Restore Full Electrical Function to Your Vehicle
Is your Buick LaCrosse, Chevy Volt, or Cadillac SRX suffering from strange and unpredictable electrical problems? Flickering lights, malfunctioning power windows, a security system that acts on its own, or warning lights that won’t go away are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating issues. This listing offers a simple, effective solution: a replacement BCM, part number 13582688, that is professionally programmed with your vehicle’s original data, making installation a breeze.
From the Diagnostic Bay
We recently had a 2012 Buick LaCrosse come into the shop with a list of bizarre symptoms. The owner reported that the interior lights would stay on, the radio would randomly change stations, and the car wouldn’t start intermittently. He had already replaced the battery and checked the alternator. After connecting our diagnostic scanner, we saw multiple communication errors pointing towards a network failure. We traced the issue to the BCM, which was failing internally and corrupting the data bus. Instead of a costly and time-consuming trip to the dealer for a new module and programming, we used our cloning service. By transferring the data from his original faulty unit to a quality replacement, we had him back on the road the next day with all electrical systems functioning perfectly. It’s a common scenario that highlights the importance of a correctly functioning 2011-2012 LaCrosse BCM.

Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional headlights, taillights, or interior lights.
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Vehicle security system engaging randomly, causing the alarm to sound or preventing the car from starting.
- ✔ False warning lights appearing on the dashboard (e.g., ABS, Airbag, Check Engine).
- ✔ Complete no-start condition where the starter does not engage.
- ✔ Communication issues with diagnostic scan tools.
- ✔ Problems with the climate control or radio functions.
Post-Installation Procedures
While our programming service makes this a plug-and-play part, some GM vehicles may require minor recalibration procedures after installation. These are simple tasks that can often be performed with a high-quality bidirectional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is required. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function correctly.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, wipers, security system, and climate controls. It acts as a central hub for these electronic features.
Why do I have to send you my original BCM?
Your original BCM contains unique data specific to your vehicle, including the VIN, key fob information, and settings for various options. By cloning this data to the replacement module, we make it a true plug-and-play part, eliminating the need for expensive dealership programming.
Is this BCM difficult to install?
Physically, the BCM is usually located in an accessible spot like the driver’s or passenger’s side kick panel. Installation typically involves disconnecting the battery, unplugging a few electrical connectors, and swapping the modules. Since our unit is pre-programmed, no further computer work is needed.
What if the airbag light comes on after I install it?
This is a known possibility on some GM vehicles. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module. A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
How long does the entire process take?
Once we receive your original module, our programming service is typically completed within 24-48 business hours. The total time will depend on shipping speeds to and from our facility. We always ship the programmed module back to you with tracking.
