Is your GM truck or SUV experiencing bizarre electrical problems? You’re not alone.
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. From flickering lights and malfunctioning power windows to a vehicle that won’t start, a faulty BCM can make your reliable truck feel possessed. This replacement Body Control Module is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a straightforward installation.
From the Diagnostic Bay
We had a 2002 Silverado 2500 in the shop with a list of complaints from the owner. The dome lights would stay on, the radio display would flicker, and the power locks worked intermittently. The owner was convinced he had multiple separate problems. After checking the basics, we connected our diagnostic tool and found multiple communication errors pointing back to one source. By monitoring data streams, we confirmed the BCM was failing. We installed a VIN-programmed module just like this one, and every single electrical issue was resolved instantly. It’s a perfect example of how one component can be the root of many problems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ The security system acting up, causing no-start conditions or random alarm activation.
- ✔ False warning messages appearing on the driver information center (e.g., “Service 4WD System”).
- ✔ Climate control or A/C system behaving unpredictably.
- ✔ The horn honking without input or not working when pressed.

Post-Installation Procedures
While this module is designed for easy installation, some vehicles may require additional steps to sync all systems perfectly. Please be aware of the following potential procedures:
- 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 recalibration may be necessary to ensure correct brake light operation and traction control functionality.
Always consult a factory service manual or a qualified technician if you are unsure about any step of the installation process.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, security system, and climate controls.
Do I need to program this module?
No. We program the module to your vehicle’s VIN before shipping it to you. It will arrive ready to be installed, saving you a trip to the dealership and additional programming fees.
What information do you need from me?
After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). This is essential for us to load the correct software for your vehicle’s specific options.
What happens if my airbag light is on after installation?
This can happen on some models. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without needing to send it back to us.
