Restore Full Electrical Function to Your Vehicle
Are you experiencing frustrating and unpredictable electrical problems in your Chevrolet Captiva Sport or other compatible GM vehicle? A failing Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your vehicle’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 issues that are difficult to diagnose. This replacement Body Control Module, part number 20864767, is the definitive solution to get your vehicle operating correctly again.
Is Your 2012 Captiva Sport BCM Failing?
A faulty BCM can manifest in numerous ways, often seeming like multiple unrelated problems. If your vehicle is showing any of these signs, a BCM replacement is likely the repair you need.
Common Symptoms of BCM Failure:
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Malfunctioning security system or persistent ‘Service Theft System’ warnings.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Key fob not being recognized, leading to remote entry/start failure.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ A no-start condition where the engine cranks but won’t fire up.
A Simple, Programmed Solution
Don’t let a complex repair intimidate you. We make it easy. When you purchase this module, you provide us with your vehicle’s VIN. Our technicians will then program the BCM with the latest GM software specific to your car’s configuration. This means that when you receive the part, it’s ready for installation without requiring an expensive trip to the dealership for programming. While the physical swap is straightforward for many DIY mechanics, please be aware of potential post-installation procedures.
Post-Installation Requirements
In some cases, additional steps may be needed to sync the new BCM with other vehicle systems:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor relearn might be necessary.
This module is a direct replacement for a wide range of part numbers and fits many GM models. Please verify your original part number and check the fitment list to ensure compatibility.

You will need to locate the BCM in your vehicle. Its location varies by model (e.g., under the dash, behind the glove box). The part number is printed on a sticker on the module’s housing.
