Is Your GM Vehicle Plagued with Baffling Electrical Problems?
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. It manages everything from your interior and exterior lights to your power windows, door locks, and security system. When the BCM starts to fail, it can cause a cascade of strange, intermittent, and frustrating issues that can be difficult to diagnose. You might find your battery draining overnight, your horn honking randomly, or your dashboard lighting up like a Christmas tree for no reason. These aren’t just annoyances; they can compromise your vehicle’s safety and reliability.
Common Symptoms of a Failing BCM:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, locks, or mirrors working intermittently or not at all.
- ✔ The security system engaging randomly or preventing the car from starting.
- ✔ Unexplained parasitic battery drain that kills your battery overnight.
- ✔ Dashboard warning lights appearing and disappearing without cause.
- ✔ Issues with the radio, climate control, or other interior accessories.
- ✔ Inability to communicate with the module using a diagnostic scan tool.

Post-Installation Procedures
While this module is designed for plug-and-play installation, some vehicles may require a simple relearn procedure for specific systems after the BCM is installed. These can often be performed with a capable bidirectional scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Please consult a factory service manual or a qualified technician for guidance specific to your vehicle.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like lights, power windows, security systems, door locks, and wipers.
Does this module need to be programmed?
No, you do not need to take it to a dealer for programming. We handle that for you! Just provide your vehicle’s VIN when you order, and we will program the module with the latest GM software before shipping it.
How do I find and provide my 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 of the dashboard visible through the windshield. You will be prompted to provide it after you complete your purchase.
What if the airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system (SDM). A professional technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module, so there’s no need to worry about the cost or hassle of sending it back.
