Restore Full Electrical Function to Your GM Truck
Are you battling frustrating electrical gremlins in your 2002 GM truck or SUV? Issues like flickering lights, malfunctioning power windows and locks, a persistent security light, or even a no-start condition often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. This replacement Body Control Module is the definitive solution, arriving pre-programmed with the latest GM software updates specifically for your vehicle’s VIN.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely cause:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security or anti-theft light stays illuminated, preventing the engine from starting.
- ✔ Inconsistent or non-working dashboard gauges.
- ✔ The horn honking unexpectedly or not working when pressed.
- ✔ Communication errors with diagnostic scan tools.

Post-Installation Procedures
While this module is delivered ready for installation, some vehicles may require additional steps to ensure all systems communicate correctly. 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 your vehicle’s existing airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and to satisfy the traction control system.
Note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does the BCM actually do?
The Body Control Module (BCM) is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and more.
Is this part difficult to install?
The physical installation is straightforward for someone with basic mechanical skills, as the BCM is typically located under the steering column. Since we pre-program the module to your VIN, you avoid the most complex step, which is software flashing. However, some post-install relearn procedures may be required.
What do I need to do after I place my order?
After you complete your purchase, you must provide us with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
Why is a VIN-programmed module better?
Programming the module to your specific VIN ensures it has the correct software and settings for your vehicle’s options. This provides a more seamless installation, better performance, and access to the latest software updates from GM, which can resolve issues the original software may have had.
What if my airbag light comes on after I install it?
This can happen. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A mechanic with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the components and turn off the light.
