Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM
Are you dealing with baffling electrical issues in your GM car, truck, or SUV? One moment the radio works, the next it doesn’t. Power windows have a mind of their own, and strange warning lights keep appearing on your dash. As a technician with over 20 years of experience, I’ve seen these exact frustrations hundreds of time. The culprit is often a failing Body Control Module (BCM)—the central command center for your vehicle’s body electronics. A faulty BCM can disrupt everything from your interior lights and door locks to the security system, making your vehicle unreliable and frustrating to drive.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professionally prepared Programmed 13587704 BCM, specifically cloned from your vehicle’s original module. This eliminates the need for expensive dealership visits, programming fees, and complex diagnostic tool procedures. You simply send us your old BCM, we transfer all the critical vehicle-specific data to this replacement unit, and ship it back to you ready for installation. It’s the most straightforward and cost-effective way to get your vehicle back to 100% functionality.
Case Study: The Ghost in the 2015 Sierra
A customer brought in his 2015 Sierra 1500 with a list of complaints that sounded like a haunting. The dome lights would flicker randomly, the driver’s side power window would only work intermittently, and occasionally the truck would refuse to start, displaying a “Service Theft Deterrent System” message. His previous mechanic had replaced the battery and checked the alternator, but the problems persisted. After connecting my scan tool, I found a series of U-codes, specifically U0140 (Lost Communication With Body Control Module). This pointed directly to the BCM. Instead of a costly new module and hours of programming, we used a cloning service like this one. Once the cloned BCM was installed, every single electrical gremlin vanished. The truck was fixed in a fraction of the time and cost of a dealership repair.
Is Your Vehicle Showing These Symptoms?
A failing BCM can cause a wide range of issues that may seem unrelated. If you’re experiencing any of the following, your BCM is the likely cause:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, not working, or flickering.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Problems with the radio or infotainment system.
- ✔ Key fob not being recognized or working intermittently.
- ✔ False warning lights on the instrument cluster (e.g., ABS, Airbag, Traction Control).
- ✔ Communication error codes, such as U0140, U0155, or other U-series DTCs.
- ✔ Vehicle security system issues, leading to a no-start condition.
Our Simple Mail-In Cloning Process
We’ve designed our service to be as simple as possible. After your purchase, we will contact you with clear, step-by-step instructions for shipping your original BCM to our facility. Please ensure your contact information is up-to-date in your order. Once we receive your module, our expert technicians will perform a full data transfer to the replacement Programmed 13587704 BCM. We then ship the ready-to-install module back to you, typically within 1-2 business days, and provide you with tracking information. This service ensures all your vehicle’s options and security information are perfectly matched.
A Straightforward Guide to Installation
Installing your newly programmed BCM is a direct replacement. While the exact location varies by model (see fitment list), the process is generally the same. This guide is for informational purposes; always consult a service manual for your specific vehicle.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: The BCM is typically found under the driver’s side dashboard, near the steering column or left-hand kick panel. In some models, it may be on the firewall or in the rear quarter panel.
- Remove Connectors: Carefully unplug all electrical connectors from the old BCM. They have locking tabs that need to be depressed to be released. Do not force them.
- Unbolt the Module: Remove the bolts or nuts securing the BCM to its bracket and remove it from the vehicle.
- Install the New BCM: Mount your new, cloned BCM in the same location and secure it with the original hardware.
- Reconnect Everything: Plug all electrical connectors back into the new module until they click securely in place. Reconnect the negative battery terminal.
- Test Functionality: Start the vehicle and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair.
Important Post-Installation Information
In most cases, this module is fully plug-and-play. However, on some GM platforms, additional steps may be needed to sync related systems. This is normal and does not indicate a problem with the BCM.
- Airbag System Sync: If the airbag (SRS) warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed. This requires a professional-grade scan tool to re-establish communication between the BCM and the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure correct brake light operation and to prevent issues with the traction control or stability control systems.

Frequently Asked Questions
What is this service?
This is a mail-in programming service. You purchase this listing, send us your original BCM, and we transfer its data to a replacement module. We then ship the programmed, ready-to-install BCM back to you.
Why do I need to send my original BCM?
Your original BCM contains vital security information and vehicle-specific settings (like key fob data and optional features). Cloning this data is the only way to guarantee a true plug-and-play installation without needing the dealer.
Is this difficult to install myself?
The physical installation is straightforward for someone with basic mechanical skills. It involves disconnecting the battery, unplugging connectors, and swapping the module. No programming is required on your end.
Do I have to pay a core charge?
No, there is no core charge for this service. You can keep your original, non-functional module.
How long does the process take?
Once we receive your module, the programming and shipping process typically takes 1-2 business days. Shipping times to and from our facility will vary based on your location and chosen shipping speed.
What if the airbag light comes on after installation?
This is a known possibility on some GM vehicles. It simply means the new BCM needs to be electronically introduced to the airbag module using a scan tool procedure called ‘Setup SDM Primary Key in BCM’. A qualified shop can perform this for you.
