Restore Full Electronic Functionality to Your Cadillac CTS
Is your Cadillac CTS or other GM vehicle plagued by strange and unpredictable electrical problems? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often caused by 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 create a host of frustrating issues. This direct-fit replacement Body Control Module, part number 10382479, is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We had a 2011 Cadillac CTS roll in with a classic case of BCM failure. The customer reported the interior lights would randomly pulse, the radio would shut off, and the “Service Theft System” message was constantly on the dash. They were worried about a massive repair bill for chasing down multiple electrical gremlins. After a quick scan, we confirmed communication loss with the BCM. Instead of a complex and costly diagnostic journey, we installed a VIN-programmed BCM. The car came back to life instantly. All the strange electrical issues vanished. This is a prime example of how replacing the central component can solve a dozen problems at once.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security or anti-theft system engaging randomly, preventing the car from starting.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Warning lights such as the airbag or ABS light staying on.
- ✔ Problems with the keyless entry and remote start systems.
- ✔ Complete loss of power to various accessories.

Post-Installation Procedures
While this module is programmed for your vehicle, some systems may require a simple relearn procedure after installation to sync properly. This is standard for many electronic module replacements.
- 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 may be necessary 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 instructions.
Frequently Asked Questions
What does a Body Control Module do on a Cadillac CTS?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and various other comfort and convenience features.
Do I need to program this BCM?
No. This BCM comes pre-programmed to your vehicle’s specific VIN. Simply provide your VIN during or after checkout, and we handle all the programming before shipping it to you.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming is essential for the BCM to function correctly with your vehicle’s specific options and security system. We will contact you to retrieve the VIN before we can process your order.
My airbag light is on after installation. Is the part defective?
No, this is a normal possibility. The new BCM needs to be electronically introduced to the airbag system (SDM). This requires a “Setup SDM Primary Key in BCM” procedure with a compatible professional scan tool to turn off the light.
Is this part compatible with other vehicles besides the Cadillac CTS?
Yes. This BCM, and its equivalent part numbers, fits a wide range of GM vehicles including the Chevy Impala, GMC Acadia, Chevy Traverse, Buick Enclave, and many more. Please check the detailed fitment list on this page to confirm compatibility.
