Restore Your Vehicle’s Electrical Sanity
Are you chasing down frustrating electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows and locks, a security system that has a mind of its own, or a car that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central command center for your car’s body electronics, a faulty BCM can cause a cascade of seemingly unrelated problems. This isn’t just an inconvenience; it can be a major disruption to your daily life. We offer a reliable, straightforward solution with this GM Body Control Module 15093910, delivered to your door pre-programmed for your specific vehicle.
From the Diagnostic Bay: The Impala with a Ghost
I remember a 2011 Chevy Impala that came into the shop with a laundry list of bizarre symptoms. The owner complained of intermittent no-start conditions, the radio turning off randomly, and the security light flashing on the dash. He’d already replaced the battery and alternator, but the ‘ghost’ remained. After hooking up my scan tool, I found a slew of U-codes (communication errors), specifically U0140 – Lost Communication With Body Control Module. This told me the BCM wasn’t talking to the rest of the car. We installed one of our pre-programmed BCMs, and in under an hour, every single issue was resolved. It’s a classic case I’ve seen hundreds of times; what looks like multiple failures is often just the BCM.
Is Your Vehicle Exhibiting These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need. Check for these common indicators:
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Dashboard gauges behaving erratically or not working at all.
- ✔ The air conditioning or climate control system is unresponsive.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or U0100.
- ✔ The key fob works intermittently or not at all.
The Smart Solution: VIN-Programmed and Ready to Install
The biggest hurdle in replacing a BCM has always been the expensive programming required at a dealership. We eliminate that step entirely. When you order, you simply provide us with your vehicle’s VIN. Our technicians will then flash this GM Body Control Module 15093910 with the latest GM software specific to your car’s configuration. This means the module that arrives at your door is ready for installation right out of the box, saving you hundreds of dollars and a trip to the dealer. Plus, there is no core charge, so you don’t have to worry about the cost or hassle of sending your old part back.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. Wait a few minutes for the system’s capacitors to discharge.
- ✔ Locate the BCM: The location varies by model. On vehicles like the Impala or Acadia, it’s often behind the driver’s side lower dash panel. On Express/Savana vans, it’s typically in the center dash. For Tahoe/Yukon models, check under the steering column. Your service manual can confirm the exact 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 and remove it.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same position as the old one. Securely reconnect all the electrical connectors, ensuring they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test your electronics: power windows, locks, lights, and radio. Start the vehicle and check for any warning lights.
- ✔ Perform Relearn Procedures (If Needed): In some cases, you may need to perform additional sync procedures. If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. A ‘Brake Pedal Position Relearn’ may also be required for proper brake light and traction control operation.

How does the VIN programming service work?
How does the VIN programming service work?
After you place your order, you provide us with your 17-digit Vehicle Identification Number (VIN). Our technicians use this VIN to access the official GM database and load the exact software and calibrations your vehicle requires. This ensures all your specific options (like keyless entry, climate control type, etc.) function correctly.
Do I need to send my old BCM back?
No. This product has no core charge. You can keep your old module, which can be helpful for reference or if you ever need to revert to the original part for any reason.
What do I do if my airbag light is on after installation?
An airbag light after a BCM replacement is not uncommon. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and clear the light.
Is this a difficult part for a DIYer to install?
For most models, the physical replacement is straightforward and requires basic hand tools. The main challenge is usually accessing the module, which may be tucked under the dashboard. Since our module comes pre-programmed, you skip the most difficult part of the job, making it very DIY-friendly.
Will this fix my specific problem?
This GM Body Control Module 15093910 is designed to fix issues directly caused by a failing BCM, such as the symptoms listed above. While it resolves the vast majority of electrical body faults, it’s always best to have a proper diagnosis to confirm the BCM is the root cause before ordering.
