Is your 2002 GMC Sierra, Chevy Silverado, or other GM truck plagued by bizarre electrical issues? Problems like flickering lights, malfunctioning power windows and locks, or a persistent ‘Security’ light are often signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and seemingly unrelated symptoms. Restore order and reliability with this direct-fit, pre-programmed Body Control Module.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ The vehicle’s anti-theft system engaging randomly, causing a no-start condition.
- ✔ Windshield wipers activating on their own or not working when needed.
- ✔ Erratic gauge behavior or warning lights on the instrument cluster.
- ✔ Climate control or radio functions are unresponsive.
- ✔ False warnings, such as a ‘door ajar’ light when all doors are closed.

Installation and Required Procedures
While this module is designed for straightforward installation, some vehicles may require additional steps after the part is installed to ensure all systems communicate correctly. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine-related functions, such as power windows, locks, lights, wipers, security system, and interior accessories.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the correct software and settings for your specific vehicle’s features and options. This ensures the module works correctly right out of the box.
Is this BCM difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. It’s often located under the steering column or in the center dash. However, as noted, some vehicles may require a post-installation relearn procedure with a diagnostic tool.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What happens if my airbag light is on after installation?
This indicates that the new BCM needs to be synchronized with your vehicle’s airbag system (SDM). A technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
