Restore Full Electrical Control to Your GM Vehicle
Are you dealing with baffling electrical issues in your car, truck, or SUV? Flickering lights, malfunctioning power windows, a temperamental security system, or a dashboard that has a mind of its own are all classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can turn your daily drive into a frustrating ordeal. This isn’t just an inconvenience; it can affect vehicle security and safety. Stop chasing electrical gremlins and get a definitive solution with our professionally programmed BCM, a direct replacement for part number 15093910.
A Technician’s Notebook: The Ghost in the Machine
I once had a 2008 Chevy Impala in my bay that was driving the owner crazy. The radio would turn on by itself, the interior lights wouldn’t turn off, and the key fob worked intermittently. The customer had already replaced the battery and checked all the fuses. A scan showed a dozen communication error codes (U-codes) pointing in every direction. From experience, I know that when multiple, unrelated electronic systems fail at once, the BCM is the prime suspect. It acts as a network gateway, and when it fails, it creates chaos. We swapped in a pre-programmed BCM, and instantly, all the phantom issues vanished. This is a common failure I’ve seen hundreds of times, often caused by voltage spikes or simple component aging.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need:
- âś” Erratic or non-functional power windows, door locks, and mirrors.
- âś” Interior or exterior lights that stay on, won’t turn on, or flicker.
- âś” The security system or horn activates randomly.
- âś” Intermittent issues with the radio or instrument cluster gauges.
- âś” Key fob not responding correctly.
- âś” Communication error codes, such as U0140 (Lost Communication With Body Control Module).
- âś” A no-start condition where the starter doesn’t engage.
Why Choose Our Programmed GM BCM 15093910?
We take the guesswork and hassle out of the repair. Unlike a standard replacement part that requires a trip to the dealership for expensive programming, our BCM arrives at your door ready for installation. 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 vehicle’s configuration. This ensures seamless integration and proper function of all your vehicle’s features right out of the box.
A Straightforward Guide to BCM Installation
- âś” Safety First: Disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to power down completely.
- âś” Locate the BCM: The location varies by model (see fitment list below). It’s typically found under the driver’s or passenger’s side of the dashboard, or behind the center console.
- âś” Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the old BCM and remove it from the vehicle.
- âś” Install the New Module: Mount your new, pre-programmed BCM in the same position as the original. Reconnect all electrical connectors, ensuring they click securely into place.
- âś” Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test your electronics—windows, locks, lights, and radio—to confirm functionality.
Important Post-Installation Steps
While our BCM is programmed for your VIN, some vehicle systems may require a ‘handshake’ procedure after installation to sync properly. These typically require a professional bi-directional scan tool:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.
We make it simple: No core charge is required. You can keep your old module.

Frequently Asked Questions
Frequently Asked Questions
What is the process after I purchase?
After you place your order, you will need to send us your vehicle’s 17-digit VIN. We cannot ship the module until we have this information. Our technicians will then program the GM BCM 15093910 specifically for your car before shipping it.
Is this really a plug-and-play part?
Yes, for most vehicles. Because we program it to your VIN, it eliminates the need for dealer programming. However, as noted above, certain security or safety systems (like airbags) may require a simple relearn procedure with a scan tool for full synchronization.
Do I need to send my old BCM back?
No. There is absolutely no core charge for this part. You can keep, discard, or recycle your original module at your convenience.
Will this fix my specific problem?
This module corrects issues directly caused by a failing BCM. If you are experiencing multiple, unrelated electrical problems as listed in our symptoms section, there is a very high probability this will solve them. Proper diagnosis is always recommended.
What if I have an airbag light after installation?
This is a normal security measure. The new BCM needs to be electronically introduced to the airbag’s Supplemental Deployment Module (SDM). A repair shop with a bi-directional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to clear the light.
