Restore Full Functionality to Your GM Vehicle
Are you dealing with baffling electrical issues in your 2015 GMC Yukon or another compatible GM vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts up, or warning lights that won’t turn off are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can make your daily drive frustrating and unpredictable. This isn’t just an inconvenience; it can impact vehicle safety and security.
This is a professionally programmed replacement BCM, a direct-fit solution for part number 13587704. We take the hassle out of the repair by cloning the essential data from your original module. This means no expensive trips to the dealership for programming, no special software, and no lengthy vehicle downtime. You get a reliable part that is truly plug-and-play, restoring your vehicle’s electronics to perfect working order.
From the Diagnostic Bay: The Case of the Haunted SUV
A customer brought in their 2015 Tahoe with a list of problems that sounded like something out of a ghost story. The dome lights would fade on and off while driving, the radio would randomly change stations, and the alarm would go off in their garage for no reason. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw multiple ‘Lost Communication with BCM’ codes (U0140). Instead of a ghost, the vehicle had a failing BCM. We performed our cloning service onto a replacement module. Once installed, every single phantom issue vanished. This process saved them hundreds compared to the dealership and got their family SUV back to being reliable and safe.
Is Your Vehicle Showing These Symptoms?
A failing BCM can cause a wide range of problems. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Erratic or non-functional interior/exterior lights (headlights, tail lights, dome lights)
- ✔ Power windows, door locks, or mirrors not working correctly
- ✔ Vehicle security system faults or false alarms
- ✔ Remote keyless entry failing to respond
- ✔ Wipers or horn activating unexpectedly
- ✔ Warning lights on the dash, such as the airbag or service vehicle light
- ✔ Communication Diagnostic Trouble Codes (DTCs) like U0140, U0155, or B1001
A Straightforward Guide to Installation
Our cloning service makes replacing your 2015 Yukon BCM as simple as possible. After you receive the 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 Yukon, Tahoe, and Sierra, the BCM is located under the steering column, behind the lower dash panel. On other models like the Corvette or CTS, it may be in the driver’s side dash or hinge pillar.
- Remove Connectors: Carefully unplug all electrical connectors from the old BCM. They have locking tabs that need to be depressed to be released. Do not force them.
- Swap the Module: Unbolt or unclip the original BCM and remove it. Install the replacement module you received from us in its place.
- Reconnect Everything: Plug all electrical connectors firmly into the new BCM. Reconnect the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all functions—lights, locks, windows, wipers, etc. Note that some post-install procedures may be necessary as detailed below.
Important Post-Installation Notes
While our goal is a plug-and-play experience, some vehicle systems may require recalibration after the BCM is replaced. This is normal and ensures all related components communicate correctly.
- Airbag System Sync: If the 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 new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure proper brake light and traction control operation.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
Frequently Asked Questions
How does the programming service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer the critical vehicle data to the replacement module and ship it back to you, typically within one business day.
Do I need to send my original BCM?
Yes. To ensure a true plug-and-play installation, we must clone the data from your original module. This preserves your vehicle’s VIN, mileage, and specific electronic options, avoiding the need for dealer programming.
Is there a core charge?
No, there is no core charge for this service. After we clone the data, you are welcome to keep your original, non-functional module.
Will this fix my exact problem?
This module corrects issues directly caused by a faulty BCM. While the symptoms listed are common, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause before ordering.
What if my airbag light comes on after installation?
This can happen occasionally. It simply means the new BCM needs to be electronically synced with the airbag control module. A procedure called ‘Setup SDM Primary Key in BCM’ can be performed with a professional scan tool to resolve this.
