Is Your GM Vehicle Acting Possessed? It’s Probably the BCM.
Are you dealing with a frustrating array of electrical gremlins in your 2015 Chevrolet Suburban, GMC Yukon, Cadillac Escalade, or other compatible GM vehicle? Do your power windows have a mind of their own? Do your interior lights flicker, or does your security system randomly engage? These aren’t signs of a haunted vehicle; they are classic symptoms of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause widespread and unpredictable problems that are difficult to diagnose.
The Dealership Dilemma vs. Our Simple Solution
Replacing a BCM traditionally means a trip to the dealership, where you’ll face high costs for the part, labor, and the complex programming required to sync the new module to your vehicle’s VIN and specific options. Our solution bypasses this expensive and time-consuming process entirely. We provide a replacement BCM that is precisely programmed using the data from your original module. This cloning service ensures that the replacement unit is a perfect digital match for your vehicle, making the installation process as close to plug-and-play as possible.
From the Diagnostic Bay
We had a 2015 Sierra 1500 come into the shop that was driving the owner crazy. The radio would turn off, the dome lights would flicker while driving, and sometimes the truck wouldn’t start, showing a ‘Service Theft Deterrent System’ message. The battery and alternator tested fine. After checking the main power and ground connections, we suspected the BCM. Instead of sending him to the dealer for a new, unprogrammed module, we performed a cloning service just like this one. We transferred the data from his failing BCM to a replacement unit. He installed it himself in under an hour, and every single one of his bizarre electrical issues vanished. It saved him hundreds of dollars and a massive headache.
Common Symptoms of a Failing BCM
- âś” Erratic or non-functional power windows, door locks, and mirrors.
- âś” Interior or exterior lights staying on, flickering, or not working at all.
- âś” Malfunctioning windshield wipers or horn.
- âś” False alarms from the security system or anti-theft light staying on.
- âś” Inaccurate readings on the instrument cluster gauges.
- âś” Communication errors with other vehicle modules, leading to various warning lights.
- âś” Intermittent no-start conditions related to the vehicle immobilizer system.

Your Solution for a Faulty 2015 Suburban BCM
This service is the most effective way to solve issues related to a faulty 2015 Suburban BCM and other compatible GM models. By cloning your original data, we ensure that all your vehicle’s specific settings, key fob information, and security parameters are retained. This avoids the need for expensive dealer-specific tools for key relearning or module setup, saving you significant time and money.
Installation & Post-Installation Notes
The BCM is typically located under the steering column or on the driver’s side A-pillar/firewall. While installation is generally straightforward, please be aware of the following potential post-installation procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a recalibration of the brake pedal position sensor may be required to ensure proper brake light and traction control functionality.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions.
This BCM is a direct replacement for part numbers: 13592137, 13506935, 13506936, 13587704, 13594764. Please verify your part number and check the extensive fitment list to ensure compatibility with your vehicle.
Frequently Asked Questions
What is a BCM cloning service?
Cloning is the process of reading the critical vehicle-specific data (like VIN, key information, and security settings) from your original BCM and writing it onto the replacement module. This makes the new module an exact digital copy, allowing it to work in your vehicle without further programming.
Why do I have to send you my original BCM?
Your original BCM holds the unique data that is essential for your vehicle to operate correctly. We need it to perform the cloning service. Even if your old module is failing, the data can almost always be successfully extracted.
Is this a plug-and-play installation?
This service makes the installation as close to plug-and-play as possible. Because all the primary vehicle data is cloned, you avoid the most complex dealership programming. However, as noted, some vehicles may require minor relearn procedures (like for the airbag or brake pedal sensor) with a scan tool after installation.
What happens if my airbag light comes on after installation?
If the airbag light appears, it means the new BCM needs to be synchronized with the airbag system’s Sensing and Diagnostic Module (SDM). A professional technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable diagnostic tool to resolve this.
Do I need to return my old BCM as a core?
No, there is no core charge for this part. After we complete the cloning service, we will return your original module to you along with the programmed replacement. You can keep your original module.
How long does the entire process take?
Once we receive your original BCM, our programming service is typically completed within 1-2 business days. The total time will depend on shipping times to and from our facility. We ship the modules back to you promptly and provide tracking information.
