Is your 2011-2013 Chevrolet Caprice experiencing bizarre electrical problems? From flickering lights to malfunctioning power accessories, a faulty Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your vehicle’s electronics, and when it fails, it can cause a cascade of frustrating issues. This replacement Body Control Module, part number 15921352, is the definitive solution to restore your vehicle’s proper function and reliability.
We make the repair process simple. Unlike a trip to the dealership, this BCM arrives at your door pre-programmed to your vehicle’s specific VIN. We flash it with the latest GM software updates, ensuring optimal performance and compatibility right out of the box. This eliminates the need for expensive scan tools or programming services after installation. Simply provide your VIN after purchase, and we’ll handle the rest.
From the Diagnostic Bay
We had a 2012 Caprice PPV (Police Pursuit Vehicle) come into the shop with a list of gremlins that seemed unrelated. The dome lights would stay on, the driver’s power window worked intermittently, and the car would occasionally refuse to start, showing a security light. After hours of chasing wires, we isolated the issue to the BCM. It was sending erratic signals across the network. Installing a VIN-programmed BCM like this one solved every single issue in one go. It’s amazing how this single component can restore a vehicle from being a headache to perfectly operational.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Dashboard warning lights (like security or airbag) illuminating for no reason.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
- ✔ Malfunctioning interior or exterior lighting.
- ✔ Climate control or radio systems behaving unpredictably.
- ✔ False alarms from the vehicle’s security system.

Installation and Post-Install Notes
While the physical installation is straightforward, a couple of system relearn procedures may be necessary depending on your vehicle’s configuration.
- Airbag System Sync: If the airbag light is on after installation, a technician will need to perform a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor relearn is required to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
What does the Body Control Module do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and climate controls.
Do I need to get this module programmed?
No. We program the module to your car’s VIN before we ship it to you. This makes the installation process much simpler and avoids a costly trip to the dealership.
Where is the BCM located on a 2011-2013 Caprice?
The Body Control Module on the 2011-2013 Chevrolet Caprice is typically located behind the dashboard, often on the driver’s side.
What happens if I forget to provide my VIN?
We cannot ship your order without a VIN. Programming is essential for the part to function correctly in your vehicle. We will contact you to request the VIN if it is not provided at checkout.
Will this fix my airbag light?
A faulty BCM can cause a false airbag light. However, after installing the new BCM, the system may require a ‘Setup SDM Primary Key’ procedure with a scan tool to sync the modules and turn off the light.
