Is Your 2010 Tahoe Plagued with Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows or locks, a security system that acts on its own, or strange warning lights on your dash, the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a wide array of frustrating and unpredictable issues. Don’t let a faulty module compromise your vehicle’s functionality and safety. This direct-fit replacement BCM is the definitive solution to restore order to your Tahoe’s electrical systems.
From the Diagnostic Bay
We recently had a 2010 Tahoe come into the shop with a classic case of BCM failure. The customer reported that their interior lights would stay on, the radio would randomly shut off, and the power door locks worked intermittently. After confirming power and grounds were good, we diagnosed a faulty BCM. Instead of a lengthy and expensive trip to the dealer for programming, we installed one of our pre-programmed modules. The customer provided their VIN, we programmed the new unit, and the installation was a simple swap. The entire electrical system was back to normal in under an hour. It’s the simplest way to solve a complex problem.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Vehicle’s security system or keyless entry malfunctioning.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Instrument cluster gauges behaving erratically or displaying warning lights.
- ✔ Communication errors with other vehicle modules (U-codes).
- ✔ Battery drain when the vehicle is turned off.

Installation and Post-Install Procedures
Physically replacing the BCM, typically located under the steering column, is a straightforward process for a seasoned DIYer or any professional technician. However, after installing your new 2010 Tahoe Body Control Module, a few additional steps, known as relearn procedures, may be necessary to ensure all vehicle systems are fully synchronized.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This indicates the new BCM needs to be synced with the vehicle’s Sensing and Diagnostic Module (SDM). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be needed to ensure proper operation of the brake lights and the traction control/stability control systems. This also typically requires a compatible diagnostic tool.
While these procedures are not always required, it’s important to be prepared for them. Always consult a factory service manual for your specific vehicle for detailed instructions.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and instrument cluster functions. When it fails, these systems can become unreliable.
Do I need to program this BCM after I receive it?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it to you. This makes the installation process much simpler, as the most complex step is already done.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on the driver’s side of the dashboard, visible through the windshield.
What if my airbag light is on after installation?
If the airbag light comes on, it means the new BCM needs to be synchronized with the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which must be performed with a professional-grade scan tool.
My original part has a different number. Will this still work?
Yes, most likely. This BCM, part number 25934762, replaces a long list of previous GM part numbers. As long as your vehicle is listed in the compatibility chart, this module is the correct, updated replacement for your original part.
