Is your 2010 Chevy Tahoe experiencing bizarre electrical problems? You’re not alone.
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. When it begins to fail, it can cause a cascade of confusing and frustrating issues. From power windows that won’t budge to a security system that acts possessed, a faulty BCM can make your reliable SUV feel unpredictable. This isn’t just an inconvenience; it can affect the safety and security of your vehicle.
From the Diagnostic Bay
We had a 2010 Yukon XL (which uses the same BCM) come into the shop with the strangest list of complaints. The radio would change stations on its own, the dome lights would flicker randomly, and the driver’s power lock would only work half the time. The owner had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication error codes pointing back to one component: the BCM. Once we installed a VIN-programmed replacement, every single ghost in the machine vanished. It’s a perfect example of how one failing module can create a dozen seemingly unrelated problems.
Symptoms of a Failing 2010 Tahoe BCM
If you’re noticing any of the following, your Body Control Module may be the culprit:
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Dashboard warning lights (like ‘Service StabiliTrak’ or airbag warnings) appearing without a clear cause.
- ✔ HVAC (heating and air conditioning) controls not responding.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ The radio or infotainment system behaving strangely.
The Direct-Fit, Programmed Solution
Don’t let a faulty module keep you off the road or force an expensive trip to the dealership. This is a direct replacement for your original BCM. We take the hassle out of the repair by pre-programming this module to your vehicle’s specific VIN before it ships. This ensures that the unit integrates seamlessly with your Tahoe’s existing systems and options. By using the latest software updates from GM, we can often resolve issues that were present even in the original factory programming.

This isn’t just a replacement part; it’s a complete solution. Your new 2010 Tahoe Body Control Module arrives ready for installation. Simply provide us with your vehicle’s VIN during checkout, and our technicians will handle the complex programming. This saves you hundreds of dollars in dealership programming fees and diagnostic time. There is no core charge, so you can keep your old part.
Important Post-Installation Information
While this module is delivered programmed, some GM vehicles require a security handshake between modules after installation. Depending on your specific model and circumstances, the following may be necessary:
- Airbag System Sync: If your airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor relearn may be required.
Always consult a factory service manual or a qualified technician if you are unsure about these procedures.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, security system, wipers, and HVAC controls. It’s the brain for your vehicle’s body electronics.
Is this BCM difficult to install?
The physical installation is typically straightforward. On a 2010 Tahoe, the BCM is located under the steering column. It involves removing a few dash panels and disconnecting electrical connectors. The main challenge is typically the programming, which we handle for you before shipping.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
What happens if I install a BCM that isn’t programmed?
An unprogrammed BCM will not work correctly. Your vehicle may not start, and numerous electronic features will be inoperative because the module doesn’t know your vehicle’s specific configuration or security information.
Will I need a mechanic to perform additional procedures?
Possibly. As mentioned, some vehicles require an airbag system sync or a brake pedal position relearn after installation. These procedures require a bi-directional scan tool and are best performed by a qualified technician.
My original part number is different. Will this still fit?
Yes. This module, 20815898, is the replacement for a long list of previous part numbers. As long as your vehicle is listed in the compatibility chart and we program it to your VIN, it will function correctly.
