Are you experiencing frustrating electrical problems in your 2012 Chevrolet Captiva Sport? Issues like flickering lights, malfunctioning power windows or locks, or a security system that acts up on its own are often signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of baffling symptoms. This replacement Body Control Module, part number 15872421, is the reliable solution to restore your vehicle’s functionality and peace of mind.
We make the repair process simple. Unlike a trip to the dealership, which involves towing, high labor costs, and programming fees, our service provides a BCM that is pre-programmed to your vehicle’s specific VIN. Simply provide us with your VIN after purchase, and our experts will flash the module with the latest, most stable software from GM. This ensures that the module is ready for installation right out of the box, saving you time and money.
From the Diagnostic Bay
We had a 2012 Captiva Sport come in with a classic case of BCM failure. The customer reported that the interior lights would stay on, the radio would randomly shut off, and the key fob worked intermittently. After confirming power and grounds to the module were good, we diagnosed a faulty BCM. Instead of a lengthy and costly dealer visit, the customer opted for one of our VIN-programmed units. The new module arrived, they swapped it in the center dash, and nearly all the issues were resolved instantly. A quick brake pedal position relearn was all that was needed to get them back on the road, problem-free.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights
- ✔ Power windows, door locks, or mirrors not working correctly
- ✔ Malfunctioning windshield wipers
- ✔ Vehicle’s security system engaging randomly or preventing the car from starting
- ✔ Warning lights appearing on the dashboard for no reason
- ✔ Intermittent no-start or stalling conditions
- ✔ Communication errors with other vehicle modules

Important Post-Installation Information
While this BCM is programmed for your vehicle, some models may require simple relearn procedures after installation to ensure full functionality. These are not programming steps but rather synchronization processes that can often be done with a capable scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system. This is a security measure and requires a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be necessary.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, lighting, security systems, and door locks. It acts as the central hub for your car’s body electronics.
Do I need to have this BCM programmed by a dealer?
No. We handle the programming for you before we ship the part. Just provide us with your vehicle’s VIN during or after checkout, and we will flash the module with the latest GM software specific to your car.
Is this part difficult to install?
For a 2012 Captiva Sport, the BCM is typically located in the center dash. Installation involves disconnecting the battery, removing some trim panels, and swapping the module. While it’s a manageable job for a DIYer with some experience, some post-installation relearn procedures may require a professional scan tool.
What happens if I don’t provide my VIN?
We cannot ship your order without a VIN. The programming is essential for the module to function correctly in your vehicle. We will hold your order and contact you to get the necessary information.
Will this fix my ‘Service StabiliTrak’ or ‘Service Traction Control’ message?
A faulty BCM can certainly cause these warnings. If the BCM is the root cause of the problem, this replacement module, once installed and synced, should resolve those messages.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
