Restore Full Functionality to Your GM Vehicle
Are you battling bizarre and frustrating electrical issues in your 2015 Cadillac Escalade, Sierra, or Silverado? From flickering lights and malfunctioning power windows to random warning messages and a dead battery, a failing Body Control Module (BCM) can wreak havoc on your vehicle’s systems. The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, the symptoms can be unpredictable and difficult to diagnose. This listing is for a replacement BCM, part number 13594692 (interchangeable with 13580690, 13594768, 13593214, and others), that is professionally programmed with your vehicle’s original data, providing a seamless, plug-and-play solution.
Why a Simple Swap Won’t Work: The Need for Programming
In modern GM vehicles, the BCM is not a simple plug-in part. It is encoded with your vehicle’s specific Vehicle Identification Number (VIN), security information (for anti-theft systems like Pass-Key), and configurations for all the options your vehicle came with from the factory. Simply installing a used BCM from another vehicle will result in a no-start condition, incorrect feature operation, and persistent error codes. Our professional cloning service completely bypasses these issues. We transfer the critical data from your original, failing module directly onto this replacement unit. The result is a component that your vehicle recognizes as its own, restoring all functions without a costly trip to the dealership for programming.
From the Diagnostic Bay
We recently had a 2015 Sierra Denali in the shop with a classic case of BCM failure. The customer complained that his interior lights would stay on, the radio would randomly shut off, and he’d occasionally get a ‘Service 4WD’ message, even though the 4WD system was mechanically sound. We scanned the vehicle and found a slew of communication error codes pointing to the BCM. Instead of a multi-day, thousand-dollar-plus repair at the dealer, we performed our cloning service. We shipped him the programmed replacement, he installed it in under an hour, and every single electrical gremlin was gone. It’s a powerful fix that saves customers time, money, and immense frustration.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, and mirrors.
- ✔ Headlights, taillights, or interior lights behaving erratically (staying on, not turning on, or flickering).
- ✔ The security system light flashing, or the vehicle refusing to start due to an anti-theft issue.
- ✔ Inaccurate or false warning lights on the instrument cluster (e.g., door ajar, low tire pressure).
- ✔ Malfunctioning windshield wipers or climate control systems.
- ✔ Rapid battery drain while the vehicle is parked.
- ✔ Communication errors when a diagnostic scan tool is connected.
The Simple, Hassle-Free Process
Our goal is to make this repair as straightforward as possible. Here’s how it works:
- Place Your Order: Complete your purchase through our secure checkout.
- We’ll Contact You: Our team will reach out to you using the contact information on your order to provide shipping instructions for your original BCM.
- Ship Us Your Module: Carefully package and send your original BCM to our facility.
- We Program Your Replacement: Upon arrival, our technicians will expertly transfer all necessary data from your old module to the replacement unit. This process typically takes 1-2 business days.
- Receive Your Plug-and-Play BCM: We ship the fully programmed replacement BCM back to you. Once you receive it, simply install it, and you’re ready to go. We will provide tracking information as soon as it ships.
Post-Installation Procedures for Your 2015 Escalade BCM
While our service makes this a plug-and-play installation, some GM vehicles may require a simple relearn procedure after the new module is connected. These are not signs of a faulty part but are standard vehicle-specific sync processes.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and can be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper operation of brake lights and the vehicle’s stability control system.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine-related functions. This includes power windows, locks, lights, wipers, the security system, and the instrument cluster. It acts as a central hub for these electronic features.
Why do I have to send you my original BCM?
Your original BCM contains the unique VIN, security codes, and option configurations for your specific vehicle. By cloning this data to the replacement module, we make it 100% plug-and-play, saving you from expensive and complex dealership programming.
Is this BCM truly plug-and-play after your service?
Yes. Because we transfer all the data from your original unit, the vehicle will recognize the replacement as its own. In most cases, you simply install it and all functions are restored. Some models may require a minor relearn procedure as noted above.
How long does the programming service take once you receive my module?
Our standard turnaround time is 1-2 business days from the time we receive your original BCM. We then ship the programmed replacement back to you promptly.
What happens if I just install a used BCM from a junkyard?
A used BCM from another vehicle will not work correctly. It will have a different VIN and security code, which will likely trigger the anti-theft system and prevent your vehicle from starting. It also won’t be configured for your vehicle’s specific options.
