Are you battling a storm of strange electrical issues in your GM truck or SUV? Intermittent wipers, flickering lights, a non-responsive HVAC system, or stubborn power windows are classic signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can create frustrating and difficult-to-diagnose problems. This genuine quality GM Body Control Module, interchangeable with part number 15284816, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
Common Symptoms of a Failing BCM
- ✔ Unpredictable or non-functional HVAC controls and blower motor operation.
- ✔ Power windows, door locks, or mirrors that work intermittently or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) behaving erratically.
- ✔ An illuminated airbag warning light, often accompanied by DTC B1001.
- ✔ Security system malfunctions, causing no-start conditions or random alarm activation.
- ✔ False warnings on the driver information center (DIC).

Installation and Post-Install Procedures
Physically installing the BCM is straightforward. It is typically located under the driver’s side dashboard, near the steering column, and can be swapped out in minutes with basic tools. However, depending on your vehicle’s specific configuration, a couple of post-installation steps may be necessary:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed. This requires a professional-grade diagnostic tool and syncs the new BCM with the airbag system. This is only needed if the light is on.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and traction control function.
