Restore Your Vehicle’s Electrical System with a Programmed BCM

Are you experiencing a cascade of bizarre electrical issues in your Buick LaCrosse, Chevy Volt, or Cadillac SRX? Problems like power windows that won’t operate, intermittent dashboard lights, a security system that acts up, or even a no-start condition can often be traced back to a single, critical component: the Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can create frustrating and difficult-to-diagnose problems. This listing offers a straightforward, effective solution: a replacement BCM programmed specifically for your vehicle, using the data from your original module.

From the Diagnostic Bay
We had a 2012 Equinox come into the shop with a laundry list of complaints from the owner. The dome lights would flicker, the radio would randomly shut off, and the key fob worked only half the time. The owner had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication errors pointing towards the BCM. Instead of sending them to a dealership for a costly new module and programming, we performed a cloning service just like this one. By transferring the data from the old, failing unit to a quality replacement, we had the Equinox back on the road with all its electronics functioning perfectly in a fraction of the time and at a fraction of the cost. It’s a testament to how a single module can cause widespread issues and how the right service can provide a simple fix.

Symptoms of a Failing Body Control Module

  • ✔ Erratic or non-functional power windows, door locks, and mirrors.
  • ✔ Interior or exterior lights staying on, flickering, or not working at all.
  • ✔ Malfunctioning security system or keyless entry.
  • ✔ Warning lights (like Airbag or ABS) appearing on the dashboard without a clear cause.
  • ✔ The vehicle’s horn sounding randomly.
  • ✔ Intermittent no-start or crank-no-start conditions.
  • ✔ Problems with the radio, climate control, or other interior accessories.

Why Choose Our Programmed 2011-2012 LaCrosse BCM Service?

This service provides a direct replacement for your faulty BCM without the need for additional dealer intervention. By cloning your original data, the replacement module becomes a true plug-and-play component, seamlessly integrating with your vehicle’s other systems. This process preserves your original key programming and vehicle settings, ensuring a smooth and correct repair. This module is compatible with a wide range of GM vehicles and replaces numerous part numbers, including 13579004, 13580198, 13583450, 13586856, 13501737, and more.

Post-Installation Information

While our goal is a 100% plug-and-play experience, some vehicle systems may require a simple sync procedure after installation.

  • Airbag System Sync: If the airbag warning light is illuminated after you install the BCM, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. This is a simple sync that can be performed with a professional-grade diagnostic tool.
  • Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper function of the brake lights and traction control system.

Always consult a factory service manual or a qualified technician if you are unsure about any post-installation steps. Getting your 2011-2012 LaCrosse BCM from us is the most reliable way to solve your vehicle’s electrical issues.

Frequently Asked Questions

What exactly is a Body Control Module (BCM)?

The BCM is a computer in your vehicle that controls and monitors a wide variety of non-engine-related functions. This includes power windows, locks, lights, security systems, wipers, and more. It’s the command center for passenger comfort and convenience electronics.

How does this cloning service work?

After you purchase, you will ship your original BCM to us. Our technicians will extract the unique data from your module and transfer it to a fully functional replacement BCM. We then ship the programmed replacement back to you, ready for installation.

Do I need to have this programmed by a dealer after I receive it?

No. The purpose of our cloning service is to completely eliminate the need for dealership programming. Because we transfer your vehicle’s original data, the replacement module is plug-and-play.

What happens if my airbag light is on after installation?

In some cases, the new BCM needs to be synchronized with the airbag system’s SDM (Sensing and Diagnostic Module). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure, which will turn off the light.

Is this a guaranteed fix for my vehicle’s electrical problems?

If your vehicle’s issues match the common symptoms of BCM failure and proper diagnosis has pointed to the BCM, this service is an effective solution. However, we always recommend a thorough diagnosis by a qualified technician to confirm the BCM is the root cause before ordering.

Which part numbers does this module replace?

This BCM is a direct replacement for a wide range of part numbers, including 13579004, 13580198, 13582396, 13583450, 13586856, 13582688, 13586278, 13501737, 13501739, 13577924, 13580773, and 13583451.
