Restore Control and End Electrical Frustration in Your GM Truck
If you’re dealing with bizarre electrical issues in your 2002 GMC Yukon or a similar GM truck/SUV, you know how maddening it can be. Flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or even a no-start condition can all point to one culprit: a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can wreak havoc on your daily drive. This isn’t just an inconvenience; it can affect vehicle safety and security.
This is your direct, reliable solution. We offer a fully tested Body Control Module, part number 15095334, that arrives at your door pre-programmed for your specific vehicle. Forget expensive dealership visits and the hassle of finding a shop with the right tools. Simply provide us with your Vehicle Identification Number (VIN) at checkout, and our technicians will flash the module with the latest GM software updates. This ensures seamless integration and restores your vehicle’s functions to factory specifications. This is the most efficient way to get your truck back to 100%.
From the Diagnostic Bay
A customer brought in a 2002 Sierra 2500 last month with a classic parasitic draw. The battery would be dead every two or three days. He’d already replaced the battery and the alternator, but the problem persisted. The interior dome lights would also flicker randomly, even when the truck was off. After hooking up the scan tool, I noticed communication errors with several modules. Instead of chasing wires for hours, I went straight to the BCM. A failing BCM often keeps other modules ‘awake,’ causing a constant drain. We swapped in a pre-programmed module just like this one, and the draw vanished instantly. It’s a common failure point I’ve seen on hundreds of these GMT800 platform trucks, and this 2002 Yukon BCM is the definitive fix.
Is Your GM Truck or SUV Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ The horn honking randomly or the alarm sounding without reason.
- ✔ Dashboard warning lights (like the airbag light) appearing due to communication loss.
- ✔ Inconsistent or failed operation of the radio and instrument cluster gauges.
A Straightforward Guide to Installation
Installing your new BCM is a manageable job for a DIYer with basic tools. While the exact location varies slightly by model, the process is generally similar.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most 2002 GM trucks and full-size SUVs (like the Yukon, Tahoe, Silverado, Sierra), the BCM is located under the driver’s side of the dashboard, near the steering column. On vans (Astro, Safari) and S-series trucks (Blazer, S10), it’s often behind the center dash area.
- Remove Trim Panels: You may need to remove the lower dash knee bolster or other plastic trim panels to gain access. These are typically held by a few screws or clips.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in place of the old one. Securely plug in all the electrical connectors, ensuring they click into place.
- Reconnect and Test: Reinstall any trim panels you removed and reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, etc.
Important Post-Installation Steps
After installing your new 2002 Yukon BCM, a couple of final procedures are necessary to ensure full system functionality and safety. These steps require a professional-grade scan tool.
- Airbag System Reset: To clear the airbag warning light, the ‘Setup SDM Primary Key in BCM’ procedure must be performed. This re-establishes communication between the new BCM and the Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Sensor (BPPS) Relearn: Some vehicles may require a recalibration of the brake pedal position sensor. This is crucial for proper brake light operation and stability control functions.
If you are not comfortable performing these procedures, we strongly recommend seeking assistance from a qualified professional mechanic.

Frequently Asked Questions
Do I need to program this BCM?
No. This is the biggest benefit of our service. We program the module to your vehicle’s VIN before shipping, so it’s ready for installation right out of the box, saving you a trip to the dealer.
Where is the BCM located on my 2002 Yukon?
On the 2002 GMC Yukon and similar full-size trucks/SUVs, the BCM is found under the driver’s side dashboard, typically attached to a bracket near the steering column.
What information do you need from me?
After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). This is essential for us to program the BCM correctly for your specific vehicle options.
Will this fix my security light and no-start problem?
Yes, in most cases. A faulty BCM is a very common cause of issues with the Passlock anti-theft system on these GM vehicles, which can prevent the engine from starting. This programmed module will restore that functionality.
What if my original part number is not 15095334?
This module is a fully compatible replacement for several part numbers, including 15063578, 15081796, 19208537, DKAK, and DPNU. As long as your vehicle is on the fitment list, this part will work correctly.
What tools are needed for the post-installation procedures?
The airbag key setup and brake pedal relearn require a bidirectional scan tool capable of performing these specific manufacturer functions, such as a GM Tech 2, Snap-on, Autel, or similar professional-grade diagnostic tool.
