Restore Your Vehicle’s Central Command Center
Are you dealing with baffling electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or even a vehicle that refuses to start? These aren’t just random annoyances; they’re classic signs of a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable vehicle into a source of constant frustration. The BCM is the brain behind your car’s body electronics, and when it fails, chaos ensues.
We offer a straightforward, reliable solution. This isn’t just a part in a box; it’s a comprehensive service. You send us your original BCM, and we perform a professional data transfer, or ‘cloning,’ to this fully tested replacement unit. We then ship the ready-to-install module back to you. This process ensures that all your vehicle’s specific settings, key information, and security data are perfectly preserved. The result is a true plug-and-play fix that bypasses the expensive and time-consuming programming required at a dealership.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, locks, or mirrors working intermittently or not at all.
- ✔ The security or anti-theft system preventing the engine from starting.
- ✔ Dashboard warning lights appearing for no reason (e.g., ABS, Airbag, Traction Control).
- ✔ Communication error codes, often in the U-series (like U0100, U0140), indicating a loss of communication with other modules.
- ✔ Rapid battery drain while the vehicle is parked.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Silverado 1500 with a complaint that was driving him crazy: the radio would turn on by itself, and the dome lights would flicker randomly, even when the truck was off, draining the battery overnight. He had already replaced the battery twice. A scan showed a dozen intermittent communication codes. Instead of chasing each code, my experience pointed to the network’s central hub—the BCM. A failing BCM can send corrupt data packets, causing other modules to act erratically. By replacing the BCM with a pre-programmed unit like this one, we solved all the issues in one shot, saving the customer hundreds in diagnostic fees and parts.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate Your BCM: The location varies by model (see fitment list below). Common spots include under the steering column, behind the dash on the driver’s side, or on the firewall.
- ✔ Remove the Original BCM: Carefully unplug the electrical connectors. Most have a locking tab that needs to be depressed or lifted. Once disconnected, unbolt the module from its mounting bracket.
- ✔ Install the New BCM: Mount the replacement module you received from us 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 Final Checks: Start the vehicle and test all body functions—lights, windows, locks, etc. Note the post-installation procedures below, as some models may require an additional step.
Post-Installation System Resets
Our cloning service handles the vast majority of the setup, but due to the complexity of modern vehicle systems, a couple of minor resets may be needed 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 syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure brake lights and traction control function correctly.
Disclaimer: Always consult a factory service manual or a qualified professional if you are unsure about any step. No core charge is required; you can keep your original module.

Frequently Asked Questions
Frequently Asked Questions
What is the process for this cloning service?
After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer all the necessary data to the replacement unit and ship it back to you, typically within 1-2 business days. You’ll receive tracking information once it’s on its way.
Do I need to do any programming myself?
No. The main purpose of our service is to handle all the programming for you. This module will arrive ready to install, saving you a trip to the dealer. Some minor system relearns, like for the airbag or brake pedal sensor, may be needed post-installation as noted above.
Is this Programmed BCM 13587704 a guaranteed fix for my problem?
If your vehicle’s issues match the common symptoms of BCM failure and a professional has diagnosed the BCM as the faulty component, this part is the correct solution. A proper diagnosis is key to avoiding unnecessary repairs.
What happens if I install it and still have problems?
Our modules are fully tested. If issues persist after installation, it’s highly likely there is another underlying problem with the vehicle, such as a wiring short, a faulty ground, or another failing module. We recommend a thorough diagnostic check by a qualified technician.
Is there a core charge for my old BCM?
No, there is no core charge. We only need your original module to perform the data cloning service. You are not required to send it back to us for a refund.
