Restore Full Electronic Functionality to Your GM Vehicle
Is your Cadillac, Chevrolet, GMC, or other GM vehicle suffering from bizarre electrical issues? The Body Control Module (BCM) is the central command center for your car’s body electronics, managing everything from your interior lights and power windows to the security system. When it fails, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement Body Control Module, part number 15299986, is the reliable solution to get your vehicle operating as it should.
Is a Failing BCM Causing Your Problems?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, a replacement module is likely the fix you need:
- ✔ 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 keyless entry.
- ✔ Dashboard warning lights that appear for no reason.
- ✔ Wipers or radio behaving unpredictably.
- ✔ Communication errors with other vehicle modules (DTC U-codes).

Post-Installation Information
In most cases, this module is a simple swap. However, depending on your vehicle’s specific configuration, a couple of minor relearn procedures may be necessary after installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
