Restore Your Vehicle’s Functionality and End Electrical Frustration
Are you battling bizarre electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows or door locks, a security system that acts up, or even a no-start condition can often be traced back to a single, vital component: the Body Control Module (BCM). As the central nervous system for your vehicle’s body electronics, a failing BCM can create a cascade of confusing and frustrating problems. This isn’t just an inconvenience; it can affect your vehicle’s safety and reliability.
This replacement GM Body Control Module, part number 15093910, is the definitive solution. We take the guesswork and dealer-level expense out of the repair. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash the module with the latest GM software specific to your car, truck, or van. It arrives at your door ready for installation, saving you from costly programming fees and lengthy waits at the repair shop.
A Technician’s Notebook: The 2009 Tahoe with a Mind of Its Own
I remember a 2009 Chevy Tahoe that came into my bay with a list of symptoms that had the owner at his wit’s end. The radio would turn on and off randomly, the driver’s side power window wouldn’t work, and the battery would be dead every few mornings. The owner had already replaced the battery and alternator. After connecting my scan tool, I noticed several U-codes, specifically U0140, indicating a loss of communication with the BCM. A quick check of the BCM’s power and ground circuits confirmed they were solid. The module itself was the culprit, failing internally and causing these ghost-like issues. Installing a VIN-programmed GM Body Control Module resolved every single symptom, restoring the vehicle’s functions and the owner’s peace of mind.
Is Your GM Vehicle Showing These BCM Failure Signs?
- ✔ Erratic or non-functional power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Dashboard warning lights illuminate for no apparent reason.
- ✔ Intermittent failure of the radio, climate controls, or windshield wipers.
- ✔ Communication error codes, such as U0140, stored in other modules.
- ✔ Unexplained parasitic battery drain that kills your battery overnight.
Your Straightforward BCM Installation Guide
While the exact location varies by model (see fitment list), the replacement process is generally manageable for a confident DIYer. Always have your vehicle’s service manual handy.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow capacitors to discharge.
- Locate the BCM: The BCM is typically found under the driver’s side dashboard, near the steering column, or behind a kick panel. On some vans, it’s in the center dash area.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all electrical connectors, ensuring they click into place.
- Reconnect Power: Re-attach the negative battery terminal.
- Perform Relearn Procedures: Start the vehicle. As noted below, some models may require a post-installation procedure for the airbag system or brake pedal position sensor if related warning lights appear.
Important Post-Installation Information
Because this GM Body Control Module is pre-programmed, most functions should work immediately. However, due to the complexity of modern vehicle systems, some models may require additional steps:
- Airbag System Sync: If the airbag (SRS) warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some vehicles, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and traction control function.
- No Core Charge: You are not required to return your old module. This saves you the time and hassle of a core return.

Frequently Asked Questions
What exactly is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that acts as a central hub for managing and controlling body-related electronic functions. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and more. When it fails, these systems can behave erratically.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot ship your part until we receive the VIN, as the programming is essential for the module to work correctly in your vehicle.
Is this part truly plug-and-play?
For most vehicles, yes. Because we pre-program it to your VIN, it eliminates the need for dealer programming. However, as noted in the description, some vehicles may require a simple sync procedure for the airbag or brake systems if a warning light appears after installation. This requires a professional scan tool.
What if my original part number isn’t 15093910?
That’s okay. This BCM is a superseded part that replaces over 30 different original GM part numbers. Please check the comprehensive list of compatible part numbers in the description to ensure it’s the correct replacement for your old module.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your old module, saving you the cost and hassle of shipping it back.
