Are you battling frustrating electrical problems in your vehicle? Intermittent power windows, malfunctioning door locks, a haywire security system, or dashboard lights that have a mind of their own are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your car’s body electronics, and when it fails, it can cause a wide range of confusing and unpredictable issues. This replacement Body Control Module is the definitive solution to restore your vehicle’s electronic functions to factory-perfect operation.
This isn’t just a part in a box. To save you the time, expense, and hassle of a dealership visit, we program this module specifically to your vehicle’s VIN before it ships. Simply provide your VIN after purchase, and we’ll load the latest GM software updates, ensuring it’s ready for installation right out of the box. This critical step ensures compatibility and proper communication with your vehicle’s other electronic systems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and interior lights.
- ✔ The security system or anti-theft light stays on or engages randomly.
- ✔ Key fobs not working or having extremely limited range.
- ✔ Dashboard warning lights illuminating for no reason.
- ✔ Wipers, radio, or climate control systems behaving unpredictably.
- ✔ Communication error codes stored when scanned with a diagnostic tool.
- ✔ Vehicle not starting due to a failure in the immobilizer system, which is controlled by the BCM.
Installation and Required Procedures for the 2011-2013 Caprice Body Control Module
While the physical installation of the BCM is typically straightforward, some post-installation steps are often necessary to ensure all vehicle systems work together correctly. This is not a defect in the part, but a standard security and calibration requirement for modern vehicles.
- Airbag System Sync: If the airbag warning light is illuminated after you install the new BCM, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required. This ensures your brake lights function correctly and that the traction control and stability control systems receive accurate data.
Please Note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic features, such as power windows, locks, lights, wipers, security system, and keyless entry.
Do I need to program this module?
No. We handle the programming for you before we ship the part. You must provide us with your vehicle’s 17-digit VIN at checkout so we can load the correct software for your specific vehicle.
What happens if I forget to provide my VIN?
We cannot program or ship the module without your VIN. Your order will be placed on hold, and we will contact you to retrieve the information, which will delay your shipment.
Is this part difficult to install?
The physical replacement is often simple, involving unplugging the old module and plugging in the new one. However, as noted above, post-installation electronic procedures like an airbag sync or brake sensor relearn may be required and should be performed by a qualified technician with the proper tools.
My airbag light came on after installation. Is the BCM faulty?
No, this is a normal security measure. The new BCM needs to be electronically introduced to the airbag system (SDM) using a professional scan tool. This procedure, often called ‘Setup SDM Primary Key in BCM’, will resolve the light.
Is there a core charge for my old part?
No, there is no core charge for this module. You can keep your original part.
