Are you battling bizarre electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts up, or an instrument cluster that seems to have a mind of its own? These are classic signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide array of frustrating and difficult-to-diagnose issues. Restore full functionality and peace of mind with our direct-fit, VIN-programmed BCM, part number 15276271.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ False warnings on the instrument cluster (e.g., ‘Service Theft System’).
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ Communication errors with other vehicle modules, leading to a no-start condition.

Installation and Post-Install Notes
While the physical installation is often a straightforward plug-and-play process, some vehicles may require additional steps to ensure all systems communicate correctly. After installing your new Programmed GM BCM, you may need a professional scan tool for two potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is required to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary for proper brake light and traction control operation.
There is no core charge for this part, so you can keep your old module without the hassle of returning it.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security systems, and the instrument cluster.
Do I need to get this BCM programmed by a dealer?
No! That’s the best part. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready to be installed, saving you a trip to the dealership and expensive programming fees.
How do I provide my vehicle’s VIN?
Simply enter your 17-digit VIN in the notes section during checkout. If you forget, we will contact you via email after your purchase to get the necessary information before we program and ship your part.
What if the airbag light is on after I install the module?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to the airbag system. A qualified technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Is this a guaranteed fix for my vehicle’s electrical problems?
While this BCM resolves the vast majority of issues listed, proper vehicle diagnostics are always recommended. Ensure that the BCM is the source of the fault and that wiring, grounds, and other components are in good condition.
