Are you experiencing frustrating and unpredictable electrical problems in your Cadillac CTS or other 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 power windows and locks to the interior lights and security system. When it fails, it can create a cascade of baffling issues that are difficult to diagnose.
This is a direct replacement Body Control Module, delivered to you pre-programmed with the latest GM software updates. We flash the module using your vehicle’s VIN, ensuring it’s ready for installation right out of the box. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money. Simply provide your VIN at checkout, and we’ll handle the rest.
From the Diagnostic Bay
We had a 2011 Cadillac CTS in the shop that was driving its owner crazy. The dome lights would flicker randomly, the driver’s side window would sometimes refuse to go down, and the key fob would work intermittently. We checked grounds, wiring, and switches, but everything seemed fine. After connecting a high-level scan tool, we noticed communication dropouts with the BCM. We installed a VIN-programmed module, and instantly, all the electrical gremlins vanished. It’s a perfect example of how this single component can be the root cause of multiple, seemingly unrelated problems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system or anti-theft light staying on or causing no-start conditions.
- ✔ Key fob not being recognized by the vehicle.
- ✔ Dashboard warning lights appearing without a clear cause.
- ✔ Communication errors when using a diagnostic scan tool.

Post-Installation Information
While this module is designed for a simple installation, some vehicles may require additional steps to sync with other onboard systems. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to satisfy the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
