Restore Full Functionality to Your GM Truck or SUV
If your 2002 Cadillac Escalade, Silverado, or Yukon is plagued by bizarre electrical problems, a failing Body Control Module (BCM) is the most likely culprit. As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating issues, from flickering lights to a no-start condition. This replacement BCM, part number 15095334, is the definitive solution. We take the guesswork and high dealership costs out of the equation by programming the module to your vehicle’s specific VIN before it ships. This ensures a seamless installation and restores your vehicle’s electronics to factory-fresh operation.
From the Diagnostic Bay: The Case of the Haunted Silverado
I remember a 2002 Silverado 1500 that came into my shop with a list of symptoms that sounded like a ghost was in the machine. The dome light wouldn’t turn off, the power locks would cycle on their own, and the radio would sometimes stay on after the key was removed, draining the battery. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a handful of communication codes (U-codes) pointing to the BCM. On these specific GM platforms, the BCM is notorious for internal relay failures and cracked solder joints from years of heat cycles. We installed a VIN-programmed 2002 Escalade BCM (which is compatible) and all the phantom electrical issues vanished instantly. It’s a classic fix for a common problem.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is your solution:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security or anti-theft light is illuminated, preventing the engine from starting.
- ✔ Intermittent operation of the radio or climate controls.
- ✔ False warnings on the instrument cluster (e.g., “Door Ajar”).
- ✔ Diagnostic Trouble Codes (DTCs) related to lost communication, such as U1000, or other BCM-specific faults.
A Straightforward Guide to Installation
Installing your new BCM is a manageable job for a confident DIYer. Since we program it beforehand, you avoid a trip to the dealer for expensive calibration.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On most trucks and SUVs like the 2002 Escalade, Tahoe, and Silverado, the BCM is located under the driver’s side of the dashboard, near the steering column. On vans like the Astro and Safari, it’s typically behind the center dash panel.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount the new, pre-programmed module in place and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock in.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair.
Important Post-Installation Information
In some cases, additional steps may be required after installation to ensure all vehicle systems communicate correctly with the new 2002 Escalade BCM. Please note the following:
- Airbag System Sync: If your airbag warning light is on after installation, a procedure called “Setup SDM Primary Key in BCM” is needed. This requires a professional-grade scan tool to sync the airbag module with the new BCM and clear the light.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure correct brake light and traction control operation. This can also be performed with a compatible scan tool.
Disclaimer: Procedures can vary. For model-specific instructions, always consult a factory service manual.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that acts as the central command for all non-engine related electronics. This includes power windows, locks, lights, the security system, wipers, and the instrument cluster.
Why is VIN programming so important?
Programming the BCM with your vehicle’s VIN ensures it has the correct software and settings for your specific options (like power seats, keyless entry, etc.). This makes the installation plug-and-play and avoids a mandatory, costly trip to the dealership.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
Do I need to send my old BCM back?
No. This part is sold without a core charge. You can keep your original module, which saves you the time and expense of return shipping.
What tools are needed for installation?
For most applications, you will only need basic hand tools like a socket set or nut driver to remove the trim panels and unbolt the module itself. No special electronic tools are required for the physical installation.
