Restore Your Vehicle’s Electronic Functions
Are you battling frustrating electrical gremlins in your GM vehicle? Intermittent power windows, erratic lights, or a security system with a mind of its own are common signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it falters, it can cause a cascade of confusing and disruptive issues. This replacement BCM is the definitive solution to restore full functionality and peace of mind, arriving pre-programmed for your specific vehicle.
The Hassle-Free Solution for BCM Failure
Replacing a BCM traditionally means a trip to the dealership for expensive programming. We eliminate that step. By providing your vehicle’s VIN during checkout, you receive a module that is flashed with the latest GM software updates and is ready for installation right out of the box. This saves you time, money, and the headache of coordinating with a service center. This is a direct-fit, reliable replacement for a faulty original module, designed to get your van, truck, or SUV back to operating as it should.
From the Diagnostic Bay
We had a 2011 Express work van come in that was a complete mystery. The driver reported the dome lights would stay on, the radio would randomly shut off, and the power locks were unresponsive. Initial checks on fuses and wiring showed nothing. After connecting our diagnostic tool, we saw multiple communication loss codes pointing to the BCM. Instead of a lengthy and costly diagnostic and programming session at the dealer, the owner opted for one of our VIN-programmed modules. The installation took less than an hour, and instantly, all the strange electrical issues were gone. It turned a potentially multi-day repair into a simple, straightforward fix.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Power windows, mirrors, or door locks working intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ Vehicle security system engaging randomly or showing a service warning.
- ✔ Instrument panel gauges behaving erratically or warning lights appearing for no reason.
- ✔ Remote keyless entry failing to respond.
- ✔ Communication errors with other vehicle computers, flagged by a diagnostic scan tool.
Post-Installation Procedures
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure all systems communicate correctly. Please be aware of the following potential requirements:
- Airbag System Sync: If the 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 relearn may be necessary to ensure correct operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
How does the VIN programming work?
After you complete your purchase, you provide us with your vehicle’s 17-digit VIN. We use this number to load the exact software and calibration files from GM for your specific vehicle onto the module before we ship it to you.
Is this a plug-and-play installation?
For most vehicles, yes. The module is programmed to work upon installation. However, as noted, some models may require an airbag system sync or brake pedal position relearn, which requires a professional diagnostic tool.
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 my airbag light comes on after I install it?
This indicates that the BCM and the airbag system (SDM) need to be synchronized. A technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Where is the BCM located on my 2008-2012 Express Van?
On the 2008-2012 Express and Savana vans, the Body Control Module is typically located in the center dash area.
Will this fix all my electrical problems?
If a faulty BCM has been properly diagnosed as the cause of your issues, this part is the correct solution. It’s important to ensure the BCM is the root cause and not a wiring or component-specific problem.
