Restore Full Electronic Functionality to Your GM Vehicle
Are you experiencing frustrating electrical issues in your 2008-2013 Cadillac CTS or another compatible GM vehicle? A failing Body Control Module (BCM) is often the culprit behind a host of baffling problems. The BCM acts as the central nervous system for your car’s body electronics, managing everything from your power windows and door locks to the interior lights and security system. When it fails, it can make your vehicle feel unpredictable and unreliable.
This is a direct replacement Body Control Module, part number 15093910, that arrives at your door fully programmed to your vehicle’s specific VIN. We handle the complex flashing process for you, loading the latest GM software updates. This saves you from a costly trip to the dealership for programming, making the repair process faster, simpler, and more affordable.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ Malfunctioning security system or remote keyless entry.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Intermittent operation of the radio or climate controls.
- ✔ A “No Communication” error when scanning with a diagnostic tool.

Post-Installation Procedures
While this module is programmed for your VIN, some vehicles may require minor post-installation steps to sync all systems perfectly. 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 must be performed with a professional scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
Always consult your vehicle’s factory service manual or a qualified technician for specific instructions.

Frequently Asked Questions
What does the Body Control Module do?
The BCM is a computer in your vehicle that controls and monitors many of the non-engine related electronic functions, such as power windows, locks, lights, wipers, security system, and climate controls.
Is this part ready to install out of the box?
Yes, this BCM comes pre-programmed to the VIN you provide. In most cases, it is a plug-and-play installation, though some vehicles may require a simple relearn procedure for certain systems like the airbag or brake pedal sensor as detailed above.
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship the module without it.
Will this fix my specific problem?
This module will correct issues directly caused by a faulty BCM. If you’re experiencing symptoms like erratic lights, non-working power accessories, or security faults, a failing BCM is a very likely cause. Proper vehicle diagnosis is always recommended.
What if my airbag light turns on after I install it?
This can happen on some models. It simply means the new BCM needs to be synced with the airbag system’s Supplemental Deployment Module (SDM). A qualified technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old part back?
No, there is no core charge for this item. You can keep your original module.
