Restore Your Vehicle’s Electrical System with a Pre-Programmed BCM
Are you dealing with frustrating and unpredictable electrical issues in your 2015 Chevrolet Suburban 1500? Problems like flickering lights, malfunctioning power windows and locks, a haywire security system, or even a no-start condition can often be traced back to a single culprit: a failing Body Control Module (BCM). As the central computer for your vehicle’s body electronics, a faulty BCM can create a cascade of problems that are difficult to diagnose. This isn’t just an annoyance; it’s a matter of safety and reliability.
We offer a straightforward and dependable solution. This is a replacement BCM, compatible with part number 13594769 and others, that comes fully programmed with your vehicle’s specific data. By cloning the information from your original BCM, we deliver a true plug-and-play module. This process eliminates the need for expensive dealership visits for programming, saving you significant time, money, and hassle.
How Our Simple Cloning Service Works
Getting your vehicle back to 100% is easy. After you place your order, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our experienced technicians will transfer all the critical vehicle data—including VIN, mileage, and key information—to the replacement module. We then ship the ready-to-install BCM back to you with tracking information. This ensures seamless integration with your vehicle’s existing systems.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Sierra 1500 with a classic BCM failure story. The radio would turn on by itself, the dome lights would stay on draining the battery, and the power locks worked intermittently. They had already replaced the battery twice. After a quick diagnostic scan showed multiple communication errors (U-codes) pointing to the BCM, we confirmed the module was failing internally. Instead of a costly dealer replacement, we provided our programming service. The customer installed the cloned BCM in their driveway in under an hour, and every single electrical gremlin was gone. It’s a common scenario I’ve seen hundreds of times in my 20+ years on the job.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights
- ✔ Power windows, door locks, or mirrors not working correctly
- ✔ The security system or keyless entry is failing
- ✔ The radio or infotainment screen behaves strangely
- ✔ Unexplained battery drain or parasitic draw
- ✔ Instrument cluster warnings for various systems
- ✔ Communication error codes, particularly U-codes like U0140, U0155, or U0164
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On most compatible trucks and SUVs like the 2015 Suburban 1500, the BCM is located under the driver’s side of the dashboard, near the steering column.
- ✔ Remove Trim Panels: You may need to remove a lower dash panel or knee bolster to gain access. These are typically held by a few screws or clips.
- ✔ 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 BCM: Mount the replacement BCM and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- ✔ Reassemble and Reconnect: Reinstall any trim panels you removed and reconnect the negative battery terminal.
- ✔ Perform Post-Install Checks: Start the vehicle and test all body functions—lights, windows, locks, radio, etc. Note the potential post-install procedures below.
Important Post-Installation Notes
While our programming makes this a plug-and-play repair, some GM vehicles may require a couple of simple relearn procedures for full system harmony:
- Airbag System Sync: If your airbag warning light is on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a professional scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure proper function of the brake lights and traction control system.

After your purchase, you’ll ship your original BCM to us. We extract its unique data and transfer it to the replacement module. We then ship the fully programmed, ready-to-install BCM back to you. This ensures it works perfectly with your vehicle’s specific configuration.
No. The module you receive will be pre-programmed with your vehicle’s data from your original BCM. It is designed to be a plug-and-play installation, with no additional dealer programming required.
In some cases, the new BCM needs to be synced with the airbag system’s SDM. This is a simple procedure called “Setup SDM Primary Key in BCM” that can be performed by a qualified technician with a professional scan tool.
No, there is absolutely no core charge. You can keep your original module after sending it in for data cloning.
Common signs include multiple, unrelated electrical failures (lights, locks, windows), security system faults, and communication error codes (U-codes) found with a scanner. While these are strong indicators, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause.
