Tired of Chasing Electrical Gremlins in Your GM Truck?
As a technician with over two decades in the bay, I’ve seen it all. A customer comes in with a 2015 Silverado 3500, and the story is always the same: the dome lights have a mind of their own, the power windows work intermittently, the radio cuts out, and there’s a frustrating “Service StabiliTrak” message on the dash. These aren’t separate problems; they’re classic symptoms of a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, and when it starts to fail, it creates chaos. This isn’t just an annoyance—it can affect security systems and even leave you stranded.
Instead of facing a massive bill and a long wait at the dealership for a new module that needs complex programming, we offer a straightforward, reliable solution. This is a replacement BCM, part number 13594692, that comes fully programmed by cloning the data from your original unit. This ensures a seamless, plug-and-play installation that retains all your vehicle’s specific settings and key information.
Case Study: A Tricky Diagnosis
I recently had a 2015 Sierra 2500 in the shop with a textbook BCM failure. The owner had already replaced the battery and checked all the fuses, but the intermittent electrical issues persisted. His scan tool was throwing a dozen different communication codes (U-codes), pointing to a network failure. Instead of just selling him a new module, we had him send us his original BCM. We were able to extract all the data, program it onto one of our tested replacement units, and ship it back the next day. He installed it in under 30 minutes, and every single issue was resolved. That’s the power of a proper data clone—it’s a precise fix, not a guess.
Is Your Truck Showing These BCM Failure Signs?
A failing BCM can cause a wide range of confusing symptoms. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Power windows, door locks, or mirrors not working or acting erratically.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ Vehicle’s anti-theft or security system malfunctioning or preventing the engine from starting.
- ✔ Horn honking randomly or not working when pressed.
- ✔ Dashboard warning lights (like ABS, Airbag, or StabiliTrak) illuminating for no reason.
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0140, U0151, or other U-codes.
A Straightforward Guide to BCM Installation
Our cloning service makes the physical swap simple. Once you receive your programmed module from us, follow these general steps. The BCM is typically located under the driver’s side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most GM trucks and SUVs from this era, the BCM is mounted under the steering column or on the driver’s side firewall. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be pressed to release. Once disconnected, unbolt the old BCM and remove it from the vehicle.
- Install the Replacement: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors. Ensure they click into place.
- Power Up and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair.
Important Post-Installation Information
While our programming handles the critical data, some vehicle systems may require a quick sync-up after installation:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple handshake between the modules and is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure flawless operation of the brake lights and traction control system.
Disclaimer: Always consult a factory service manual or a qualified professional for procedures specific to your vehicle’s exact year and model.

Frequently Asked Questions
How does this cloning service work?
It’s simple. After you place your order, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, we transfer all the critical data to a fully tested replacement module. We then ship the ready-to-install BCM back to you, typically within one business day.
Why is this better than buying a used BCM from a junkyard?
A junkyard BCM is programmed for a different vehicle. It will not have your key data, mileage, or specific options. It simply will not work correctly without expensive dealer programming. Our service provides a module that is an exact electronic match to your original, ensuring 100% functionality.
Do I need to do any programming myself?
No. The module you receive from us will be completely plug-and-play. The cloning process handles all the necessary programming. The only potential follow-up steps are the minor system syncs (like for the airbag light) mentioned above, which may be required in some cases.
Is there a core charge for this 2015 Silverado 3500 BCM?
No, there is no core charge. We need your original module to perform the data transfer, but you do not need to worry about returning a core after the fact. The price you see is the final price for the service.
What if my original BCM is completely dead or water damaged?
In many cases, even if the BCM is non-responsive in the vehicle, we can still recover the necessary data directly from the memory chip. Please contact us before ordering if your module has significant physical or water damage so we can confirm the likelihood of a successful data recovery.
