Is Your Truck Experiencing Bizarre Electrical Problems?
If your 2015 GMC Sierra 3500 is suddenly plagued by a host of frustrating electrical issues—like power windows that won’t cooperate, dashboard lights flickering like a holiday display, or a security system that has a mind of its own—the culprit is often a failing Body Control Module (BCM). The BCM acts as the central nervous system for your truck’s body electronics, coordinating everything from your interior lights and power locks to your instrument cluster and security features. When it starts to fail, it can create a cascade of confusing and unpredictable symptoms that can be difficult to diagnose.
Your Plug-and-Play 2015 Sierra 3500 BCM Solution
Forget about expensive dealership visits, towing fees, and the headache of programming a new module from scratch. We offer a simple, streamlined solution to get your truck back to perfect working order. This listing is for a replacement BCM, part number 13587704, that is professionally programmed using the data from your original module. This cloning service ensures that the replacement BCM is a 100% plug-and-play match for your vehicle, retaining all original keys, settings, and vehicle-specific information. The process is straightforward: you send us your original BCM, we transfer the data to a replacement unit, and we ship the ready-to-install module directly back to you.
From the Diagnostic Bay
We had a 2015 Sierra 2500 come into the shop with the owner at his wit’s end. The radio would randomly shut off, the dome light would stay on, and occasionally the truck wouldn’t recognize the key fob. He’d already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication errors pointing towards the BCM. Instead of a costly new module and hours of programming at the dealer, we performed a cloning service just like this one. The customer was able to install the replacement 2015 Sierra 3500 BCM himself in under an hour, and all the strange electrical gremlins vanished instantly. It’s a reliable fix that saves both time and money.
Common Symptoms of a Failing BCM
- ✔ Power windows, locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) failing to work correctly.
- ✔ The horn or windshield wipers activating randomly.
- ✔ Vehicle security system faults, causing no-start conditions.
- ✔ Inaccurate or non-functional gauges on the instrument cluster.
- ✔ Warning lights such as ABS, Airbag, or Traction Control illuminating on the dash.
- ✔ Key fobs not being recognized by the vehicle.

Post-Installation Information
While our goal is a seamless plug-and-play experience, some GM vehicles may require a simple relearn procedure after installation. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the systems. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light and traction control operation.

Frequently Asked Questions
Why do I need to send you my original BCM?
Your original BCM contains vital security information and vehicle-specific settings (like VIN, mileage, and key data). By cloning this data to the replacement module, we create a true plug-and-play part that avoids the need for expensive dealership programming.
Is this BCM ready to install when I receive it?
Yes, absolutely. Once we program the replacement module with your vehicle’s data, it is ready for immediate installation. In most cases, no further programming is required.
How long does the programming service take?
We typically complete the cloning process and ship your replacement BCM back out within 24-48 hours of receiving your original module.
What if the airbag light comes on after I install it?
This can happen occasionally. It simply means the new BCM needs to be synchronized with the airbag module (SDM). A qualified mechanic with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix my specific electrical problem?
This BCM replacement service is designed to fix issues directly caused by a faulty Body Control Module. While it resolves the vast majority of common electrical symptoms, proper vehicle diagnosis is always recommended to confirm the BCM is the source of your problem.
