Restore Full Electronic Functionality to Your GM Vehicle
Are you battling a storm of bizarre electrical problems in your vehicle? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or warning lights that won’t go away can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can create chaos. This replacement Body Control Module is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a straightforward installation.
From the Diagnostic Bay
We once had a 2012 Acadia come in with a laundry list of complaints. The radio would turn off randomly, the driver’s side window wouldn’t go down, and the key fob only worked intermittently. The owner had already replaced the battery and checked fuses with no luck. A full diagnostic scan pointed towards communication errors with the BCM. Instead of chasing individual component failures, we replaced the BCM with a VIN-programmed unit. Instantly, all the seemingly unrelated electrical gremlins vanished. It’s a classic case of the BCM being the root cause of widespread electronic issues.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on or not turning on).
- ✔ Malfunctioning security system or keyless entry.
- ✔ Inoperative dashboard gauges or warning lights that are always on.
- ✔ Problems with the heating and A/C blower motor controls.
- ✔ Communication errors with other vehicle modules, leading to various diagnostic trouble codes (DTCs).

Installation and Post-Install Considerations
While this module is designed for a direct fit, some vehicles may require simple post-installation relearn procedures. These are not always necessary but are important to be aware of:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and traction control function.
There is no core charge for this module. You can keep your original part.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide variety of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and security systems.
How does the VIN programming work?
After you place your order, you provide us with your vehicle’s 17-digit VIN. We use this number to flash the BCM with the exact software and settings your vehicle had when it left the factory, plus any new updates from GM. This makes installation much simpler.
Is this part difficult to install?
For someone with moderate mechanical skill, the physical installation is typically straightforward, involving disconnecting the battery and swapping the module. The main benefit of our service is that the complex programming is already done, eliminating the need for expensive dealer tools for that step.
Do I need to send my old part back?
No, there is no core charge on this BCM. You can keep your original module.
What if my airbag light comes on after I install the new BCM?
This can happen on certain models. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade diagnostic tool to resolve this.
