Restore Full Electrical Function to Your Vehicle
Is your 2014-2017 Buick Regal, LaCrosse, or other compatible GM vehicle suffering from bizarre electrical issues? Flickering lights, unresponsive power windows, or random warning messages on the dash are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it malfunctions, it can create a host of frustrating and difficult-to-diagnose problems. This replacement BCM, part number 13590173, is the definitive solution to get your vehicle’s systems operating as they should.
The Plug-and-Play Solution: Our Cloning Service
Replacing a BCM is not as simple as swapping the part. Modern modules are coded specifically to your vehicle’s VIN, security system, and optional features. A new or used module from another vehicle would require expensive and complex programming at a dealership. Our unique cloning service eliminates this step entirely. By sending us your original BCM, we can extract all the critical vehicle-specific data and transfer it directly to this replacement unit. The result is a module that is 100% plug-and-play. Simply install it, and your vehicle will recognize it as the original, retaining all functionality, including your existing keys.
From the Diagnostic Bay
We had a 2015 Buick LaCrosse come into the shop with a complaint of a dead battery every morning. The owner had already replaced the battery and the alternator, but the parasitic drain continued. Standard diagnostic tests were inconclusive. After digging into the data stream, we noticed the BCM wasn’t allowing other modules to go into ‘sleep’ mode after the car was shut off. It was keeping the network awake, slowly draining the battery overnight. A new, programmed Regal Body Control Module (the same unit fits the LaCrosse) solved the issue instantly. This is a classic example of how a faulty BCM can cause symptoms that seem unrelated to its primary function.
Common Symptoms of a Failing Regal Body Control Module
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior dome lights, headlights, or taillights staying on or not turning on.
- ✔ The security system or alarm malfunctioning, or a ‘Service Theft Deterrent System’ message appearing.
- ✔ Instrument cluster gauges behaving strangely or warning lights appearing for no reason.
- ✔ Communication errors when trying to scan the vehicle with a diagnostic tool.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ Wipers or radio turning on by themselves.

Installation and Post-Install Procedures
The BCM is typically located in the driver’s or passenger’s side kick panel or behind the dash. While installation is straightforward, in some cases, minor electronic recalibrations may be needed after the new module is connected. These may include:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the modules.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be necessary to ensure correct brake light operation and traction control functionality.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM cloning service?
Cloning is the process of reading the essential, vehicle-specific data (like VIN, mileage, key information, and security codes) from your original BCM and writing it onto a replacement module. This makes the replacement unit an exact electronic duplicate of the original, ensuring a simple plug-and-play installation without the need for dealership programming.
Why do I need to send you my original module?
Your original module contains the unique data that allows it to communicate with all the other computers in your car. We need your original module to extract this data. Without it, the replacement BCM would not be recognized by your vehicle, and it would not start or function correctly.
Will my existing keys work after installation?
Yes! Because we transfer all the security information from your original BCM, the replacement module will recognize your existing keys immediately. There is no need for a costly key relearn procedure.
How long does the programming service take?
Once we receive your original module, the cloning process is typically completed and shipped back out within 24-48 business hours.
What happens if the airbag light is on after I install the BCM?
In some vehicles, the BCM and the airbag module (SDM) need to be electronically re-synced after a BCM replacement. This is a standard procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any qualified shop with a professional-grade diagnostic tool.
