Is Your GM Vehicle Plagued by Baffling Electrical Problems?
If your 2015 GMC Yukon, Sierra, Tahoe, or another compatible GM model is experiencing a host of strange electrical issues, the root cause is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from your power windows and door locks to the interior lights, security system, and even communication between other critical modules. When it starts to fail, it can create a cascade of frustrating and seemingly unrelated symptoms that can be difficult to diagnose.
From the Diagnostic Bay
We recently had a 2015 Sierra 1500 in the shop with a laundry list of complaints. The owner said the radio would turn on and off by itself, the driver’s side window wouldn’t roll down, and a random “Service StabiliTrak” message would appear on the dash. He’d already replaced the window switch and checked fuses to no avail. After connecting our diagnostic scanner, we saw multiple communication errors pointing back to one source: the BCM. A faulty BCM was corrupting data on the network, causing all these ghost-in-the-machine problems. This pre-programmed module is the exact solution that got his truck back to 100% without a costly trip to the dealer.
The Simple, Plug-and-Play Solution
Forget about expensive dealership programming, towing fees, and vehicle downtime. Our professional programming service provides you with a fully functional, plug-and-play BCM ready for installation. The process is simple: you purchase this listing, send us your original BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. We then ship the ready-to-install module back to you. This cloning process ensures that the replacement BCM is a perfect electronic match for your vehicle, preserving all original functions and avoiding the complex setup procedures required with a new module.
Common Symptoms of a Failing 2015 Yukon BCM
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The vehicle’s security system acting up, preventing the engine from starting (anti-theft light flashing).
- ✔ Horn honking randomly or not working when pressed.
- ✔ Inaccurate or non-functional gauges on the instrument cluster.
- ✔ False warning lights on the dashboard (e.g., ABS, Airbag, StabiliTrak).
- ✔ Problems with the heating and A/C controls.
- ✔ Key fobs not being recognized by the vehicle.
Installation and Post-Install Notes
Installation is straightforward. The BCM is typically located under the steering column on the driver’s side. Simply disconnect the negative battery terminal, unplug the electrical connectors from your old BCM, remove it, and install the replacement unit in its place. Reconnect the connectors and the battery terminal. While our service makes this a plug-and-play part, some GM vehicles may require a couple of simple relearn procedures after installation:
- Airbag System Sync: If the airbag warning light is illuminated 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. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control functionality.
This BCM is a direct fit for part numbers: 13594692, 13594768, 13593214, 13580690, 13591519, and 13594769. Please verify your part number before ordering to ensure compatibility with your vehicle, which includes a wide range of models like the Cadillac Escalade, Chevy Silverado, Suburban, Corvette, and more. Restore your vehicle’s electronic systems to perfect working order with this reliable and hassle-free solution.
Frequently Asked Questions
What does the 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, security system, wipers, and climate controls.
How does this programming service work?
After you place your order, you will ship your original BCM to us. We will then extract the unique data from your module and transfer it to the replacement unit. This ‘cloning’ process makes the replacement BCM fully compatible with your vehicle, requiring no additional programming upon installation.
Is this part truly plug-and-play?
Yes, for over 95% of installations. Because we clone your original data, the vehicle will recognize the module as its own. In some rare cases, as noted in the description, a simple relearn procedure like an airbag sync may be needed, which can be done with a professional scan tool.
Why is cloning my old BCM better than buying a new one from the dealer?
Cloning is significantly more cost-effective and convenient. A new BCM from a dealership is expensive and must be programmed to your vehicle using their proprietary software, which adds labor costs and requires a trip to their service center. Our service bypasses that entire process.
Do I need to send my keys along with my BCM?
No, you do not need to send your keys. All the necessary security and key information is stored within the BCM itself, and we will transfer that data directly to the replacement module.
