Is Your GM Vehicle Plagued by Electrical Gremlins?
Are you dealing with flickering lights, malfunctioning power windows, or a security system that has a mind of its own? These frustrating and seemingly unrelated electrical issues often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from your interior lights and power locks to your wipers and security system. When it starts to fail, it can create a cascade of confusing problems that are difficult to diagnose.
This listing is for a direct replacement BCM, part number 13506935, that comes with a vital programming service. We eliminate the need for expensive dealership visits and complex programming tools. By cloning the data from your original BCM onto this replacement unit, we provide a true plug-and-play solution, restoring your vehicle’s full functionality quickly and affordably.
From the Diagnostic Bay
We recently had a 2015 GMC Sierra 1500 in the shop that was driving its owner crazy. The radio would randomly change stations, the dome light would stay on, and occasionally, the truck wouldn’t start, displaying a ‘Service Theft Deterrent System’ message. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication errors pointing towards the BCM. Instead of a costly new module and hours of programming at the dealer, we used our cloning service. We transferred the data from his faulty BCM to a replacement unit. Once installed, every single electrical issue was gone. It’s a perfect example of how a failing 2015 XTS Body Control Module, or its equivalent in another GM model, can cause a host of bizarre problems that a simple component swap can solve.
Common Symptoms of a Failing BCM
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ Erratic behavior from the windshield wipers or turn signals.
- ✔ The vehicle’s security system preventing the engine from starting.
- ✔ False warnings on the instrument cluster (e.g., ‘Door Ajar’).
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Issues with key fob recognition and remote start functionality.

Post-Installation Procedures
Our cloning service makes the installation of your replacement 2015 XTS Body Control Module as simple as possible. However, in some GM vehicles, certain systems may require a quick synchronization procedure after the new BCM is connected. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the main computer for your vehicle’s comfort and convenience features. It controls non-engine related functions like power windows, locks, lights, wipers, security systems, and more.
Why is your programming service better than going to the dealer?
Our cloning service transfers the exact data from your old module to the new one. This means the replacement BCM is pre-configured for your vehicle’s specific options and security information, eliminating the need for expensive and time-consuming dealership programming.
Is this installation plug-and-play?
Yes, for the vast majority of functions, it is. You simply disconnect your old BCM and connect the new one. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which can be done with a capable scan tool.
How do I locate the BCM in my vehicle?
The BCM location varies by model. Common locations include under the steering column, behind the driver’s side or passenger’s side kick panel, on the firewall, or in a rear quarter panel. Our fitment list provides general locations for each compatible model.
Do I need to send my keys with my BCM?
No, you do not need to send your keys. Our cloning process transfers all the necessary key and security data directly from your original module, so your existing keys will work perfectly upon installation.
What is the turnaround time for the programming service?
We typically program and ship the replacement module back to you within 24-48 hours of receiving your original BCM at our facility.
