Restore Your Truck’s Brain, Not Your Bank Account
Is your 2014 Sierra Denali 1500 acting possessed? Flickering lights, power windows with a mind of their own, or a dashboard lit up with random warnings are classic signs of a failing Body Control Module (BCM). As the central nervous system for your truck’s electronics, when the BCM goes down, it can cause a cascade of frustrating and seemingly unrelated problems. Many owners spend hundreds chasing individual sensor or switch issues, when the real culprit is this central computer.
As a technician with over two decades of experience, I’ve seen firsthand how a faulty BCM can turn a reliable truck into a source of daily headaches. The dealership solution often involves a brand new module, hours of expensive programming, and significant vehicle downtime. We offer a smarter, more efficient solution. This is a fully tested, replacement BCM for part number 13594692 that comes pre-programmed with your vehicle’s exact data. By cloning your original module’s information, we deliver a part that is truly plug-and-play, getting you back on the road without the dealership hassle.
A Technician’s Notebook: The Ghost in the Machine
A customer brought in his 2014 Sierra 1500 with a laundry list of bizarre complaints. The radio would switch stations on its own, the dome light wouldn’t turn off, and the power locks worked intermittently. He’d already replaced the battery and checked all the fuses. A quick scan showed a dozen communication error codes (U-codes) pointing in every direction. This is a tell-tale sign. Instead of playing whack-a-mole with sensors, we went straight for the BCM. After installing a cloned module, every single electrical gremlin vanished. It’s a powerful reminder that sometimes, the most complex problems have a single, central solution.
Is Your Truck Showing These Symptoms?
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ Erroneous warning lights on the instrument cluster (e.g., security, airbag).
- ✔ Communication Loss DTCs, such as U0100, U0140, or U0155.
- ✔ Remote key fob not functioning correctly.
- ✔ The vehicle’s security system preventing it from starting.
Your Straightforward Installation Guide
Installing your pre-programmed 2014 Sierra 1500 BCM is a direct swap. Our cloning service means you skip the complex and expensive dealer programming.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most 2014-2015 GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
- Final Steps: Reinstall any trim panels you removed and reconnect the negative battery terminal. Start the vehicle to confirm that the issues are resolved.
Important Post-Installation Notes: While our cloning makes this a plug-and-play process, some vehicle systems may require a relearn procedure. If your airbag light is on, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” function. Similarly, a Brake Pedal Position Relearn may be required for proper brake light and traction control operation. Always refer to a factory service manual for model-specific details.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will provide instructions for you to ship your original BCM to us. We then extract the vehicle-specific data and transfer it to the replacement module. This ensures all your vehicle’s options and security information are retained, making the installation seamless.
Do I need to take my truck to the dealer after installation?
No, in most cases you will not. Because we clone your original module’s data, this part arrives ready for installation without the need for expensive dealer programming. However, as noted, some specific systems like the airbag or brake pedal sensor may require a simple relearn procedure with a capable scan tool.
Is this a guaranteed fix for my truck’s electrical problems?
This part resolves issues directly caused by a failing BCM. If your vehicle exhibits the common symptoms listed above, a faulty BCM is the most likely cause. Proper diagnosis is key, but for these specific symptoms, this is the most reliable and cost-effective solution.
How long does the entire process take?
Once we receive your original module, our programming and testing process typically takes 1-2 business days. We then ship the replacement BCM back to you. We’ll send you tracking information as soon as it’s on its way.
What does ‘No Core Charge’ mean?
It means you don’t have to pay an extra deposit and you get to keep your original module. We only need your old BCM temporarily for the data cloning process; we will ship it back to you along with your newly programmed replacement.
