Restore Full Functionality to Your GM Vehicle with a Programmed BCM
If you’re dealing with bizarre electrical issues in your 2015 Sierra Denali 3500—like power windows with a mind of their own, intermittent door locks, flickering interior lights, or a security system that prevents the engine from starting—the root cause is often a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it fails, it can create a cascade of frustrating and seemingly unrelated problems. This service provides a reliable, cost-effective solution by delivering a replacement BCM, part number 13594692, that is professionally programmed with your truck’s original data.
Forget about towing your vehicle to the dealership and paying steep fees for diagnostics and programming. Our expert cloning service makes this a simple, plug-and-play repair. You simply send us your original BCM, and we transfer all the critical information—including VIN, mileage, key data, and specific options—to a fully tested replacement unit. We then ship it back to you, ready for installation. This process ensures seamless integration, preserving all the original functions your vehicle came with from the factory.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Silverado 2500 with a complaint that stumped two other shops. The radio would randomly turn off, the driver’s side power window wouldn’t work, and occasionally, the truck wouldn’t start, displaying a ‘Service Theft Deterrent System’ message. There were no engine codes, just a handful of communication (U-series) codes. After checking the basics, my experience pointed straight to the BCM. These modules are notorious for causing these exact ‘ghost in the machine’ type failures. We performed our cloning service, and the customer had his fully functional truck back the next day without losing any of his programmed keys or settings. This is a classic example of how a failing 2015 Sierra 3500 BCM or its equivalent can create widespread chaos.
Is Your Truck Exhibiting These Electrical Gremlins?
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your Body Control Module needs attention:
- ✔ Power windows or locks operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security or anti-theft system activating incorrectly, causing a no-start condition.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inconsistent operation of windshield wipers.
- ✔ Communication error codes stored, such as U0140, U0155, or other U-series codes pointing to a loss of communication with the BCM.
- ✔ Dashboard warning lights illuminating for no apparent reason.
Your Straightforward BCM Exchange Guide
Our process is designed to be as simple as possible for both DIY enthusiasts and professional technicians. Installing your programmed BCM is a direct swap.
- Step 1: Locate and Remove. On most GM trucks like the Sierra and Silverado, the BCM is located under the steering column, on the driver’s side of the dash. Carefully disconnect the wiring harnesses and remove the module.
- Step 2: Ship Us Your Original. After purchase, we will provide you with detailed shipping instructions. Pack your original BCM securely and send it to our facility.
- Step 3: We Program Your Replacement. Upon receipt, our technicians will meticulously clone all data from your old module to the replacement unit, typically within one business day.
- Step 4: Install the New Module. We ship the plug-and-play replacement BCM back to you. Simply install it, reconnect the harnesses, and enjoy restored functionality.
Important Post-Installation Information
While our cloning service makes this a nearly seamless process, some vehicle systems may require a quick sync-up after the new module is installed. Please be aware of the following potential procedures:
- 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 syncs the airbag system with the new BCM. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function correctly.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance. Best of all, there is no core charge for this service; you can keep your original module.

Frequently Asked Questions
Frequently Asked Questions
What is BCM cloning?
Cloning is the process of reading all the essential, vehicle-specific data from your original Body Control Module and writing it onto a replacement module. This includes the VIN, security information for your keys, and settings for your vehicle’s options. This makes the replacement unit truly plug-and-play.
Will I need to take my vehicle to the dealer after installation?
No. Our cloning service eliminates the need for any dealer programming. In some rare cases, a simple relearn procedure may be needed for the airbag or brake pedal sensor, which can be done by most independent shops if required.
How long does the programming service take?
Once we receive your original BCM, our technicians typically complete the cloning and testing process within 24-48 business hours. We then ship the programmed module back to you promptly.
What if my airbag light comes on after I install it?
This is an uncommon but known possibility. It simply means the BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is there a core charge?
No, there is absolutely no core charge. You are not required to send your original module back to us after the repair, though we need it initially for the cloning process.
Why is this better than buying a used BCM from a salvage yard?
A used BCM from another vehicle will not work in your truck without being programmed by a dealer. It contains the wrong VIN and security data, which will prevent your vehicle from starting. Our service solves this by matching the replacement BCM to your exact vehicle.
