Is Your 2002 GM Truck or SUV Experiencing Bizarre Electrical Problems?
If you’re dealing with flickering lights, malfunctioning power windows and locks, a persistent security light, or a no-start condition, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and seemingly unrelated issues. Don’t let electrical gremlins keep your truck off the road. This pre-programmed BCM is the reliable, straightforward solution you need.
Common Symptoms of a Failing BCM
- ✔ Power windows, mirrors, or door locks working intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The anti-theft or security light is illuminated, preventing the engine from starting.
- ✔ Erratic behavior from the radio or instrument cluster gauges.
- ✔ Windshield wipers activating on their own or not working when commanded.
- ✔ False warnings on the driver information center, such as “Service Vehicle Soon.”

This means it arrives ready for installation, loaded with the latest software updates from GM.

Installation and Post-Install Notes
Installation is typically straightforward, as the BCM is located under the steering column or in the center dash area. Once installed, most functions will be immediately restored. However, please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on 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 module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any part 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 various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these functions.
Is this BCM difficult to install?
For most DIY mechanics, the installation is manageable. The BCM is typically located under the driver’s side dashboard. The main benefit of our module is that it’s pre-programmed, which eliminates the most difficult step of the process.
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 after I place my order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. We will then program the BCM with the latest GM software specific to your truck before shipping it to you.
What if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
