Restore Full Functionality to Your GM Vehicle
Are you dealing with baffling electrical issues in your 2010 Tahoe or another compatible GM vehicle? A faulty Body Control Module, or BCM, is often the culprit behind some of the most frustrating and difficult-to-diagnose problems. As the central hub for your vehicle’s body electronics, a failing BCM can wreak havoc, causing everything from flickering lights and malfunctioning power windows to a no-start condition. This isn’t just an inconvenience; it can be a serious safety concern. We offer a reliable, direct-fit solution: a Body Control Module programmed with the latest GM software specifically for your vehicle’s VIN.
Are You Experiencing These Common BCM Failure Symptoms?
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Gauges on the instrument cluster behaving erratically or not working at all.
- ✔ Headlights, taillights, or turn signals operating incorrectly.
- ✔ False warning messages on the driver information center, such as ‘Service StabiliTrak’ or ‘Service Traction Control’.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, often U-codes (e.g., U0140, U0155).
- ✔ The radio or climate control system turns on and off by itself.
A Technician’s Notebook
I remember a 2010 Chevy Tahoe that came into the shop with a laundry list of complaints the owner called “electrical gremlins.” The radio would randomly shut off, the driver’s side window wouldn’t roll down, and the security light would flash intermittently, sometimes causing a no-start. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw multiple communication loss codes with various modules. This pointed directly to a network issue, and at the center of that network is the BCM. After confirming power and ground at the module, we identified the internal failure. Swapping in a VIN-programmed 2010 Tahoe Body Control Module like this one resolved all issues in one go, saving the customer hundreds compared to a dealership visit.
The Advantage of a VIN-Programmed Module
Replacing a BCM isn’t just a simple swap. The module must be programmed to communicate with your vehicle’s specific systems and features. Traditionally, this requires towing your vehicle to a dealership and paying hefty programming fees. We eliminate that entire process. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash this module with the correct, updated GM software before it even ships. This ensures it’s ready for installation right out of the box, saving you time, money, and hassle.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On most 2010 Tahoe models, the BCM is 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 and securely reconnect all the electrical harnesses. Ensure they click into place.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Perform Relearns (If Needed): Start the vehicle. In some cases, you may need a professional scan tool to perform a ‘Brake Pedal Position Relearn’ or an ‘Airbag System Sync’ if related warning lights appear. This is detailed in the post-installation notes below.
Important Post-Installation Procedures
While this module is programmed for your VIN, certain vehicle systems may require a final handshake procedure after installation. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a compatible high-level scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and stability control function, a brake pedal position sensor recalibration might be necessary. This also requires a professional diagnostic tool.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a qualified automotive technician if you are unsure about any part of the installation process.

Frequently Asked Questions
Frequently Asked Questions
Do I need to send my old BCM back?
No, there is absolutely no core charge for this part. You can keep your original module.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the module until we receive this information.
Is this a difficult part to install myself?
For someone with moderate DIY mechanical skill, the physical replacement is straightforward. The main challenge can be accessing the module under the dash. The key is to be aware that post-installation relearn procedures may be required with a professional scan tool.
What if I still have problems after installation?
First, double-check all electrical connections are secure. Second, confirm if any post-install relearn procedures, like for the airbag or brake pedal sensor, are needed for your specific vehicle. If issues persist, the problem may lie in another part of the vehicle’s electrical system.
Will this fix my specific problem?
This module corrects faults originating from the BCM itself. The symptoms listed above are strong indicators of BCM failure. Proper vehicle diagnosis is always recommended to confirm the BCM is the source of the issue before ordering.
What if my part number isn’t 15828601 but is in the list?
The extensive list of part numbers provided in the description are all interchangeable. As long as your original module’s part number is on that list, this unit will function as a correct replacement once programmed to your VIN.
