Tired of Chasing Electrical Gremlins in Your GM Vehicle?
As a technician with over two decades of diagnostic experience, I’ve seen it all. Flickering lights, power windows with a mind of their own, a security system that randomly immobilizes the vehicle, or a dashboard lit up with warning lights. These frustrating and often difficult-to-diagnose issues frequently point to one central culprit: a failing Body Control Module (BCM). The BCM is the nerve center for your vehicle’s body electronics, and when it starts to fail, it can cause widespread, confusing problems. This isn’t just an annoyance; it can affect safety systems and leave you stranded.
This is the definitive, hassle-free solution. We offer a genuine GM Body Control Module, which directly replaces part number 15837419 and many others. The best part? We handle the most complicated step for you. Simply provide your vehicle’s VIN during checkout, and my team will program the module with the latest GM software specific to your 2010 Tahoe or other compatible vehicle. It arrives at your door ready for installation, saving you a costly trip to the dealership and hundreds of dollars in programming fees.
From the Diagnostic Bay
A customer brought in their 2010 Chevy Tahoe last month with a laundry list of complaints. The radio would turn off, the driver’s side power window wouldn’t work, and the anti-theft light was flashing intermittently, preventing it from starting. They had already replaced the battery and checked fuses. After connecting my scan tool, I saw multiple communication loss codes with various modules. This is a classic sign. Instead of a dozen separate problems, it was one failing BCM causing the chaos. We installed a VIN-programmed 2010 Tahoe Body Control Module, performed the necessary key relearn and system initializations, and the truck was back to perfect working order in under an hour. This part saves immense diagnostic time and prevents you from needlessly replacing other components.
Is Your Vehicle Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ The security or anti-theft system light is on, preventing the engine from starting.
- ✔ Erratic behavior from the radio or instrument cluster gauges.
- ✔ False warning lights appearing on the dashboard (e.g., airbag, ABS).
- ✔ Rapid battery drain when the vehicle is off.
- ✔ Communication errors with a professional scan tool.
A Straightforward Guide to Your BCM Installation
Installing your new 2010 Tahoe Body Control Module is a manageable job for a confident DIYer or a quick task for any professional. For the 2010 Tahoe, it’s typically located under the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
- Locate the BCM: On most GMT900 platform trucks like the Tahoe and Yukon, the BCM is mounted to the left of the steering column, often behind the lower dash panel.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Relearn Procedures: This is a critical step. You will need to perform a security relearn (often called a Passlock or PK3 relearn) to allow the vehicle to start. Additionally, you may need a capable scan tool to perform the ‘Setup SDM Primary Key in BCM’ to clear the airbag light and a ‘Brake Pedal Position Sensor Calibration’.

Frequently Asked Questions
Is this BCM truly plug-and-play?
Almost. Because we program it to your VIN, it eliminates the need for expensive dealer-only programming tools. However, you will need to perform a standard security relearn procedure after installation for the vehicle to recognize the new module and start. This procedure can typically be done without special tools and instructions are widely available online.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and calibrations your vehicle’s specific options require. This ensures all features work correctly, from the type of transmission to the power accessories, providing a seamless replacement.
What if the airbag light is on after installation?
This is a normal security measure. After replacing the BCM, you must perform a ‘Setup SDM Primary Key in BCM’ procedure using a compatible bi-directional scan tool. This re-establishes the secure communication between the BCM and the airbag system’s Sensing and Diagnostic Module (SDM), turning off the warning light.
Do I need to recalibrate the brakes?
Some vehicles, especially those with advanced stability control systems, may require a Brake Pedal Position Sensor calibration after BCM replacement. This ensures the BCM receives accurate input from the brake pedal for proper ABS and traction control function. This also requires a capable scan tool.
Will this fix my specific electrical problem?
The BCM is responsible for a vast number of body-related functions. If you’re experiencing multiple, seemingly unrelated electrical issues like those listed in our symptoms section, a failing BCM is the most likely cause. This part is designed to be a comprehensive fix for those widespread electronic failures.
