Restore Your Vehicle’s Functionality and Peace of Mind
Are you battling bizarre electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a horn that won’t quit, or a car that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can turn your daily drive into a frustrating guessing game. Dealerships will quote you a hefty price for a new module plus mandatory programming fees. We offer a smarter, more affordable solution.
This is a comprehensive cloning service for your Programmed GM BCM 13506935. Instead of dealing with the expense and hassle of dealership programming, you simply send us your original BCM. Our expert technicians will perform a full data transfer—including your vehicle’s VIN, mileage, and key-specific information—to this replacement module. We then ship it back to you, ready for immediate installation. It’s a true plug-and-play fix that gets you back on the road without the need for expensive scan tools or a trip to the dealer.
A Technician’s Notebook
I remember a 2015 Sierra 1500 that came into the shop with a classic case of “electrical gremlins.” The owner was at his wit’s end. The instrument cluster would randomly go dark, the radio would shut off, and sometimes the truck just wouldn’t crank. Another shop had already replaced the battery and alternator to no avail. After hooking up my diagnostic scanner, I saw a string of U-codes (communication errors), all pointing back to a network issue. The common denominator was the BCM. By testing the power and ground circuits to the module, we confirmed it was failing internally. We performed a BCM clone, and the replacement unit solved every single issue. This is why a proper diagnosis and a correctly programmed module are critical.
Is Your GM Vehicle Showing These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely cause. Look out for Diagnostic Trouble Codes (DTCs) like U0140, U0155, or B1001.
- ✔ Erratic or non-functional power windows, locks, and mirrors
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all
- ✔ The security system light stays on, preventing the engine from starting
- ✔ Horn honking randomly or not working when needed
- ✔ Instrument cluster gauges behaving erratically or going completely dead
- ✔ Communication errors with other vehicle modules (U-codes)
- ✔ Wipers activating on their own or not responding
A Straightforward Guide to Your BCM Installation
Once you receive your pre-programmed module from us, the installation is simple. The location of the BCM varies by model (e.g., under the steering column, behind the dash, or in a kick panel), so always confirm the location for your specific vehicle.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Original BCM: Find the BCM in your vehicle. It’s a black plastic box with several large electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors. Note their orientation. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, programmed BCM in the same location. Reconnect all electrical connectors securely into their correct slots.
- Reconnect Power: Reattach the negative battery terminal.
- Test Functionality: Start the vehicle and test all body functions—lights, windows, locks, wipers, etc.—to ensure everything is working correctly.
Important Post-Installation Information
Our cloning service for the Programmed GM BCM 13506935 is designed to be as seamless as possible. However, in some cases, vehicle systems may require a quick sync-up procedure after the new module is installed.
- Airbag System Sync: If the airbag warning light is illuminated after installation, it means the BCM and the Sensing and Diagnostic Module (SDM) need to be re-synced. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On certain models, the brake pedal position sensor may need to be recalibrated to ensure the brake lights and stability control systems function as intended.
Disclaimer: Vehicle systems vary. For detailed procedures specific to your make and model, we always recommend consulting a factory service manual or a certified automotive technician.
