Tired of Electrical Gremlins in Your GM Vehicle?
As a technician with over two decades of experience, I’ve seen it all. One of the most frustrating issues for vehicle owners is a failing Body Control Module (BCM). Your 2015 Corvette, Sierra, or Cadillac isn’t just a machine; it’s a complex network of electronics, and the BCM is the central command. When it starts to fail, you get bizarre, unpredictable problems: power windows with a mind of their own, dashboard lights flashing like a holiday display, or a security system that randomly prevents you from starting your car. It’s enough to make anyone pull their hair out.
This isn’t just a part; it’s a permanent solution. We offer a professional programming service for this BCM, compatible with part number 13592137 and other interchangeable numbers. The process is simple: you send us your original BCM, we transfer all the critical, vehicle-specific data to this fully tested replacement unit, and we ship it back to you. The result is a true plug-and-play module that restores your vehicle’s functionality without a costly trip to the dealership for programming.
From the Diagnostic Bay: The Case of the Possessed Pickup
A customer brought in his 2015 Sierra 1500, completely fed up. He said, “One day the radio works, the next it doesn’t. The dome light stays on, draining the battery, and sometimes the power locks just quit.” He’d been to two other shops that couldn’t pinpoint the problem. After hooking up my scan tool, I saw multiple communication codes (U-codes) pointing to the BCM. Instead of just selling him a new module that would require expensive programming at the dealer, we performed a cloning service just like this one. He swapped the module himself in his driveway in under 30 minutes. He called back a week later, ecstatic that his truck was finally “cured.” This service saves you that diagnostic headache and gets you a reliable fix, fast.
Is Your Vehicle Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, a failing BCM is the likely culprit:
- ✔️ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔️ Interior or exterior lights staying on, flickering, or not turning on.
- ✔️ The anti-theft or security system light is illuminated, causing a no-start condition.
- ✔️ Inconsistent operation of the radio, climate controls, or instrument cluster gauges.
- ✔️ False warnings on the driver information center (e.g., “Service Airbag System”).
- ✔️ Communication error codes like U0140, U0155, or B1001 stored in the system.
- ✔️ The remote keyless entry (fob) stops working reliably.
A Straightforward Guide to Installation
Once you receive your programmed module, installation is a breeze. This is a key reason our service is so popular with DIYers and professional shops alike. No special programming tools are needed.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate Your BCM: The location varies by model (see our fitment list). Common spots include under the driver’s side dash near the steering column, on the firewall, or in a quarter panel.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Then, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your newly programmed BCM in the exact same location and orientation. Securely plug in all the electrical connectors until they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, radio, etc.—to confirm the repair.
Important Post-Installation Information
In most cases, this module is 100% plug-and-play. However, on some GM vehicles, a couple of simple relearn procedures may be necessary if you notice a warning light after installation. These are standard procedures after a BCM replacement.
- Airbag System Sync: If the airbag light is on, a technician with a professional scan tool will need to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure your brake lights and traction control system function correctly.

Frequently Asked Questions
How does this programming service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, we extract the vehicle-specific data and flash it onto the replacement module. We then ship the ready-to-install BCM back to you.
Will I need to have this programmed by a dealer?
No. The entire point of our service is to avoid dealer programming. Because we clone your original data, the replacement module is plug-and-play, saving you hundreds of dollars in fees and hassle.
What is the turnaround time?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. You will receive a tracking number as soon as it ships.
Do I need to send my keys?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, which we transfer during the cloning process. Your existing keys will work seamlessly.
Is there a core charge for this 2015 Corvette BCM?
No, there is no core charge. You can keep your original, non-working module. The price you see is the final price for the part and the programming service.
