Is your GMC Yukon, Tahoe, or other GM vehicle experiencing bizarre electrical problems? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up are common signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose symptoms. This replacement Body Control Module, part number 20864768, is the definitive solution to restore your vehicle’s functionality and peace of mind.
We make the repair process simple. Unlike a trip to the dealership, which involves high costs for the part and separate fees for programming, our BCM arrives at your door ready for installation. Simply provide us with your vehicle’s VIN during checkout, and our experts will program the module with the latest GM software updates specific to your vehicle. This ensures seamless integration and optimal performance right out of the box.
Solving Your Vehicle’s Electrical Gremlins
A faulty BCM can manifest in numerous ways, often leading to confusion and expensive diagnostic time. If you’re experiencing any of the following, a new 2010 Yukon Body Control Module could be the solution you need.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lighting.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Warning lights appearing on the dashboard for no apparent reason (e.g., ABS, Airbag, Traction Control).
- ✔ The radio or climate control system behaving unpredictably.
- ✔ A ‘no-start’ condition where the engine cranks but won’t turn over due to security system interference.
- ✔ Battery drain while the vehicle is parked.
We had a 2010 Yukon XL come in with the owner at his wit’s end. The headlights would flicker, the radio would randomly shut off, and occasionally, the truck wouldn’t start. He’d already replaced the battery and alternator with no success. After a quick scan, we saw multiple communication codes pointing to the BCM. Instead of a costly and time-consuming dealer replacement, we installed one of our VIN-programmed modules. The installation was straightforward, and after a quick brake pedal position relearn, all the electrical gremlins were gone. The customer was thrilled to have his truck back to normal without the dealership hassle.
Installation and Post-Install Information
This module is designed for a direct-fit replacement. After installation, most functions will be immediately restored. However, for safety-critical systems, a couple of simple relearn procedures may be necessary. These are standard industry practice when replacing a BCM.
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This ensures the new BCM and the airbag system are correctly communicating.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be required on some models to ensure proper brake light and traction control operation.
Best of all, there is no core charge for this part. You can keep your original module without the hassle of shipping it back.
Frequently Asked Questions
Is this BCM truly plug-and-play?
Yes, it is pre-programmed to your VIN for a plug-and-play installation of most core functions. However, as with any BCM replacement, certain safety systems like the airbag or brake sensor may require a simple ‘relearn’ procedure with a compatible scan tool to sync with the new module.
How do I provide my vehicle’s VIN?
You can add your 17-digit VIN to the order notes during checkout. If you forget, we will contact you via email to retrieve it before programming and shipping your module.
My original part number is different but is on your list. Will this work?
Absolutely. This BCM, part number 20864768, is a superseded part that replaces all the older part numbers listed in the description. It will function identically and contains the most current software.
Do I need to send my old BCM back?
No. We do not require you to return your original module. There is no core charge associated with this purchase.
What tools are needed for the post-installation procedures?
The relearn procedures, such as the Airbag System Sync, require a professional-grade bidirectional diagnostic scan tool. Many local repair shops can perform these procedures for you quickly.
