Restore Full Functionality to Your Vehicle’s Electronics
Are you battling bizarre electrical issues in your Cadillac DTS, Chevrolet Impala, or GMC Acadia? Intermittent power windows, flickering interior lights, a malfunctioning security system, or warning messages on your dash are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body-related electronic features, and when it falters, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement Body Control Module is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a straightforward installation.
We had a 2008 Cadillac DTS come into the shop with a complaint of the security light flashing and the car occasionally refusing to start. The owner had already replaced the battery and checked the ignition switch. After connecting our scan tool, we found multiple ‘Loss of Communication’ codes with various modules. All signs pointed to the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our VIN-programmed units. The communication errors vanished, the security system reset, and the car started reliably every time. It’s a common failure, but with a pre-programmed part, it’s a simple fix.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Horn honking unexpectedly or not working.
- ✔ False warning lights on the instrument cluster (e.g., ‘Service Theft System’).
- ✔ Communication issues between various electronic modules.
- ✔ Problems with the heating and A/C blower motor controls.

Don’t let a faulty BCM sideline your vehicle. This module is a direct replacement for a wide range of GM vehicles and part numbers, ensuring broad compatibility. We take the guesswork and hassle out of the repair by programming the module with the latest GM software updates using the VIN you provide. This means no expensive trips to the dealership for programming. Your vehicle will recognize the new module, restoring the functions you’ve been missing.
Post-Installation Information
While this module is designed for a simple installation, some vehicles may require minor post-install procedures. Please be aware of the following:
- Airbag System Sync: If your 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 might be necessary to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We handle the programming for you before shipment. Simply provide your vehicle’s VIN during or after checkout, and the module will arrive ready for installation.
What does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine-related functions, such as power windows, locks, lights, security system, wipers, and climate control features.
Is this compatible with other vehicles besides the Cadillac DTS?
Yes, this BCM fits a wide variety of GM vehicles, including the Chevy Impala, Equinox, Traverse, Express Van, GMC Acadia, Savana Van, Buick Lucerne, and more. Please check the detailed fitment list on this page to confirm compatibility.
What happens if the airbag light comes on after I install it?
This can happen on some vehicles. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade diagnostic tool to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without needing to send it back.
