Restore Full Functionality to Your GM Truck or SUV
Is your 2012-2014 GM vehicle suffering from bizarre electrical issues? The Body Control Module (BCM) is the central command center for your vehicle’s body electronics, managing everything from power windows and door locks to interior lighting and the security system. When it begins to fail, it can create a cascade of frustrating and seemingly unrelated problems. This direct-fit BCM, part number 22846364, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
Unlike a generic part from a local store, this BCM is not just a component; it’s a complete, ready-to-install solution. We pre-program the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This crucial step ensures that the BCM recognizes all the specific options and features your truck or SUV was built with, eliminating the need for an expensive trip to the dealership for programming. We load the latest software updates from GM, so you’re getting a module that performs flawlessly from the moment you plug it in.
From the Diagnostic Bay
We had a 2013 Silverado 2500 in the shop that was driving the owner crazy. The dome lights would flicker at random, the radio would shut off unexpectedly, and occasionally the power locks wouldn’t respond. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication loss codes pointing to the BCM. Instead of a complex wiring repair, we installed a VIN-programmed BCM. The installation took less than an hour, and instantly, all the phantom electrical gremlins were gone. It’s a textbook example of how a failing BCM can mimic a dozen other problems.
Common Symptoms of a Failing BCM
- ✔ Intermittent or completely non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (e.g., lights staying on, flickering, or not turning on at all).
- ✔ False warning messages appearing on the driver information center (DIC).
- ✔ The security system acting up, causing the alarm to go off randomly or preventing the engine from starting.
- ✔ Wipers, radio, or climate controls operating on their own.
- ✔ Diagnostic trouble codes (DTCs), especially U-codes, indicating a loss of communication between modules.
Why Choose a Pre-Programmed 2012-2013 Yukon BCM?
Choosing a pre-programmed module is the smartest way to handle a BCM replacement. A new, unprogrammed BCM from a dealer is essentially a blank slate; it requires specialized tools and software subscriptions to make it work with your vehicle. Our service handles this complex process for you. By providing your VIN during checkout, you receive a part that is tailored specifically for your truck. This saves you significant time, money, and the headache of coordinating a visit to a service center. It’s the most efficient path to getting your vehicle back on the road and working correctly.
Installation and Required Procedures
The BCM is typically located under the driver’s side of the dashboard, near the steering column. While the physical replacement is straightforward for a DIYer with basic tools, some electronic ‘handshake’ procedures may be necessary after installation. Depending on your specific model and options, you may need a professional scan tool to perform the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is required. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: To ensure proper brake light operation and stability control function, a brake pedal position sensor recalibration might be necessary.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
Why is it essential to provide my VIN?
Your vehicle’s VIN allows us to program the BCM with the exact software and calibrations for your specific features, such as power seat type, lighting packages, and security system. This ensures a seamless, error-free installation.
Is this BCM truly plug-and-play?
Yes, it is programmed to be plug-and-play for most of the vehicle’s core functions. However, as noted, certain systems like the airbag (SRS) or brake sensor may require a simple relearn procedure with a capable scan tool to fully sync with the new module.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original module, which can be helpful for diagnostic comparison if needed.
What tools will I need for the installation?
You’ll need basic hand tools like a socket set and trim removal tools to access the BCM under the dashboard. A professional-grade diagnostic scan tool may be required for post-installation procedures like the airbag system sync.
Will this fix my specific electrical problem?
This module will resolve any issue directly caused by a faulty BCM. If you are experiencing any of the symptoms listed above, a failing BCM is the most likely cause. However, proper vehicle diagnosis is always recommended to rule out wiring or other component issues.
What does the Airbag System Sync procedure involve?
The ‘Setup SDM Primary Key in BCM’ is a simple software command performed with a bidirectional scan tool. It establishes a secure communication link between the new BCM and the existing airbag module, which turns off the warning light.
