Programmed 2015 Sierra Denali 2500 BCM Body Control Module 13594692

End the Electrical Chaos in Your GM Vehicle

As a technician with over two decades of experience, I’ve seen it all when it comes to bewildering electrical issues. Your power windows have a mind of their own, the radio cuts out randomly, or you’re greeted by a dashboard lit up like a Christmas tree. These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM), the electronic nerve center of your vehicle. For owners of a 2015 Sierra Denali 2500 BCM and many other GM models, this can be a frustrating and expensive problem to solve—until now.

This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professional cloning service for this BCM, compatible with part numbers like 13594692, 13580690, and others. Simply send us your original module. My team will expertly transfer all the critical vehicle-specific data—including VIN, mileage, and key programming—to this fully tested replacement unit. We then ship it back to you, ready for a true plug-and-play installation. This process eliminates the need for expensive dealership programming and specialized scan tools, saving you significant time and money.

Is Your Vehicle Showing These BCM Failure Signs?

A faulty BCM can cause a wide range of confusing symptoms. If you’re experiencing any of the following, this module is likely the solution you need. Look out for:

• ✔ Erratic or non-functional power windows, door locks, and mirrors.
• ✔ Interior or exterior lights staying on or not working at all.
• ✔ The security system acting up or preventing the engine from starting.
• ✔ Inconsistent operation of the radio, climate controls, or instrument cluster gauges.
• ✔ False warning messages on the driver information center (e.g., “Service Airbag,” “Service StabiliTrak”).
• ✔ Diagnostic trouble codes (DTCs) such as U0140, U0155, or various B-series codes related to body systems.
• ✔ Remote key fob not working correctly.

Your Straightforward BCM Installation Guide

Installing your pre-programmed BCM is a direct process that most DIYers can handle. Here are the general steps. Remember to always consult a service manual for your specific vehicle’s details.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge before starting any electrical work.
2. Locate the BCM: On most trucks and SUVs like the Sierra, Silverado, and Tahoe, the BCM is located under the driver’s side of the dashboard, near the steering column. On sedans like the CTS or XTS, it may be in the dash, firewall, or hinge pillar area.
3. Remove Trim Panels: You will likely need to remove a lower dash panel or kick panel to gain access. These are typically held in by a few screws or plastic clips.
4. Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
5. Install the New Module: Mount the replacement BCM and securely plug in all the electrical connectors. You should hear a click as they lock into place.
6. Reconnect and Test: Reinstall any trim panels you removed. Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: lights, windows, locks, radio, etc., to confirm the repair.

Important Post-Installation Notes

Our cloning service handles the vast majority of programming needs. However, in some GM vehicles, additional sync procedures may be required after installation:

• Airbag System Sync: If the airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
• Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn might be necessary to ensure brake lights and traction control function correctly.

Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step. And remember, there is NO CORE CHARGE. You can keep your old module.
