the module without it.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if the airbag light is on after I install the new BCM?
This is a normal possibility. It simply means the new BCM needs to be electronically introduced to the airbag module. A qualified technician with a GM-compatible scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
