Restore Flawless Performance to Your GM Vehicle
Are you experiencing frustrating and unpredictable electrical issues in your truck or SUV? Flickering lights, malfunctioning power windows, a dead instrument cluster, or a vehicle that refuses to start are common signs of a failing Body Control Module (BCM). For a premium vehicle like a 2015 Sierra Denali, these problems aren’t just an inconvenience—they undermine the reliability and confidence you depend on. This professionally programmed BCM is the definitive, hassle-free solution to restore your vehicle’s complex electrical system to perfect working order.
Common Failure Symptoms & Your Direct Solution
A faulty BCM can create a cascade of baffling electrical problems. If you’re noticing any of the following, it’s a strong indicator that your module needs attention:
- Intermittent or non-functional interior/exterior lights
- Power windows, door locks, or mirrors behaving erratically
- Warning lights appearing on the dash for no reason (e.g., security, airbag)
- Vehicle failing to start or crank despite a good battery and starter
- Communication errors with diagnostic scan tools (DTCs like U0140)
Our service provides a direct solution. We take a quality-tested replacement BCM and professionally clone the essential data from your original, failing unit. This process ensures that the replacement module is a perfect digital twin, ready to communicate flawlessly with your vehicle’s other computers. This is the most reliable way to fix your 2015 Sierra Denali 1500 BCM without expensive and time-consuming dealership intervention.

Expert Insight: The Digital Handshake
In modern GM vehicles, the BCM acts as the central nervous system, constantly communicating with the Engine Control Module (ECM), Transmission Control Module (TCM), and various other sensors. This is a secure ‘digital handshake.’ Installing a blank or used BCM from another vehicle breaks this handshake, often leading to a no-start condition or a cascade of error codes. Our cloning service perfectly preserves this critical communication link, making the installation of your replacement 2015 Sierra Denali 1500 BCM as smooth and effective as possible.
Simple & Secure Process
- Place Your Order: Complete your purchase. We will contact you with clear, simple instructions and a shipping address.
- Ship Your Original BCM: Securely package and send us your original BCM.
- We Clone & Return: Upon receipt, our technicians will perform the data transfer to the replacement unit within 1-2 business days and ship both your original and the newly programmed BCM back to you.
By choosing this service for your 2015 Sierra Denali 1500 BCM, you are choosing the smartest path back to a fully functional, reliable vehicle. End the electrical guesswork and restore the peace of mind you deserve.
Frequently Asked Questions
How does the cloning process work?
Our technicians use specialized equipment to read the critical immobilizer data, VIN, and vehicle-specific configuration files from your original BCM. We then write this data directly onto the replacement module, creating a perfect electronic match for your vehicle.
Do I need to program this BCM after I receive it?
No. The module arrives ready for installation. Because it has been cloned, your vehicle will recognize it as the original unit, eliminating the need for expensive dealership programming. However, as noted in our policies, some models may require a simple ‘relearn’ procedure for systems like the brake pedal position sensor or airbag module, which can be done with a high-level scan tool.
What part numbers does this module replace?
This BCM is a direct replacement for part numbers 13592137, 13506935, 13506936, 13587704, and 13594764, covering a wide range of 2015-2018 GM cars, trucks, and SUVs.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM has failed, the core data on the memory chip is still recoverable. Please contact us before ordering if your module has severe water or fire damage, as data recovery may not be possible in those rare instances.
How long does the entire service take?
Once we receive your original module, the cloning and testing process typically takes 1-2 business days. We then ship it back to you. Total turnaround time will depend on shipping speeds to and from our facility.
