Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you battling bizarre electrical issues in your 2015 GMC Yukon or other compatible GM vehicle? Flickering lights, malfunctioning power windows, a radio with a mind of its own, or a security light that prevents your truck from starting are all classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating and hard-to-diagnose problems. Dealerships often charge a fortune for a replacement and the necessary programming, leaving you with a hefty bill and vehicle downtime.
We offer a straightforward and affordable alternative. This is a fully tested, replacement BCM that comes pre-programmed with your vehicle’s exact data. By cloning the information from your original module, we eliminate the need for expensive dealership programming. The process is simple: you send us your original BCM, we transfer all the critical data (including VIN, mileage, and key information) to this replacement unit, and ship it back to you ready for installation. This ensures a seamless integration with your vehicle’s systems.
A Technician’s Notebook: The Case of the Spooky Suburban
A customer brought in a 2015 Suburban 1500 with a list of complaints that sounded like a haunting. The dome lights would randomly turn on, the driver’s side window wouldn’t go down, and occasionally, it just wouldn’t crank. They had already replaced the battery and checked the alternator. After hooking up my pro-level scanner, I saw multiple communication error codes, specifically a 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 this exact cloning service. The customer sent us their module, we cloned it, and sent the replacement back. They installed it in under 30 minutes, and every single ‘ghost’ in their machine was gone. It’s a testament to how a targeted repair can save hundreds over just replacing parts.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior (flickering, staying on, or not working at all).
- ✔ The security or anti-theft system light is on, preventing the engine from starting.
- ✔ Instrument cluster gauges behaving erratically or not working.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication loss, such as U0140, U0155, or B1001.
- ✔ Radio or infotainment system malfunctions.
A Straightforward Guide to Installation
- ✔ 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 Yukon and Sierra, the BCM is located under the steering column, behind the lower dash panel. On other models, it may be in the LH dash, on the firewall, or even in a quarter panel. A quick search for your specific model will confirm its location.
- ✔ Remove the Old Module: Carefully disconnect the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your pre-programmed replacement BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair.
Important Information After Installation
Our cloning service makes this a near plug-and-play repair, but some vehicle systems may require a ‘handshake’ with the new BCM. Please note the following:
- 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 BCM and is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure correct brake light operation and traction control functionality.
- No Core Charge: You are not required to return your old part to us after the service. Keep your original module.

Frequently Asked Questions
How does the programming service work?
After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, our technicians will extract the data and flash it onto the replacement module. We then ship the ready-to-install BCM back to you, typically within 1-2 business days.
Why is cloning my original BCM better than getting a new one from the dealer?
Cloning transfers your vehicle’s unique VIN, mileage, and key security data. This makes the replacement module plug-and-play, avoiding the expensive and time-consuming programming procedures required by a dealership for a brand new BCM.
What if my original BCM is completely dead or missing?
In most cases, we can still retrieve data from modules that are non-functional. However, if the main processor is destroyed or the module is missing, we cannot perform the cloning service. Please contact us to discuss options if you are in this situation.
Do I need any special tools for installation?
No. Basic hand tools for removing dash panels and unbolting the module are all that’s required for the physical installation. No programming tools are needed on your end.
Will this fix my ‘Service Theft Deterrent System’ message?
Yes, a faulty BCM is a very common cause of this warning message and a no-start condition. Because our module is cloned with your original security data, it will restore the proper function of the anti-theft system.
