Restore Full Electrical Function to Your GM Vehicle
Are you battling bizarre electrical problems in your Chevy Express or GMC Savana van? Flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are common 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 range of frustrating and difficult-to-diagnose issues. This replacement module is the definitive solution to restore your vehicle’s systems to perfect working order.
From the Diagnostic Bay
We had a contractor’s 2011 Express 2500 work van in the shop that was driving him crazy. The dome lights would stay on, the radio would randomly shut off, and sometimes the power door locks wouldn’t respond. He had replaced the battery and checked fuses, but the gremlins persisted. After hooking up our diagnostic scanner, we saw communication errors pointing directly to a faulty BCM. We installed a VIN-programmed module, and all the strange issues vanished instantly. It’s a reminder that a single faulty module can wreak havoc on a vehicle’s entire electronic system.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from the instrument cluster, including gauges and warning lights.
- ✔ Malfunctioning interior or exterior lighting.
- ✔ Vehicle security system faults or false alarms.
- ✔ Problems with the heating and A/C controls.
- ✔ In some cases, a no-start condition due to security system communication failure.

Post-Installation Information
While this module is programmed for your vehicle, some systems may require a simple relearn procedure after installation to ensure full communication between all modules. This is a normal part of the repair process.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a professional scan tool. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle the programming for you before we ship the part. Just provide your vehicle’s VIN during or after checkout, and it will arrive ready for installation.
How do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
Is this part difficult to install?
The physical installation is typically straightforward, involving the removal of a few dash panels to access the module. However, as noted, some post-installation electronic relearn procedures may be necessary and require a professional scan tool.
What happens if my airbag light comes on after I install it?
This indicates the new BCM needs to be synced with your vehicle’s airbag system (SDM). A qualified technician can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep or dispose of your original module.
Will this fix my ‘Service Stabilitrak’ or ‘Service Traction Control’ message?
A failing BCM can cause these warnings. While this module may resolve the issue, these messages can also be triggered by other components like wheel speed sensors. Proper diagnosis is always recommended.
