Restore Command of Your Vehicle’s Electronics
Are you dealing with baffling electrical issues in your GM vehicle? Flickering dashboard lights, power windows with a mind of their own, or a security system that randomly prevents your car from starting? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central hub for your car’s body electronics, and when it falters, it can create chaos. This replacement GM Body Control Module is the definitive solution, arriving at your door pre-programmed to your vehicle’s VIN for a straightforward installation.
A Technician’s Notebook: The “Haunted” Equinox
I remember a 2009 Chevy Equinox that came into my shop last winter. The owner was convinced it was possessed. The horn would blare at random intervals, the interior lights would strobe, and the remote key fob worked only sporadically. He had already replaced the battery and checked all the fuses. After connecting my diagnostic scanner, I saw multiple U-codes (communication errors) pointing to a network problem originating from the BCM. The internal logic was failing. We installed a VIN-programmed BCM, and just like that, the ‘ghost’ was gone. It’s a common failure I’ve seen hundreds of times, where the BCM’s internal circuits break down, causing a cascade of unpredictable electrical problems.
Is Your Vehicle Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your GM Body Control Module is the likely culprit:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system light stays on, or the vehicle won’t start (anti-theft active).
- ✔ The radio or climate control display is blank or behaving strangely.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or U0164.
- ✔ A persistent battery drain that can’t be traced to other components.
The Smart Solution: Pre-Programmed for Your Vehicle
The biggest hurdle in replacing a BCM has always been the expensive and time-consuming programming required at a dealership. We eliminate that step entirely. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash the module with the latest GM-certified software specific to your car’s options and configuration. This ensures seamless integration and often corrects underlying software bugs that the original module may have had. It’s a true plug-and-play fix that saves you time and money.
A Straightforward Guide to Your BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most compatible GM vehicles, the BCM is located under the dashboard, often on the driver’s or passenger’s side, or behind the center console. Refer to a service manual for your specific model’s location.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors. You should hear a ‘click’ as they lock into place.
- ✔ Reconnect Power: Re-attach the negative battery terminal.
- ✔ Perform Relearns: Start the vehicle. Some models may require a Brake Pedal Position Relearn or an Airbag System Sync if a warning light appears. See our notes below for details.
Important Post-Installation Information
While our programming handles the heavy lifting, some systems may need to re-synchronize after the new BCM is installed:
- 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 is only necessary if the light appears.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn might be required to ensure brake lights and traction control function correctly.
- No Core Charge: You are not required to return your old BCM. There is no core charge or deposit associated with this purchase.
Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any part of the process.

Frequently Asked Questions
Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s comfort and convenience features. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and climate controls.
Why do you need my VIN to sell me this part?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings your specific vehicle requires. This makes the module plug-and-play and ensures all features work as intended from the factory.
Is this a difficult part for a DIYer to install?
For someone with basic mechanical skills, the installation is very manageable. It typically involves removing a few dash panels to access the module, unplugging the old one, and plugging in the new one. No special programming tools are required on your end.
Do I need to return my old BCM?
No. We do not require you to send back your original module. There is no core charge associated with this purchase, saving you the hassle and cost of return shipping.
What if my airbag light turns on after I install it?
This is uncommon, but if it happens, it means the new BCM needs to be synced with the airbag system’s Supplemental Deployment Module (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any professional shop with a compatible scan tool.
Will this BCM fit if my original part number isn’t 15819552?
Yes, this module is a direct replacement for a long list of interchangeable GM part numbers. As long as your vehicle is on our compatibility list and you provide your VIN, we guarantee it will be programmed to work correctly.
