Is Your GM Vehicle Acting Possessed?
Are you dealing with a frustrating array of electrical problems? Perhaps your power windows have a mind of their own, the interior lights flicker randomly, your dash is lit up with warning lights, or the security system prevents the car from starting. These aren’t just annoyances; they are classic signs of a failing Body Control Module (BCM), the central electronic nerve center of your vehicle.
From the Diagnostic Bay
We once had a 2009 Chevy Express van come in that was a complete mystery to its owner. The radio would turn on and off, the door locks would cycle while driving, and the battery would be dead every other morning. The owner had replaced the battery and alternator, but the gremlins persisted. After a quick scan, we pinpointed the BCM. It was sending erratic signals, causing components to activate randomly and creating a parasitic draw. Installing a VIN-programmed BCM like this one solved every single issue instantly, saving the owner from a costly and time-consuming diagnostic nightmare at the dealership.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, and mirrors.
- ✔ Erratic behavior from interior or exterior lights.
- ✔ Malfunctioning windshield wipers or horn.
- ✔ False alarms from the security system or a no-start condition.
- ✔ Warning lights on the dashboard, including airbag or brake system lights.
- ✔ Unexplained battery drain that leaves you stranded.

Post-Installation Information
While our VIN programming handles the majority of the setup, some vehicles may require minor post-installation procedures. These are typically simple and can often be performed by a local shop if needed:
- Airbag System Sync: If the airbag light is illuminated after installation, 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 operation of the brake lights and traction control system.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls your vehicle’s body electronics. This includes power windows, door locks, lights, wipers, security system, and other comfort and convenience features.
How does the VIN programming work?
After you place your order, you provide us with your 17-digit Vehicle Identification Number (VIN). We use this to load the exact software and settings your vehicle had when it left the factory, ensuring all your options work correctly.
Is this part difficult to install?
Installation is typically straightforward. The BCM is usually located under the dashboard on the driver’s or passenger’s side. It involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. However, always consult a service manual for your specific vehicle’s procedure.
Will this fix all of my vehicle’s electrical problems?
This module will correct issues directly caused by a faulty BCM. While the symptoms listed are very common for BCM failure, we always recommend a proper diagnosis to rule out other potential causes like bad wiring or faulty switches.
What if my airbag light comes on after I install it?
This is a known possibility. The new BCM needs to be electronically ‘introduced’ to the airbag system. A repair shop with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Do I need to return my old BCM?
No. This part is sold with no core charge, so you can keep your original module without any extra fees or hassle.
