Restore Full Electronic Function to Your Vehicle
Are you dealing with bizarre electrical gremlins in your Cadillac DTS or other GM vehicle? Intermittent power windows, flickering lights, strange warning messages, or a security system that acts up are all classic signs of a failing Body Control Module (BCM). The BCM is the central computer responsible for managing your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose issues.
This is a direct replacement Body Control Module, part number 25934763, which comes fully programmed to your vehicle’s specific VIN. We load the latest software updates from GM, ensuring optimal performance and compatibility. This eliminates the need for an expensive trip to the dealership for programming, making this a straightforward and cost-effective solution for both DIYers and professional technicians.
From the Diagnostic Bay
We had a 2008 Cadillac DTS come in with the strangest issue: the driver’s side interior lights would flicker randomly while driving, and the radio would occasionally shut off. The owner had already replaced the battery and checked the alternator. After running diagnostics, we found communication faults pointing to the BCM. Instead of spending hours tracing individual wires, we installed a VIN-programmed DTS Body Control Module. The problems vanished instantly. It’s a classic case of the central ‘brain’ failing and causing widespread, confusing symptoms.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ False “Service Theft System” or other security-related warnings on the dash.
- ✔ Erratic behavior from the radio or climate control system.
- ✔ A “No Communication” error when scanning with a diagnostic tool.
- ✔ Unexplained battery drain that leaves you with a dead battery.

Post-Installation Requirements
No Core Charge: You are not required to return your old module, saving you time and hassle.
While this DTS Body Control Module is designed for a simple installation, some vehicles may require one of the following procedures:
- 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 your vehicle’s airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper function of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is the computer that manages your vehicle’s non-engine related functions. This includes power windows, door locks, interior and exterior lighting, the security system, and other comfort and convenience accessories.
Why do you need my VIN?
We program the module with your vehicle’s specific Vehicle Identification Number (VIN) and the latest GM software. This critical step ensures the BCM communicates correctly with your car’s other computers, making the installation process much smoother and avoiding conflicts.
Is this a difficult part to install?
For most models like the DTS, the BCM is located behind the dash and is accessible with basic hand tools. The primary benefit of our service is that the programming is done for you, eliminating the need for expensive dealer-specific tools.
What if my airbag light is on after I install it?
This is not uncommon. It simply means the new BCM needs to be electronically introduced to the airbag system (SDM). A professional scan tool is required for the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Will this part fit other GM vehicles?
Yes, this BCM is compatible with a very wide range of GM cars, trucks, and vans, including the Chevy Impala, GMC Acadia, Chevy Tahoe, and many others. Please check the extensive fitment list and match your original part number to confirm compatibility.
