Is Your 2002 GM Truck or SUV Experiencing Electrical Gremlins?
If you’re dealing with frustrating and unpredictable electrical problems in your 2002 Yukon, Tahoe, Suburban, or Escalade, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, managing everything from power windows and locks to interior lighting and the security system. When it starts to fail, it can cause a cascade of confusing issues that are difficult to diagnose.
This is a direct-replacement, VIN-programmed Body Control Module that restores full functionality to your vehicle. We take the guesswork out of the repair by pre-programming the unit with the latest GM software specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and we’ll ship a module that’s ready for installation, getting you back on the road quickly and safely.
We had a 2002 Chevy Avalanche come into the shop with a classic BCM failure symptom: the dome lights wouldn’t turn off, no matter what. The owner had been disconnecting his battery every night to keep it from draining. After confirming power and grounds were good, we pinpointed the BCM. Instead of a costly trip to the dealer for programming, we installed one of these pre-flashed units. The moment it was connected and the battery was hooked back up, the lights functioned perfectly. It’s a simple solution to a problem that can make a vehicle nearly unusable.
Common Symptoms of a Failing 2002 Yukon Body Control Module
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The security system engaging randomly or the horn honking without reason.
- ✔ Inaccurate or non-functional gauges on the instrument cluster.
- ✔ False warning messages like “Service 4WD” or “Security” on the driver information center.
- ✔ A/C and heater blower motor controls not responding correctly.
- ✔ The vehicle failing to recognize the key fob for remote entry.
Installation and Post-Install Requirements
This module is designed for a straightforward installation, typically located under the steering column. Because we program it to your VIN, many of the complex dealer-level procedures are eliminated. However, on these specific GM platforms, a couple of simple relearn procedures may be necessary after the new module is installed.
- No Core Charge: You are not required to return your old BCM. Keep your original part.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a capable scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be needed to ensure the brake lights and traction control system function as intended.
Disclaimer: Specific procedures can vary slightly by vehicle model and options. We always recommend consulting a factory service manual or a qualified automotive technician for guidance.

Frequently Asked Questions
Do I need to program this module?
No. We handle all the programming for you before shipment. Just provide your vehicle’s VIN during or after checkout, and it will arrive ready to be installed.
Where is the BCM located on a 2002 Yukon or Tahoe?
The Body Control Module is typically located in the driver’s cabin, underneath the steering column and dashboard assembly.
What if my airbag light is on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this a simple plug-and-play installation?
For the most part, yes. It’s physically plug-and-play, and since it’s pre-programmed, it avoids a trip to the dealer. However, as noted, minor relearn procedures for the airbag or brake systems may be required depending on your specific vehicle.
Do I have to send my old BCM back?
No. This part is sold without a core charge, so you can keep your original module.
How do I give you my VIN?
After you complete your purchase, you will receive instructions on how to send us your VIN. We cannot program and ship your module until we receive this information.
