Are you battling frustrating electrical issues in your 2002 GM truck or SUV? Flickering lights, malfunctioning power windows and locks, a persistent security light, or even a no-start condition are common signs of 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 unpredictable problems. This replacement BCM, part number DKAJ, is the definitive solution to restore your vehicle’s proper function and reliability.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We pre-program this module to your vehicle’s specific Vehicle Identification Number (VIN) before shipping. This critical step ensures seamless integration with your truck’s existing systems, eliminating the need for an expensive trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest, sending you a part that’s truly plug-and-play.
Common Symptoms of a Failing BCM

- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Dashboard warning lights flicker or illuminate for no reason.
- ✔ Radio or climate control systems behave unpredictably.

Installation and Post-Install Procedures
Installation is straightforward as the BCM is typically located under the steering column. Once the new module is installed, most functions will be immediately restored. However, in some cases, additional steps may be required:
- Airbag System Sync: If the airbag warning light is illuminated 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 system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor relearn might be necessary.
We make the process easier by offering a no-hassle core policy. There is no core charge, so you can keep your original module. Order today and get your truck’s electronics working like new again.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and climate controls. It’s the main hub for all body electronics.
Is this BCM really plug-and-play?
Yes, for most vehicles. Because we program it to your VIN before shipping, it eliminates the need for dealer programming. In some instances, a simple relearn procedure for the airbag or brake systems may be required, as noted in the description.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we receive and program it with your VIN.
What if my airbag light comes on after installation?
This can happen as the new BCM needs to be synced with the airbag’s Supplemental Deployment Module (SDM). A qualified mechanic with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix the ‘Service 4WD’ message on my dashboard?
A faulty BCM is a very common cause of false ‘Service 4WD’ messages on these GM trucks and SUVs. While not a guarantee for every case, replacing a failing BCM often resolves this issue.
Do I need to send my old BCM back?
No. This part has no core charge, so you are not required to return your original module.
