Is Your GM Truck Experiencing Strange Electrical Problems?
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. It manages everything from your power windows and locks to the interior lights, security system, and warning chimes. When the BCM starts to fail, it can cause a wide range of confusing and frustrating symptoms that can be difficult to diagnose. Instead of chasing down individual electrical gremlins, the root cause is often a faulty BCM.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following, a failing BCM could be the culprit:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights or exterior lights staying on or not turning on at all.
- ✔ The anti-theft or security system engaging randomly, causing a no-start condition.
- ✔ Horn honking unexpectedly or not working.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Complete loss of power to various electronic accessories.
A Simple, Programmed Solution for Your 2002 Tahoe Body Control Module
This isn’t just a replacement part; it’s a complete solution. We take the guesswork out of the repair by pre-programming this module to your vehicle’s specific VIN. This ensures compatibility and proper function right out of the box. Simply provide us with your VIN during checkout, and we’ll flash the unit with the latest GM software updates before shipping it to you. This eliminates the need for an expensive trip to the dealership for programming.
Important Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure all systems communicate correctly.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation.
We believe in making your repair as easy as possible, which is why there is no core charge for this part. You can keep your old module.

Frequently Asked Questions
How does the VIN programming work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians then use this information to load the correct GM-certified software and vehicle-specific calibration onto the module before we ship it.
Where is the BCM located on my vehicle?
On most 2002 GM full-size trucks and SUVs like the Tahoe, Silverado, and Sierra, the BCM is located under the driver’s side of the dashboard, near the steering column. On vans like the Astro and Safari, it’s typically behind the center dash area.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original part, which can be helpful for reference or if you ever need to revert to the original module.
What tools are needed for the installation?
Installation typically requires basic hand tools, such as a socket set and screwdrivers, to remove the lower dash panels and unbolt the module. No special tools are needed for the physical replacement.
What happens 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 the airbag system’s SDM. A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
