Are you battling bizarre electrical issues in your 2015 GMC Yukon? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can turn your reliable SUV into a source of daily frustration. Before you consider an expensive and time-consuming trip to the dealership, we have a straightforward, reliable solution.
This is a replacement BCM for your vehicle, delivered with our professional programming service. We transfer the critical data from your original module to this replacement unit, making it a true plug-and-play part. This process bypasses the need for costly dealer-specific tools and programming, saving you both time and money. It’s the most efficient way to restore your Yukon’s functionality and peace of mind.
Case Study: A Tricky Diagnosis
A few months back, a 2015 Sierra (which uses the same BCM platform as the Yukon) came into my shop with a complaint that stumped two other technicians. The truck would randomly refuse to start, the radio would stay on after the key was out, and the dome lights would flicker. No consistent trouble codes were stored, just a few intermittent U-codes for lost communication. After checking the main power and ground circuits, I focused on the 2015 Yukon BCM. By monitoring data streams, I saw the BCM was failing to properly enter ‘sleep’ mode, causing the battery drain and communication glitches. Swapping in a cloned BCM like this one solved every single issue instantly. These modules are notorious for causing these exact ‘ghost’ problems.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM is the likely culprit. This module is the solution for restoring proper operation.
- ✔ Erratic or non-functional interior/exterior lights
- ✔ Power windows, door locks, or mirrors working intermittently
- ✔ Horn honking unexpectedly or not working at all
- ✔ Vehicle security system faults or false alarms
- ✔ A/C and climate control blower motor issues
- ✔ Instrument cluster warning lights (like the airbag light) staying on
- ✔ Stored diagnostic trouble codes (DTCs) for lost communication, such as U0140, U0155, or U0164
A Straightforward Guide to Installation
Our cloning service makes the physical swap simple. Once you receive the programmed module from us, you can get your vehicle back on the road by following these general steps.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most 2015 GM trucks and SUVs, including the Yukon, the BCM is located under the driver’s side of the dashboard, near the steering column.
- Remove the Old Module: Carefully disconnect the electrical connectors. They have locking tabs that must be depressed. Once unplugged, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat the replacement BCM into the mounting bracket and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect Battery: Re-attach the negative battery terminal.
- Verify Operation: Start the vehicle and test all body functions—lights, windows, locks, radio, etc.—to confirm the repair was successful.
Important Post-Installation Information
While our programming makes this a near plug-and-play solution, some vehicle systems may require a relearn or sync procedure after installation:
- Airbag System Sync: If the 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.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
- Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any post-installation steps.

Frequently Asked Questions
How does this programming service work?
It’s simple. After you place your order, we will provide instructions for shipping your original BCM to us. Once we receive it, our technicians will transfer all the essential vehicle-specific data to the replacement module. We then ship the ready-to-install BCM back to you, eliminating any need for on-vehicle programming.
Will this fix my specific problem?
This module is the solution for issues directly caused by a failing BCM, such as erratic lights, power accessory failures, and certain no-start conditions. If your vehicle has been properly diagnosed with a bad BCM, this part will resolve those symptoms.
What if my original BCM is completely dead or water damaged?
In many cases, even with significant damage, we can still retrieve the necessary data for the cloning process. Please contact us before ordering if your module has severe physical or water damage so we can discuss the likelihood of a successful data transfer.
Is there a core charge?
No. There is no core charge for this item. We use your original module for data transfer only, and you are welcome to keep it afterward.
How long does the service take?
Our goal is to get you back on the road quickly. We typically program and ship the replacement module within 1-2 business days of receiving your original BCM. We will send you tracking information as soon as it ships.
