Restore Your Truck’s Electrical System with a Plug-and-Play Solution
Are you dealing with baffling electrical issues in your 2010 Chevrolet Tahoe? Power windows with a mind of their own, dashboard lights flickering like a disco, or a security system that won’t cooperate? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features, and when it starts to go, it can make your truck feel unreliable and frustrating to drive. This isn’t a problem you have to live with.
We offer a dependable and straightforward fix: a replacement Body Control Module, part number 15828601, that arrives at your doorstep fully programmed for your specific vehicle. Using our professional Cloning Service, we transfer your vehicle’s essential data to this replacement unit. This means you can bypass the expensive and time-consuming trip to the dealership for programming. This is the smart, efficient way to get your Tahoe back to 100% functionality.
A Technician’s Notebook: The Tahoe with a Ghost
A few months back, a 2010 Tahoe was towed into my bay. The owner was at his wit’s end. The interior lights would stay on, draining the battery overnight, and the power locks worked intermittently. He’d already replaced the battery twice. A scan showed a flurry of communication error codes, specifically a U0140 (Lost Communication With Body Control Module). Instead of just throwing parts at it, we checked the power and ground feeds to the BCM under the steering column—they were solid. This confirmed our suspicion: the BCM itself was failing internally, causing data corruption on the network. We installed a VIN-programmed BCM just like this one, and within an hour, every single electrical gremlin was gone. It’s a common failure, but with the right part, it’s a very satisfying fix.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. In my 20+ years of experience, these are the symptoms I see most often with this specific part.
- ✔ Erratic or non-functional power windows, locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ Unresponsive key fob or remote start functions.
- ✔ Warning lights on the dashboard, such as the airbag or ABS light, without a clear cause.
- ✔ Diagnostic Trouble Codes (DTCs) related to body systems or communication, such as U0140, U0155, or various B-series codes.
A Straightforward Guide to Your BCM Installation
Installing your new BCM is a manageable job for a DIY enthusiast. The key is taking your time and being organized. Here’s a general guide for a 2010 Tahoe (location may vary on other models).
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10-15 minutes to allow all system capacitors to discharge.
- Locate the BCM: On the Tahoe, the Body Control Module is typically located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- 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.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all the electrical connectors, ensuring each one clicks securely into place.
- Reconnect Power: Reattach the negative battery terminal and tighten it securely.
- Test and Verify: Start your vehicle and test all the functions controlled by the BCM: lights, locks, windows, wipers, etc.
- Post-Installation Steps: In some cases, additional procedures may be needed. If your airbag light is on, an ‘Airbag System Sync’ may be required using a pro-level scan tool. A ‘Brake Pedal Position Relearn’ might also be necessary. Please review the post-install requirements below.

Frequently Asked Questions
Frequently Asked Questions
How does the Cloning Service work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this VIN to access the latest GM software and program the replacement BCM specifically for your vehicle’s options and configuration. This ensures it works correctly right out of the box.
Do I need to send my old BCM back?
No, there is no core charge or return required for this part. The cloning service is performed on our end before shipping, and your original module is always returned to you along with the programmed replacement unit.
Is this something I can install myself?
For many DIYers with basic tools and mechanical aptitude, this is a very manageable installation. The most important part is safely disconnecting the battery and carefully swapping the modules. However, if you are not comfortable working under the dashboard, we recommend professional installation.
What if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. It’s a quick process for any qualified shop.
Will this fix my check engine light?
A BCM typically controls body functions, not engine performance. If your check engine light is on, the problem is more likely with the Engine Control Module (ECM) or a powertrain sensor. A BCM failure can sometimes trigger communication-related warning lights, but rarely the main check engine light.
What is the Brake Pedal Position Relearn?
This is a calibration procedure that ensures the BCM knows the exact position of the brake pedal. It’s important for proper brake light operation and the function of systems like traction control. Like the airbag sync, it may be required on some models and is performed with a diagnostic tool.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
