End the Electrical Gremlins in Your 2002 GM Truck or SUV
Are you dealing with bizarre electrical issues in your trusty 2002 Tahoe, Suburban, or Yukon? From power windows that have a mind of their own and flickering dashboard lights to a security system that won’t cooperate, a failing Body Control Module (BCM) can be incredibly frustrating. It’s the central command for your vehicle’s body electronics, and when it goes, it takes comfort, convenience, and reliability with it. Stop chasing symptoms and get the definitive solution with our pre-programmed 2002 Tahoe Body Control Module.
Common Symptoms & Your Direct Solution
If you’re experiencing any of the following, a faulty BCM is the most likely culprit:
- Erratic or non-functional power windows, door locks, and mirrors
- Interior dome lights or exterior lights staying on or not working at all
- The security light flashing, preventing the vehicle from starting (Passlock issues)
- Inaccurate or dead gauges on the instrument cluster
- Warning lights appearing for no reason (ABS, Airbag, etc.)
- Diagnostic trouble codes (DTCs) related to communication errors (U-codes)
This isn’t just a replacement part; it’s a complete, hassle-free repair. We flash the module with the latest GM software updates and program it specifically to your vehicle’s VIN before we ship it. This means you can bypass the expensive trip to the dealership for programming. This is the straightforward fix you need to get your truck back to 100%.

Expert Technician’s Insight: As a tech with over 20 years in the bay, I’ve seen hundreds of these GMT800-platform trucks. Their BCMs are notorious for failing due to age and heat cycles, which cause internal solder joints to crack. This leads to the confusing, intermittent problems you’re likely facing. A pre-programmed 2002 Tahoe Body Control Module is the single most efficient repair. It eliminates diagnostic guesswork and saves you hundreds compared to the dealer’s parts and labor costs for programming a blank module.

Important Post-Installation Information
While this module is designed for a simple installation, some vehicles may require one of the following procedures to be performed with a professional scan tool after the BCM is installed:
- Airbag System Sync: If your airbag warning light is on after installation, the ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the airbag system to the new BCM.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be needed on some models to ensure proper brake light and traction control operation.
Frequently Asked Questions
How do I provide you with my VIN?
After you complete your purchase, you can either add your VIN to the order notes or simply reply to your order confirmation email with the 17-digit VIN. We cannot ship your part until we receive it.
Is this a difficult part to install myself?
For someone with basic automotive skills, this is a very manageable job. The BCM is located under the driver’s side dashboard, near the steering column. The key is that our pre-programming saves you the most difficult step, which is the dealer-level computer setup.
Will this fix my ‘Security’ light and no-start problem?
Yes, a flashing ‘Security’ light is one of the most common symptoms of a failed BCM on these 2002 GM trucks and SUVs. This programmed module is designed to resolve that specific issue by correctly syncing with your vehicle’s Passlock anti-theft system.
What happens if my 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 vehicle’s airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to turn the light off.
Do I need to send my old part back?
No. This purchase has no core charge. You can keep or dispose of your original module at your convenience.
