Programmed 2015 Suburban BCM 13587704 | Plug & Play Body Control Module

Restore Your GM’s Electrical System with a Hassle-Free Solution

Is your 2015 Chevrolet Suburban or other GM vehicle acting possessed? Flickering lights, a horn that won’t quit, power windows with a mind of their own, or a dashboard lit up with warning messages are all classic signs of a failing Body Control Module (BCM). I’ve spent over two decades in the garage, and I can tell you that a faulty BCM is one of the most frustrating electrical gremlins a vehicle owner can face. It’s the central nervous system for your vehicle’s comfort and convenience features, and when it goes bad, it can make your truck or SUV nearly impossible to live with.

Forget expensive dealership visits, towing fees, and the headache of programming a new module from scratch. Our service provides a fully tested, reliable replacement BCM that is programmed specifically for your vehicle. We make it simple: after your purchase, you’ll ship your original BCM to us. We then transfer all the critical vehicle data—including VIN, mileage, and key information—to this replacement unit. The result is a true plug-and-play module that gets you back on the road fast, without any additional programming required. This is the most effective way to solve the problem permanently.

Is Your Vehicle Showing These Symptoms?

• ✔ Unpredictable or non-working power windows, locks, or mirrors.
• ✔ Interior or exterior lights flickering, staying on, or not working at all.
• ✔ The security system light is on, or the vehicle won’t start (anti-theft issue).
• ✔ Horn blaring randomly or not working when pressed.
• ✔ Inaccurate gauge readings or warning lights on the instrument cluster.
• ✔ Communication error codes (U-codes) when scanned with a diagnostic tool.
• ✔ Problems with the heating and A/C controls.

Your Straightforward Installation Guide

Installing your programmed 2015 Suburban BCM is a direct process that most DIYers can handle. The location can vary, but it’s typically found under the steering column. Always verify the location for your specific model.

1. Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
2. Locate the BCM: On most Suburbans, Tahoes, and GM trucks, it’s located under the driver’s side dash, near the steering column.
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 BCM and remove it from the vehicle.
4. Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical harnesses. You should hear a ‘click’ as they lock into place.
5. Reconnect Power: Re-attach the negative battery terminal.
6. Test Functions: Start the vehicle and test all body functions—lights, windows, locks, horn, and radio—to confirm the repair is successful.

Post-Installation Note: In some cases, you may see an airbag warning light or need to perform a Brake Pedal Position relearn. These are simple procedures for any shop with a professional scan tool and are often not required. Please see our FAQ for more details.
