Tired of Unpredictable Electrical Problems in Your GM Vehicle?
Is your truck or SUV acting possessed? Flickering lights, malfunctioning power windows, a dead instrument cluster, or even a frustrating no-start condition can all point to one culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, when the BCM goes bad, it can cause a cascade of baffling issues. Driving a vehicle with a faulty BCM isn’t just annoying; it can be a serious safety concern when features like lighting and security systems become unreliable.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professional cloning service for this BCM, compatible with part numbers like 13594769 and 13594692. Simply send us your original module. Our expert technicians will transfer all the critical, vehicle-specific data—including VIN, mileage, and key programming—to this fully tested replacement unit. We then ship it back to you, ready for installation. This process eliminates the need for an expensive trip to the dealership for programming, saving you significant time and money.
A Technician’s Notebook
I recently had a 2015 Silverado 2500 in the bay that was a real head-scratcher. The customer reported the radio would turn on and off by itself, the dome lights wouldn’t work, and occasionally the truck wouldn’t recognize the key fob. The scan tool showed a dozen intermittent U-codes, all pointing to communication loss. After checking the major power and ground circuits, we isolated the issue to the BCM. Instead of a costly new module and hours of programming, we used a cloned unit. The customer sent their old BCM in, we sent back the programmed replacement, and the install took less than an hour. All the electrical gremlins were gone. It’s a testament to how effective a pre-programmed 2015 Silverado 2500 BCM can be for a complex repair.
Is Your Vehicle Showing These Telltale Signs?
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ The security system or keyless entry is malfunctioning.
- ✔ The instrument panel gauges behave strangely or go dark.
- ✔ The vehicle won’t start, but the battery and starter are good.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140, U0155, or U0164.
- ✔ Horn, wipers, or other accessories activating randomly.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most compatible trucks and SUVs like the Silverado and Sierra, the BCM is located under the steering column, on the driver’s side of the dash. For other models like the Corvette or CTS, it may be in the LH dash area or on the firewall. Always verify the location for your specific vehicle.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that must be depressed to be released. Then, unbolt the module from its mounting bracket.
- ✔ Install the Programmed BCM: Mount the replacement module in the same position and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- ✔ Reconnect the Battery: Reattach the negative battery terminal.
- ✔ Perform System Checks: Start the vehicle and test all body functions—windows, locks, lights, radio, etc. Note that some post-install procedures may be necessary.
Post-Installation Note: In some cases, additional relearn procedures may be required. For instance, if the airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary for proper brake light and traction control function. Always consult a factory service manual for your specific model’s requirements.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Once we receive it, our technicians will copy all the essential programming to the replacement module. We then ship the ready-to-install BCM back to you, typically within 1-2 business days.
Do I need to get this BCM programmed by a dealer?
No. The main benefit of our service is that the module arrives pre-programmed with your vehicle’s data. This allows for a direct installation without the need for expensive dealer-specific software or tools.
Is this a guaranteed fix for my 2015 Silverado 2500 BCM issues?
If your vehicle’s symptoms and diagnostic codes point to a failed BCM, this is a reliable and effective solution. However, we always recommend proper diagnostics to confirm the BCM is the root cause before ordering.
What is a core charge? Do I need to send my old part back?
There is no core charge. However, you must send us your original module first so we can perform the cloning service. You will not need it back afterward.
What if my airbag light comes on after installation?
This can happen occasionally. It requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be done by a professional mechanic with a capable diagnostic scan tool. It’s a simple sync procedure to ensure the new BCM communicates correctly with the airbag system.
