End Frustrating Electrical Problems and Restore Your Vehicle’s Performance
Are you dealing with bizarre and unpredictable electrical issues in your vehicle? Flickering lights, malfunctioning power windows or locks, a security system that acts on its own, or even a car that refuses to start? These are classic signs of a failing Body Control Module (BCM), the central command center for your vehicle’s body electronics. This isn’t just an inconvenience; it’s a breakdown in your car’s nervous system. We offer a direct, reliable solution: a replacement Body Control Module, professionally programmed to your vehicle’s specific VIN before it ships. This eliminates the need for expensive dealership programming, saving you time, money, and headaches.
Common Symptoms & Your Direct Solution
A faulty BCM can cause a cascade of problems that can be difficult to diagnose. If you’re experiencing any of the following, this module is the likely solution:
- Intermittent or total failure of power windows, door locks, or interior lighting.
- Erratic instrument cluster behavior or warning lights that won’t turn off.
- Problems with the anti-theft or keyless entry systems.
- Communication errors with other modules, often resulting in diagnostic trouble codes (DTCs) like U0140, U0155, or other “U-codes”.
- A no-start condition where the engine cranks but won’t fire up due to security system lock-out.
By ordering our pre-programmed 2008-2013 Cadillac CTS Body Control Module, you are getting a component that is ready for installation right out of the box, restoring the precise functionality your vehicle had when it left the factory.

Expert Insight: The BCM is Your Car’s ‘Middle Manager’
Think of the BCM as the middle manager for your car’s comfort and convenience features. It doesn’t control the engine, but it takes inputs from dozens of switches (like your window switch or door lock button) and commands the corresponding motors and lights to act. Over years of heat cycles, vibrations, and electrical stress, the delicate circuits inside can fail, leading to the frustratingly random issues you’re likely experiencing. Replacing it with a generic, un-programmed unit from a parts store is only half the job. Without the correct VIN-specific software, your car won’t recognize it. Our programming service is the crucial final step, completed for you, that turns a complex electronic repair into a much more manageable installation.
Frequently Asked Questions
Do I need to send you my old BCM?
No. There is no core charge for this part. You can keep your original module, which can be helpful for reference or if you ever need to revert to the original hardware for any reason.
Is this BCM truly ‘plug and play’?
For most vehicles, yes. Because we program it to your VIN, it is ready to be installed and function. However, on some models, certain security or safety systems may require a simple ‘relearn’ procedure. For example, if your airbag light comes on, a ‘Setup SDM Primary Key in BCM’ procedure may be needed with a pro-level scan tool. A brake pedal position relearn might also be necessary. This is normal for this type of repair.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will contact you via email for this information, or you can add it as a note to your order during checkout. We cannot ship your part until we have programmed it.
What if my airbag light is on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the vehicle’s airbag system (SDM). A qualified technician with a high-level diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Will this 2008-2013 Cadillac CTS Body Control Module fix my specific problem?
While this BCM is the solution for the vast majority of the symptoms listed, proper vehicle diagnosis is always recommended. This part will fix issues caused by a failed BCM, but it will not fix problems originating from faulty wiring, sensors, or other modules.
What part numbers does this module replace?
This module is a direct replacement for a large number of GM part numbers. Please carefully check the detailed part number list on this page to confirm that your original number is included.
