Tired of Your Truck’s Electrical Gremlins? Restore Full Functionality Today.
If you’re dealing with baffling electrical issues in your GM vehicle—like power windows with a mind of their own, intermittent starting problems, or dashboard lights that flicker for no reason—you’ve likely pinpointed the culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can cause widespread and frustrating problems. Dealerships often quote astronomical prices for a new module plus mandatory programming fees. We offer a smarter, more affordable solution.
This is a fully tested, reliable replacement BCM that comes programmed specifically for your truck. We utilize a professional cloning service that transfers all the critical data from your original BCM to this replacement unit. This means your vehicle’s unique key information, security settings, and specific options are perfectly preserved. The result is a true plug-and-play module that eliminates the need for expensive dealer programming. Simply send us your original BCM, and we’ll handle the rest, getting you a ready-to-install part shipped back to you promptly.
A Technician’s Notebook: The Case of the Erratic Escalade
A 2015 Escalade rolled into my bay last month with a list of symptoms that sounded like a poltergeist had taken up residence. The radio would change stations on its own, the driver’s side power window wouldn’t work, and the security light would stay on, sometimes preventing it from starting. The owner had already replaced the battery and checked all the fuses. A quick scan revealed a slew of U-codes, all pointing to lost communication with the BCM. Instead of a costly new module and a day tied up at the dealer for programming, we used our cloning service. We transferred the data from his failing BCM to a replacement unit. After a 20-minute install, every single issue was gone. This service saved the customer over $700 and hours of frustration.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays illuminated, causing a no-start condition.
- ✔ Inconsistent operation of the radio, climate controls, or instrument cluster gauges.
- ✔ False warnings on the driver information center (DIC).
- ✔ Diagnostic trouble codes (DTCs) related to lost communication, such as U0140, U0155, or B1001.
- ✔ Horn honking unexpectedly or wipers activating on their own.
A Straightforward Guide to Our Cloning Service & Installation
Our process is designed to be simple and get you back on the road fast. Installing your programmed 2015 Sierra 2500 BCM is a direct replacement.
- Purchase & Ship: After you place your order, we will contact you with instructions to ship your original BCM to our facility. Please ensure your contact information is correct at checkout.
- Expert Programming: Once we receive your module, our technicians will professionally transfer all vehicle-specific data to the replacement BCM.
- Return Shipping: We ship your ready-to-install, programmed BCM back to you, typically within one business day of receipt. We’ll provide tracking information so you know exactly when it’s coming.
- Safety First: Before installation, always disconnect the negative terminal of your vehicle’s battery to prevent electrical shorts.
- Locate and Replace: On most GM trucks like the Sierra and Silverado, the BCM is located under the steering column or on the driver’s side firewall. Carefully disconnect the wiring harnesses and unbolt the old module.
- Install New Module: Mount the new, programmed BCM in place and securely reconnect all wiring harnesses. Reconnect the battery terminal.
- Post-Installation Checks: Start the vehicle and verify that all body functions (lights, locks, windows, etc.) are working correctly. See the notes below regarding potential post-install procedures.
Important Post-Installation Notes
While our cloning makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. These do not always occur but are important to be aware of:
- Airbag System Sync: If the airbag 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.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
Disclaimer: Procedures can vary. Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. The main benefit of our service is that we clone the data from your original module. This means the replacement part arrives at your door fully programmed and ready for installation, saving you hundreds in dealership fees.
What is the turnaround time for the programming service?
We pride ourselves on a fast turnaround. We typically program and ship your replacement BCM back out within one business day of receiving your original module.
Will this fix my specific electrical problem?
This module corrects issues directly caused by a failing BCM, such as problems with power accessories, security system faults, and communication error codes. Proper diagnosis is key, but if your mechanic has condemned the BCM, this is the most effective solution.
What does ‘cloning’ or ‘programming’ mean?
Cloning is the process of reading the essential vehicle-specific information—like the VIN, key codes, and optional feature settings—from your old BCM and writing it precisely onto the replacement unit. This makes the vehicle recognize the new module as its own.
Is it difficult to install the 2015 Sierra 2500 BCM?
For someone with basic mechanical skills, it’s a straightforward job. The BCM is typically located under the dash and is held in by a few bolts and electrical connectors. The most important step is disconnecting the battery first.
