Is Your GM Vehicle Acting Possessed? The BCM is Likely the Culprit.
If your 2015 Chevrolet Suburban, GMC Sierra, Tahoe, or another compatible GM vehicle is plagued by a host of baffling electrical issues, a failing Body Control Module (BCM) is the most common cause. The BCM is the central command center for your vehicle’s body electronics, managing everything from power windows and door locks to interior lighting and the security system. When it starts to fail, it can create a cascade of problems that seem unrelated and are frustrating to diagnose.
Common Symptoms of a Failing BCM
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The vehicle’s security system acting erratically or preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate readings on the instrument cluster gauges.
- ✔ ‘Service Theft Deterrent System’ or other warning messages appearing on the dash.
- ✔ Complete loss of communication with the module when using a diagnostic scan tool.
The Smart Solution: A Plug-and-Play Programmed Module
Replacing a BCM isn’t as simple as swapping the part. A new module from the dealership must be programmed with expensive, specialized tools to recognize your vehicle’s specific VIN and security information. Our professional cloning service completely eliminates this step. You simply send us your original BCM, and we perform a full data transfer to this replacement unit. We extract the VIN, key data, and other vehicle-specific settings and flash them onto the replacement module. When you receive it back, it’s a true plug-and-play solution. No additional programming, no key relearn procedures, and no trip to the dealer is required.

Installation and Post-Install Considerations
Physically installing the BCM is straightforward, typically located under the steering column or on the LH firewall. Once our programmed module is installed, your vehicle should start and run with all primary functions restored. However, in some cases, certain secondary systems may require a simple recalibration procedure.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. This is a simple sync that can be performed with a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be necessary on some models.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
