Restore Full Electronic Function to Your GM Truck or SUV
Are you battling with erratic power windows, flickering interior lights, or a security system that has a mind of its own? These frustrating electrical gremlins in your 2002 GM truck or SUV often point to one central culprit: a failing Body Control Module (BCM). The BCM is the electronic nerve center for your vehicle’s body-related functions, managing everything from your power locks and windows to the interior lighting and anti-theft system. When it fails, it can cause a cascade of seemingly unrelated problems, making your vehicle unreliable and frustrating to drive.
This is your direct-fit solution. This Body Control Module is a precise replacement for your original unit and is compatible with service numbers 15063577, 15081857, 19208544, 15095335, DKAJ, and DPNW. We eliminate the need for expensive dealership visits by pre-programming this module to your vehicle’s exact VIN before it ships. This ensures it integrates seamlessly with your truck’s existing systems, restoring all functions to their original factory performance. Simply provide your VIN after purchase, and we’ll handle the rest.
From the Diagnostic Bay
We had a 2002 Yukon in the shop where the owner was convinced it was haunted. The dome lights would flicker, the horn would honk randomly at night, and the power locks would cycle while driving. After hours of chasing wires, we traced it all back to a BCM with internal corrosion from a leaky windshield seal. A simple swap with a VIN-programmed module like this one solved every single issue in under an hour. It’s amazing how one component can cause so much chaos and how a correctly prepared part can fix it so easily.
Symptoms of a Failing 2002 Suburban Body Control Module
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The vehicle’s security system randomly activating or preventing the engine from starting (Passlock issues).
- ✔ Dashboard warning lights, such as the airbag or brake light, illuminating without a clear cause.
- ✔ Inconsistent or non-functional climate controls or radio.
- ✔ Key fob commands are not being recognized by the vehicle.
Installation and Post-Install Procedures
The BCM is located under the steering column for easy access. While our VIN programming makes this a near plug-and-play installation, some vehicles may require simple post-installation synchronization procedures. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light operation and traction control functionality.
- No Core Charge: We do not require you to return your old part. This saves you the time and expense of shipping a core back.

Frequently Asked Questions
What exactly is VIN programming?
VIN programming involves loading your vehicle’s unique 17-digit Vehicle Identification Number (VIN) and its specific factory options into the BCM. This ensures the module communicates correctly with all other computers in your truck, like the Engine Control Module and instrument cluster. It’s a critical step for proper function.
Is this a plug-and-play part?
Because it comes pre-programmed to your VIN, it is as close to plug-and-play as possible. However, as noted in the description, some vehicles may require an additional sync procedure for the airbag system or brake pedal sensor, which requires a compatible professional scan tool.
How do I provide my VIN after purchase?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s VIN. We cannot ship your order until we receive and validate your VIN, so please provide it promptly to avoid delays.
Do I need a professional mechanic to install this?
Many experienced DIYers can replace a BCM, as it’s typically accessible under the dashboard. However, because a post-install sync procedure may be required with a professional scan tool, we recommend installation by a qualified technician to ensure everything is configured correctly.
Will this fix my security/anti-theft issue?
A faulty BCM is a very common cause of issues with the GM Passlock anti-theft system, often preventing the vehicle from starting. Replacing and programming the BCM is the correct repair for this specific failure.
