Restore Your Vehicle’s Electrical System with a Pre-Programmed BCM
Are you tired of dealing with bizarre electrical issues in your 2010 Chevy Tahoe? Flickering dash lights, power windows with a mind of their own, or a security system that randomly acts up are classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can make your daily drive frustrating and unpredictable. This isn’t just an inconvenience; it can affect vehicle safety and security.
This is a direct-fit replacement Body Control Module, part number 15093910, for your GM vehicle. The best part? We handle the programming for you. Simply provide your vehicle’s VIN during checkout, and our technicians will flash the module with the latest GM software specific to your Tahoe. This means no expensive trips to the dealership for programming—it arrives at your door ready to install. It’s the most straightforward and reliable way to get your truck’s electronics working like new again.
From the Diagnostic Bay: A Common BCM Failure
A customer brought in a 2010 Yukon XL—a close cousin to the Tahoe—with a complaint that was driving him crazy: a dead battery every morning. He’d already replaced the battery and alternator. We ran a parasitic draw test and found a significant drain. After pulling fuses one by one, we isolated the circuit to the BCM. Even with the key off, the module wasn’t letting the vehicle’s network go to ‘sleep.’ It was constantly active, draining the battery overnight. Swapping in a pre-programmed BCM like this one solved the problem instantly. It’s a fix I’ve performed hundreds of times on these GM platforms.
Is Your Tahoe Showing These BCM Failure Signs?
A failing BCM can cause a wide range of symptoms. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- âś” Power windows, door locks, or mirrors working intermittently or not at all.
- âś” Interior dome lights or exterior lamps staying on or not turning on.
- âś” The security system light is on, or the alarm goes off for no reason.
- âś” Unexplained battery drain that kills your battery overnight (parasitic draw).
- âś” Warning messages on the dash like “Service Theft System.”
- âś” Instrument cluster gauges behaving erratically or going dead.
- âś” Stored diagnostic trouble codes (DTCs) such as U0140, U0155, or other communication errors.
A Straightforward Guide to BCM Installation
For the confident DIYer or professional mechanic, installing this module is a manageable job. Since it’s pre-programmed, you skip the most complex step.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: In the 2010 Tahoe and similar GM SUVs, the BCM is typically located under the driver’s side of the dashboard, near the steering column.
- Disconnect and Remove: Carefully unplug the multiple electrical harness connectors. They have locking tabs, so be gentle. Once disconnected, unbolt the old BCM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in place of the old one and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock in.
- Power Up: Reconnect the negative battery terminal.
- Final Checks & Relearns: Start the vehicle and check all body functions (lights, windows, locks). Depending on your vehicle’s configuration, you may need to perform a simple relearn procedure as detailed below.
Important Post-Installation Information
While this module is designed for a simple installation, some GM vehicles require a ‘handshake’ between new modules. Please be aware of the following potential procedures:
- âś” Airbag System Sync: If your airbag warning light is on after installation, a “Setup SDM Primary Key in BCM” procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- âś” Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function correctly.
- âś” No Core Charge: You are not required to return your old module. There is no core charge or deposit associated with this purchase.
Disclaimer: Always consult a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
How does the VIN programming service work?
After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). Our technicians use this VIN to load the exact software and vehicle-specific options from GM’s database onto the module before we ship it to you.
Do I have to send my old part back?
No. This product comes with no core charge. You can keep your old BCM.
Is this installation truly plug-and-play?
For most vehicles, yes. The VIN programming handles the most difficult part. However, as noted above, some GM vehicles may require a simple relearn procedure for the airbag or brake systems, which may require a professional scan tool.
What if my part number isn’t listed but my vehicle is?
The part numbers listed are a comprehensive cross-reference. If your vehicle is listed, this module is the correct replacement. The pre-programming ensures it functions correctly for your specific model and options.
Will this BCM fix my specific electrical problem?
This module will correct any issue directly caused by a failing BCM. The symptoms listed above are the most common indicators. If you’ve already ruled out fuses, relays, and wiring issues, a faulty BCM is the most probable cause.
