Restore Your Vehicle’s Electrical System with a VIN-Programmed BCM
Are you experiencing a host of frustrating electrical issues in your Chevrolet Caprice or other GM vehicle? From flickering lights and malfunctioning power windows to random warning indicators and security system faults, a failing Body Control Module (BCM) can turn your reliable vehicle into an unpredictable source of stress. The BCM acts as the central nervous system for your car’s body electronics, and when it fails, it can cause widespread, seemingly unrelated problems. This replacement Body Control Module, part number 15948439, is the definitive solution to restore full functionality and peace of mind.

Expert Pro Tip
Before condemning your BCM, always perform a thorough check of your vehicle’s battery, alternator, and primary ground connections (battery to chassis, engine to chassis). A weak battery or a corroded ground wire can cause low voltage conditions that often mimic the symptoms of a faulty BCM. A simple check can sometimes save you hundreds of dollars.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft system activates randomly, preventing the car from starting.
- ✔ False warning lights appear on the dashboard, such as for the airbag, ABS, or traction control.
- ✔ The radio, climate control, or instrument cluster behave erratically or don’t work at all.
- ✔ Wipers or turn signals function incorrectly or activate on their own.
- ✔ A diagnostic scan tool cannot communicate with the BCM.
Why Choose Our 2011-2013 Caprice BCM?

Installation and Post-Install Procedures
While this module is designed for straightforward installation, some vehicles may require additional steps after the part is connected. These are known as relearn procedures and can sometimes be necessary to sync the new BCM with other vehicle systems.
- 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: On some models, a brake pedal position sensor recalibration might be required 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.
