Restore Your Truck’s Electrical System with a Plug-and-Play Solution
Are you chasing down frustrating electrical gremlins in your GM truck or SUV? Intermittent power windows, flickering dash lights, a security system that acts possessed, or even a no-start condition can often be traced back to one component: a failing Body Control Module (BCM). Think of the BCM as the central nervous system for your vehicle’s body electronics. When it malfunctions, it can cause a cascade of bizarre and unpredictable problems. Dealerships will quote you a hefty price for a new module plus hours of programming labor. We offer a smarter, more affordable solution.
This is a comprehensive cloning service for your vehicle’s BCM. You simply send us your original module, and we transfer all of its critical data—including your vehicle’s VIN, mileage, and specific options—to this fully tested replacement unit. The result? A true plug-and-play module that requires no additional programming upon installation. You get your truck back to perfect working order without the time and expense of a dealership visit.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2015 Silverado 2500 that came into the bay with the strangest set of symptoms the owner had ever seen. The radio would switch stations on its own, the driver’s side window would only work when it wanted to, and occasionally the horn would honk when he used the turn signal. He’d been to two other shops that couldn’t find the issue. After hooking up the scan tool, I saw a slew of communication codes (U-codes) pointing to the BCM. Instead of a costly new module and programming, we performed a cloning service just like this one. In under an hour of shop time for removal and reinstallation, the truck was completely fixed. All the “ghosts” were gone. It’s a perfect example of how the right part, correctly prepared, can save hours of diagnostic headaches.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Erratic or non-working power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft system light is on, preventing the vehicle from starting.
- ✔ Dashboard warning lights flicker or stay on without reason.
- ✔ Communication error codes, such as U0140, U0155, or other U-codes, are present.
- ✔ Wipers, radio, or climate controls operate intermittently or not at all.
- ✔ Key fobs are not being recognized by the vehicle.
A Straightforward Guide to Installation
Our cloning service makes the physical replacement simple. Once you receive your programmed module from us, follow these general steps:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most compatible trucks and SUVs like the Sierra and Silverado, the BCM is located under the driver’s side of the dashboard, near the steering column. On other models like the CTS or XTS, it may be in the LH dash or hinge pillar.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in place and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—windows, locks, lights, wipers, and radio—to confirm the repair.
Important Post-Installation Notes
While our service eliminates the need for programming, some vehicle systems may require a relearn procedure after the BCM is replaced. This is standard for many repairs.
- ✔ Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system. This is only required if the light is on.
- ✔ Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.
- ✔ No Core Charge: You are not required to return your old module to us. This listing has no core charge.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
How does the BCM cloning service work?
After you place your order, we will provide you with shipping instructions. You send us your original BCM. We then extract the unique data and transfer it to the replacement module. We ship the programmed module back to you, ready for plug-and-play installation.
Will I need to program this module at the dealership?
No. The entire point of our service is to avoid dealer programming. Because we clone the data from your original unit, the vehicle recognizes the replacement module as its own, retaining all keys, mileage, and options.
What is a Body Control Module (BCM)?
The BCM is a computer in your car that manages and controls electronic accessories like power windows, interior and exterior lighting, security systems, keyless entry, and wipers.
How long does the entire process take?
We typically program and ship your replacement module the same business day we receive your original. The total time depends on shipping transit times to and from our facility. We will send you a tracking number once it ships.
Is this a guaranteed fix for my vehicle?
This module will fix any issues directly caused by a faulty BCM. It is crucial to properly diagnose the problem first. If you are experiencing the common symptoms listed above, a failing BCM is the most likely cause.
