Restore Your GM’s Electrical System with a Hassle-Free Solution
Are you battling frustrating electrical issues in your 2015 GMC Yukon XL 1500 or another compatible GM vehicle? Problems like unresponsive power windows, flickering dash lights, a faulty security system, or even a no-start condition often point directly to a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause widespread, confusing symptoms. Dealerships often charge a fortune for a new module plus mandatory programming fees. We offer a smarter, more affordable path back to reliability.
This is a comprehensive cloning service for your BCM. Here’s how it works: you purchase this service and ship your original BCM to our facility. Our expert technicians will then perform a full data transfer, cloning all the vehicle-specific information—including VIN, mileage, and key data—to this fully tested replacement module. We then ship the ready-to-install BCM back to you. This process makes the replacement a true plug-and-play solution, completely bypassing the need for expensive dealership programming tools.
Is Your GM Vehicle Showing These BCM Failure Signs?
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Dashboard warning lights illuminate randomly or stay on constantly.
- ✔ Communication error codes, such as U0140, U0155, or other U-series codes, when scanned.
- ✔ Wipers or turn signals behaving erratically or not working at all.
- ✔ Inaccurate fuel gauge or other instrument cluster readings.
A Technician’s Notebook
I recently worked with a customer who owned a 2014 Silverado. He was at his wit’s end. His truck would randomly refuse to start, the radio would cut out, and the power locks had a mind of their own. He had already replaced the battery and checked all the fuses, spending hundreds with no fix. After a quick chat, the symptoms screamed BCM failure. We received his original module, cloned it to one of our replacement units, and shipped it back. He installed it in under 30 minutes in his own driveway. The truck fired right up, and every single electrical gremlin was gone. This cloning service prevents the diagnostic guesswork and gets you right to the solution.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most compatible trucks and SUVs like the Yukon, Tahoe, and Silverado, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black box with multiple large electrical connectors.
- ✔ Remove the Old Module: Carefully unplug all the wiring harness connectors. They have locking tabs that need to be pressed to release. Once unplugged, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all wiring harnesses, making sure each one clicks into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: windows, locks, lights, wipers, etc. Start the vehicle to ensure everything is operating correctly.
Important Post-Installation Information
While our service eliminates the need for initial programming, some vehicle systems may require a relearn or sync procedure after the BCM is replaced. This is a normal part of the vehicle’s security and safety architecture.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function correctly.
We offer a no-hassle process with no core charge, so you can keep your original module. This listing is for a replacement BCM compatible with part numbers 13594692, 13594768, 13593214, 13580690, 13591519, and 13594769.

Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is a process where we transfer the complete software and vehicle-specific data (like VIN and security information) from your original BCM to this replacement unit. This makes the new module plug-and-play, avoiding the need for dealership programming.
So I don’t need to go to the dealer at all?
Correct. Our programming service handles the critical setup. You simply install the module we send you. In some rare cases, a simple relearn procedure may be needed for certain systems like the airbag or brake sensor, which can be done by most local repair shops.
Where is the BCM located on my 2015 Yukon XL 1500?
On the 2015 Yukon XL and similar GM trucks/SUVs, the Body Control Module is typically found under the driver’s side dashboard, attached near the steering column.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data. If your module has severe physical damage (fire, water) or the memory chip is corrupted, data recovery may not be possible. Please contact us to discuss your specific situation before ordering.
Will this fix my airbag light?
If the airbag light is on due to a fault within the BCM itself or a communication issue, this will resolve it. However, if the light comes on after installation, it likely just needs to be synced with the new BCM using the ‘Setup SDM Primary Key’ procedure, as mentioned in the description.
