Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you tired of chasing down bizarre electrical issues in your 2015-2016 GM vehicle? From flickering lights and malfunctioning power windows to a car that simply won’t start, a failing Body Control Module (BCM) can turn your reliable ride into a source of constant frustration. The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can create a cascade of confusing and unpredictable problems. Dealerships often charge a small fortune for a new module, plus expensive programming and calibration fees. We offer a smarter, more affordable solution.
This is a fully tested replacement BCM that comes programmed specifically for your vehicle. How do we do it? We use a simple cloning process. After your purchase, we’ll provide instructions for you to send us your original BCM. Our expert technicians will then transfer all the critical data—including VIN, mileage, and key information—to this replacement module. The result is a true plug-and-play component. You receive a module that is ready for installation right out of the box, eliminating the need for a trip to the dealership. This service for your 2015-2016 GM BCM saves you time, money, and the headache of complex programming procedures.
A Technician’s Notebook
I remember a 2015 Sierra 1500 that came into the shop with a laundry list of complaints. The radio would cut out, the driver’s side window wouldn’t go down, and the dome lights had a mind of their own. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a dozen communication codes (U-codes) pointing to a network failure. Instead of shotgunning parts, I went straight to the BCM. A quick check of the data stream showed erratic voltage outputs. By cloning his original module, we had the truck’s electronics functioning perfectly in a day, without the high cost or wait time of a dealership visit. This is a classic BCM failure scenario I’ve seen hundreds of times.
Is Your Vehicle Showing These Symptoms?
A faulty BCM can manifest in many ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Power windows, locks, or mirrors not working or operating erratically.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ The horn sounding randomly or not working when pressed.
- ✔ Remote keyless entry failing to lock or unlock the doors.
- ✔ “Service Theft Deterrent System” or other warnings on the instrument cluster.
- ✔ Communication Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other U-series codes.
- ✔ A no-start condition where the engine cranks but won’t fire up due to security system issues.
A Straightforward Guide to Installation
Installing your pre-programmed 2015-2016 GM BCM is a direct replacement process. While the exact location varies by model (see fitment list), the steps are generally similar.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most GM trucks and SUVs, the BCM is located under the steering column, behind the lower dash panel. On sedans and coupes, it may be in the LH dash, on the firewall, or even in the rear quarter panel.
- Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the module.
- Disconnect and Remove: 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 Module: Mount the replacement BCM in the same location and reconnect all electrical connectors, ensuring they click securely into place.
- Reconnect Battery: Re-attach the negative battery terminal.
- Test Functionality: Start the vehicle and test all body functions – lights, windows, locks, radio, etc. – to confirm the repair is successful.
Important Post-Installation Notes
Our cloning service handles all the primary programming. However, in some cases, your vehicle may require a simple relearn procedure for specific subsystems to communicate with the ‘new’ BCM. These are not programming steps but rather synchronization functions.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the airbag system with the BCM.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any part of the process.
