Restore Your Truck’s Brain and End Electrical Frustration

Are you tired of chasing electrical gremlins in your GM truck or van? Intermittent power windows, flickering lights, a security system that acts up, or a vehicle that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable workhorse into a source of constant headaches. It’s the central command for your vehicle’s comfort and convenience features, and when it fails, chaos ensues. This isn’t just an inconvenience; it can affect safety systems like lighting and security.

This is your direct, no-hassle solution. We offer a reliable Body Control Module, part number 15063578, that comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). Simply provide us with your VIN after purchase, and our experts will flash the module with the latest GM software updates before it even leaves our facility. This means no extra trips to the dealership and no need for expensive proprietary scan tools for programming. It’s designed to get you back on the road quickly and with confidence.

From the Diagnostic Bay

Just last month, a 2002 GMC Sierra 2500 was towed into my shop. The owner was at his wit’s end. The radio would turn on by itself, the dome lights wouldn’t turn off, and the power locks were completely unresponsive. He had already replaced the battery and checked all the fuses. A quick scan revealed a slew of communication codes, primarily U-codes pointing to a network failure. After confirming power and ground at the BCM connector, it was clear the module itself was the issue. We installed one of these pre-programmed units, and within an hour, every single electrical gremlin was gone. The owner drove away with a truck that felt new again. This is the definitive fix for those specific, frustrating symptoms.

Is Your GM Vehicle Showing These Symptoms?

A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need.

  • ✔ Power windows, door locks, or mirrors operating erratically or not at all.
  • ✔ Interior or exterior lights flickering, staying on, or not working.
  • ✔ The security system or keyless entry failing to function correctly.
  • ✔ The horn sounding unexpectedly or not working when pressed.
  • ✔ A persistent “Service Vehicle Soon” or security light on the dash.
  • ✔ Common Diagnostic Trouble Codes (DTCs) like U1000, U1016, B1000, or other B-series and U-series communication codes.

A Straightforward Guide to Installation

Replacing the BCM is a manageable job for a DIYer with basic tools. The location can vary, so confirm if yours is under the steering column or behind the center dash trim.

  1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
  2. Locate the BCM: On most Sierra/Silverado models, it’s located under the driver’s side of the dashboard, near the steering column. On vans like the Astro/Safari, it’s often behind the center dash.
  3. Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be pressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
  4. Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
  5. Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, radio, etc.—to confirm proper operation.

Important Post-Installation Steps

After installing your new 2002 Sierra Body Control Module, a couple of crucial recalibration procedures are necessary to ensure full system functionality and safety. These steps are standard practice in any professional shop.

  • Airbag System Reset: The SRS (airbag) warning light will likely be on. You must perform the ‘Setup SDM Primary Key in BCM’ procedure using a compatible bi-directional diagnostic tool. This re-establishes communication between the new BCM and the airbag module.
  • Brake Pedal Position Sensor: Some vehicles require a recalibration of the brake pedal position sensor after BCM replacement. This ensures the brake lights and stability control systems function correctly.

Note: If you are unfamiliar with these procedures, we strongly recommend consulting your vehicle’s service manual or seeking assistance from a qualified technician.

Frequently Asked Questions

Do I need to do any programming myself?

No. This 2002 Sierra Body Control Module arrives pre-programmed to the VIN you provide. It is a plug-and-play installation, though some system recalibrations may be required post-install.

Is this a brand new part?

This is a top-quality, inspected, and tested recycled OEM part, programmed with the latest software for your vehicle, ensuring perfect fit and function.

What happens if I don’t perform the airbag reset?

The airbag warning light will remain illuminated on your dashboard, and more importantly, the supplemental restraint system may not function correctly in the event of a collision.

Will this fix my truck not starting?

It can. The BCM is part of the vehicle’s anti-theft system (Passlock/VATS). If it fails, it can prevent the engine from starting. This module will resolve that issue if the BCM is the root cause.

Where do I send my VIN?

After completing your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the part until we receive this information for programming.

What tools are needed for the job?

Basic hand tools like a socket set and screwdrivers are usually all that’s needed for the physical replacement. However, a professional-grade scan tool is required for the post-installation airbag and brake sensor recalibrations.
