Restore Your Vehicle’s Functionality and Peace of Mind
Are you battling frustrating electrical issues in your GM truck or car? Flickering lights, malfunctioning power windows, a dead dashboard, or a vehicle that refuses to start can all point to one central culprit: a failing Body Control Module (BCM). As the nerve center for your vehicle’s body electronics, a faulty BCM can create a cascade of unpredictable problems. This isn’t just an inconvenience; it can be a serious safety concern. We offer a reliable, straightforward solution with this professionally programmed Body Control Module, designed to get you back on the road without the exorbitant costs and scheduling headaches of a dealership visit.
This is a comprehensive mail-in programming service. After your purchase, we will provide instructions for you to send us your original BCM. We then transfer all the critical data—including VIN, mileage, and key information—to this replacement unit. The result is a true plug-and-play module that is synchronized to your specific vehicle. When you receive it back, you simply install it, and your vehicle’s essential functions are restored. This process for your 2014 Sierra Denali 1500 BCM ensures seamless integration with your truck’s existing systems.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely cause. I’ve seen these symptoms countless times in my 20+ years of diagnostics, often leading to misdiagnoses of batteries or alternators when the BCM was the root problem.
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Erratic instrument cluster behavior, with gauges dropping out or warning lights flashing randomly.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Communication error codes, such as U0140, U0155, or other “U” codes indicating a loss of communication with other modules.
- ✔ Complete no-start condition where the starter doesn’t even click.
A Technician’s Notebook: The Phantom Drain
A customer brought in his 2014 Silverado 1500, a cousin to the Sierra, with a classic ‘phantom drain’ complaint. He’d replaced the battery twice and the alternator once, but the truck would still be dead after sitting for a day. No codes were stored initially. During testing, I noticed the dome light would faintly flicker long after the doors were shut. A deep dive into the network data showed the BCM was failing to enter ‘sleep mode,’ keeping other modules awake and slowly draining the battery. We performed this exact cloning service on a replacement BCM. The new module went to sleep properly, the phantom drain was gone, and the customer was relieved to finally have a reliable truck again. It’s a textbook example of how a failing 2014 Sierra Denali 1500 BCM can mimic other component failures.
A Straightforward Guide to Installation
Installing your newly programmed BCM is a manageable task for a DIY enthusiast. The module is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most GM trucks and SUVs like the Sierra, Tahoe, and Suburban, the BCM is mounted to a bracket under the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM from its mounting location.
- Install the New Module: Mount the replacement BCM in the same position and reconnect all electrical connectors, ensuring they click securely into place.
- Reconnect Power: Reattach the negative battery terminal. Your vehicle’s core functions should now be restored.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a quick sync-up procedure after installation. This is normal and depends on your vehicle’s specific configuration.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to prevent issues with the traction control system.
- No Core Charge: You are not required to return your original module to us after the service is complete. There is no core charge or deposit.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions about the 2014 Sierra Denali 1500 BCM
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. The price includes our mail-in cloning service. We transfer the data from your original BCM to this replacement unit, so it arrives ready to install without any additional programming.
How does the mail-in programming service work?
After you complete your purchase, we will contact you with detailed instructions on how to safely remove and ship your original BCM to our facility. Once we receive it, we perform the data transfer and ship the ready-to-install replacement BCM back to you, typically within 1-2 business days.
What if my original BCM is completely dead or not communicating?
In many cases, we can still extract the necessary data even from a non-communicating module. Please contact us with your specific situation before ordering if you suspect your module is severely damaged (e.g., by water or fire).
Is this part number 13580690 the same as 13594692?
Yes, this module is a compatible replacement for several part numbers, including 13580690, 13594692, 13594768, and others listed in the fitment section. Our programming ensures it functions correctly in place of any of these original parts.
Will this fix my ‘Service Theft Deterrent System’ message?
Yes, a faulty BCM is a very common cause of this warning message and a subsequent no-start condition. Because we clone your original key and security information, this programmed module will resolve that issue.
