Are you battling bizarre electrical issues in your Cadillac SRX or other GM vehicle? Flickering lights, malfunctioning power windows, a dead radio, or security system faults are classic signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement Body Control Module is the definitive solution to restore full functionality and peace of mind.
This isn’t just a part in a box. We provide a comprehensive service by pre-programming this module to your vehicle’s specific VIN. This crucial step ensures that the BCM communicates perfectly with your vehicle’s existing systems, eliminating the need for an expensive trip to the dealership for programming. Simply provide your VIN at checkout, and we’ll handle the rest, shipping you a unit that’s ready for installation.
Is Your Body Control Module Failing?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs replacement:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior.
- ✔ Malfunctioning radio, climate controls, or instrument cluster gauges.
- ✔ Key fob not working or vehicle security system acting up.
- ✔ “Service Theft System” or other warning messages on the dash.
- ✔ Communication error codes when scanned with a diagnostic tool.
The Direct-Fit, Programmed Solution
This module is a direct replacement for a wide range of original equipment part numbers, including 20864767. By programming it with the latest GM software updates matched to your VIN, we ensure compatibility and optimal performance for your specific vehicle, whether it’s an SRX, Acadia, Impala, or any of the other models listed in the fitment guide. This process makes the installation as straightforward as possible.
Post-Installation Requirements
While our programming handles the majority of the setup, some vehicles may require minor post-installation procedures. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure using a professional scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be required to ensure correct operation of the brake lights and stability control systems.
Always consult your vehicle’s factory service manual or a qualified automotive technician for specific procedures.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related electronic functions. This includes power windows, door locks, interior and exterior lights, the security system, and the climate controls.
Do I need to program this BCM?
No. This module comes pre-programmed to your vehicle’s VIN. You must provide us with your VIN after purchase so we can load the correct software and vehicle-specific settings before shipping it to you.
Where is the BCM located on a 2007-2009 Cadillac SRX?
On the 2007-2009 Cadillac SRX, the Body Control Module is typically located on the left-hand (driver’s side) of the dash. Location can vary on other compatible models, so it’s always best to consult a service manual for your specific vehicle.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to access the exact factory software and configuration options for your car. This ensures the replacement BCM works perfectly with the features your vehicle was built with, making the installation process much smoother.
What if my airbag light comes on after I install it?
This is not uncommon. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
