Restore Full Electronic Functionality to Your GM Vehicle
Are you battling frustrating electrical problems in your GM car, truck, or SUV? Issues like flickering lights, malfunctioning power windows and locks, a security system that acts up, or a mysterious battery drain often 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 cause a cascade of confusing and disruptive symptoms. This replacement GM Body Control Module is the definitive solution to restore your vehicle’s performance and your peace of mind.
From the Diagnostic Bay
We had a 2011 Chevy Impala come in with the classic signs of a BCM failure. The customer complained of the radio turning on and off by itself, the dome lights staying on and draining the battery overnight, and the key fob working only intermittently. After confirming power and grounds were good, we diagnosed the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our pre-programmed units. The vehicle was back to normal in under an hour, saving the customer significant time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Vehicle security system faults or alarm sounding unexpectedly.
- ✔ Intermittent or complete failure of dashboard gauges.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ Key fob not responding or remote start failure.
- ✔ ‘Service Stability System’ or other warning messages on the dash.

Important Post-Installation Information
While this module is delivered ready for installation, some vehicles may require minor additional steps, known as relearn procedures, to sync with other vehicle systems. These are typically straightforward and can sometimes be required after any BCM replacement.
- 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 relearn may be necessary to ensure correct brake light operation and to clear any traction control warnings.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
Frequently Asked Questions
Do I need to program this BCM?
No. We handle the programming for you before we ship the part. Just provide your vehicle’s 17-digit VIN at checkout, and it will arrive ready to be installed.
What does the Body Control Module do?
The BCM acts as the brain for your vehicle’s body electronics. It controls functions like power windows, locks, interior/exterior lighting, the security system, key fob functions, and more.
Is this a guaranteed fix for my vehicle’s electrical problems?
A faulty BCM is a very common cause for the symptoms listed. However, you should always perform a proper diagnosis to rule out other potential issues like bad wiring, grounds, or fuses before ordering.
What happens if the airbag light turns on after I install it?
This is a normal security measure on some GM vehicles. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A mechanic with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old part back?
No, there is no core charge for this module. You can keep your original part.
