Restore Your Vehicle’s Electrical Sanity
Are you chasing electrical gremlins in your GM truck or SUV? One minute the power windows work, the next they don’t. The radio acts possessed, the security light flashes for no reason, or worse, the vehicle refuses to start. As a technician with over two decades of experience, I’ve seen these frustrating, seemingly unrelated issues hundreds of time. The culprit is almost always a failing Body Control Module (BCM). This isn’t just an inconvenience; it’s a critical failure in your vehicle’s central nervous system.
This is your permanent, hassle-free solution. We provide a fully programmed Body Control Module, compatible with part number 13594768 and others. The process is simple: you purchase this service, ship us your original BCM, and we handle the rest. We will meticulously transfer all the essential data—including VIN, mileage, and security information—from your old module to this replacement unit. When you receive it back, it’s a true plug-and-play install. You get to skip the expensive dealership visit, avoid the programming fees, and get your vehicle back to 100% functionality without the headache.
A Technician’s Notebook: The Suburban That Baffled a Shop
A few months back, a 2015 Suburban was towed to my shop. The owner was at his wit’s end. His regular mechanic had replaced the battery and checked all the fuses, but the truck had a mind of its own. The interior lights would flicker, the horn would honk randomly when locking the doors, and sometimes the instrument cluster would go completely dead while driving. A scan tool showed a flood of U-codes (communication errors) between various modules. This is a classic sign that the central hub—the BCM—is failing. It was no longer managing the data traffic correctly, causing chaos across the entire vehicle network. We performed our BCM cloning service, and the replacement module solved every single issue instantly. It’s a powerful reminder that when multiple, unrelated electrical systems act up, the BCM should be your primary suspect.
Is Your Vehicle Exhibiting These BCM Failure Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft system light stays on, preventing the engine from starting.
- ✔ Instrument cluster gauges behaving abnormally or going dark intermittently.
- ✔ False warnings appearing on the driver information center (e.g., “Service StabiliTrak,” “Service Airbag”).
- ✔ Communication error codes (U-codes) stored in the system, such as U0140, U0155, or U0100.
- ✔ The radio or infotainment system turns on and off by itself.
- ✔ Rapid battery drain while the vehicle is parked.
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 Yukon XL, the BCM is located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug all electrical connectors from the original BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- ✔ Install the Replacement: Mount your new, programmed BCM in the same location. Reconnect all electrical connectors securely into their correct ports.
- ✔ Power Up: Reconnect the negative battery terminal. Your vehicle’s critical data is already on the module, so no further programming is required for basic operation.
Important Post-Installation Information
While this module is delivered ready for installation, some GM vehicles require a ‘handshake’ between modules after a BCM is replaced. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to clear any traction control warnings. This also requires a capable scan tool.
- No Core Charge: You are not required to return your old module to us after the service. There is no core charge or deposit.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step of the process.

Frequently Asked Questions
Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is the process of transferring the unique, vehicle-specific data from your original BCM to the replacement one. This includes the VIN, security keys, and other settings, making the new module a perfect electronic match for your vehicle and avoiding the need for dealership programming.
Do I need to take my vehicle to a dealer after installing this?
No. Our cloning service makes this a plug-and-play solution. The module arrives pre-programmed for your specific vehicle. The only exception may be minor relearn procedures like the airbag sync or brake pedal sensor, which can be done by most independent shops if needed.
Where is the BCM located on my 2015 Yukon XL 1500?
The Body Control Module is typically found under the driver’s side dashboard, attached near the steering column or on the firewall. You will likely need to remove the lower knee bolster panel to access it.
How does the mail-in process work?
After you place your order, we will contact you with detailed instructions and a shipping address. You send us your original BCM. Once we receive it, we perform the cloning service and ship the newly programmed replacement module back to you, typically within 1-2 business days.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM has failed, we can still extract the necessary data. Please contact us with the specifics of your situation before ordering if you suspect a complete module failure.
Is there a core charge for this part?
No, there is absolutely no core charge. You can keep your original module after the programming service is complete.
