Is Your GM Vehicle Acting Possessed?
If your 2010 GMC Yukon XL 1500 is suffering from a bewildering array of electrical gremlins, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, managing everything from your power windows and door locks to your interior lighting and security system. When it starts to fail, it can cause intermittent and frustrating problems that seem to have no logical explanation.
From the Diagnostic Bay
We had a 2010 Tahoe come in that was driving the owner crazy. The radio would turn off randomly, the dome lights would flicker, and the power locks worked only when they wanted to. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication error codes pointing to a network issue. We traced it back to the BCM, which was failing internally and disrupting the entire vehicle’s communication bus. Installing a VIN-programmed BCM like this one solved every single issue in one go.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security system or alarm malfunctioning or engaging randomly.
- ✔ The key fob not working consistently to lock or unlock doors.
- ✔ Dashboard warning lights appearing for seemingly unrelated systems.
- ✔ Issues with the radio, climate control, or instrument cluster functionality.
- ✔ A parasitic battery drain that leaves you with a dead battery overnight.
The Plug-and-Play Solution for Your 2010 Yukon XL BCM
Don’t let a faulty module keep your truck off the road. This Body Control Module is a direct, reliable replacement for your original unit. The critical difference with our service is that we program the module to your vehicle’s specific Vehicle Identification Number (VIN) before we ship it to you. This means it arrives loaded with the latest GM software updates, tailored specifically for your vehicle’s options and features. This process eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
Installation is straightforward for the experienced DIYer or any professional technician. Once installed, some vehicles may require a simple relearn procedure, such as for the brake pedal position sensor or airbag system, which can often be done with a high-level diagnostic tool. We take the guesswork out of the repair by handling the most complex part—the programming—for you.
Important Installation Notes:
While this module is delivered ready for installation, certain vehicle systems may require synchronization after the BCM is connected. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: To ensure correct brake light operation and stability control function, a brake pedal position sensor recalibration might be needed.
This module is a dependable solution for a wide range of GM trucks, vans, and SUVs. By replacing your faulty 2010 Yukon XL BCM, you restore the proper function and communication between all your vehicle’s essential electronic components.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We handle the programming for you before shipment. Simply provide us with your vehicle’s VIN during or after checkout, and the module will arrive flashed with the latest GM software specific to your vehicle, ready for installation.
Where is the BCM located on my 2010 Yukon XL?
On the 2010 GMC Yukon XL 1500, the Body Control Module is typically located under the driver’s side of the dashboard, near the steering column. Always disconnect the battery before attempting removal or installation.
Will this fix a parasitic battery drain?
A failing BCM is a very common cause of parasitic battery drain. The module can fail to go into ‘sleep mode’ when the vehicle is off, continuing to draw power and draining the battery. Replacing a faulty BCM often resolves this issue.
What if my original part number isn’t 15921353?
This module is a direct replacement for a long list of interchangeable GM part numbers, including 25892622, 20815898, and many others listed in the description. As long as your original part number is on our cross-reference list, this module will work for your vehicle.
What happens if the airbag light comes on after I install it?
This indicates that the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a compatible high-end diagnostic scan tool to clear the light. This is a standard security procedure on many GM vehicles.
