Restore Full Electronic Functionality to Your Vehicle
Is your Cadillac ATS, XTS, Chevrolet Sonic, or Impala suffering from bizarre and frustrating electrical issues? Intermittent power windows, flickering lights, a malfunctioning security system, or even a no-start condition can often be traced back to a single component: a failing 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 a cascade of problems that are difficult to diagnose. This replacement BCM, part number 13589093, is the definitive solution to restore your vehicle’s performance and reliability.
Why Choose Our Programmed Body Control Module Service?
Replacing a BCM isn’t as simple as swapping the part. Modern BCMs are coded specifically to your vehicle’s VIN, key data, and optional features. A new module from the dealership requires expensive and complex on-vehicle programming. Our unique cloning service eliminates this step entirely. We transfer the critical data from your original, failing BCM directly onto this replacement unit. The result is a true plug-and-play module, ready for installation right out of the box, saving you hundreds of dollars in dealership fees and programming labor. This is the most efficient and cost-effective way to get your car back on the road.
From the Diagnostic Bay
We had a 2014 Chevy Sonic come into the shop with a laundry list of complaints. The owner said the radio would turn on by itself, the driver’s side window wouldn’t go down, and the remote key fob worked only half the time. A scan showed multiple communication errors with no clear cause. Instead of chasing electrical gremlins for hours, we went straight to the BCM. After installing one of our pre-programmed modules, every single issue was resolved instantly. Itās a perfect example of how a single failing module can mimic a dozen different problems, and how the right part makes for a quick and permanent fix.
Is Your BCM Failing? Common Symptoms
- ā Power windows, door locks, or mirrors operating erratically or not at all.
- ā Interior or exterior lights (headlights, taillights, dome lights) flickering, staying on, or not turning on.
- ā The vehicle’s security system or alarm malfunctioning or falsely triggering.
- ā Remote keyless entry (key fob) not working correctly.
- ā Dashboard warning lights appearing for seemingly unrelated systems.
- ā The engine cranks but refuses to start due to security system communication failure.
- ā Wipers or horn activating unexpectedly.
The Simple Mail-In Cloning Process
Our service is designed for your convenience. After you place your order, we will contact you with clear, step-by-step instructions for shipping your original BCM to our facility. Once we receive it, our technicians will perform a full data transfer to the replacement module. We then ship both your original module and the ready-to-install replacement back to you. This process ensures all your vehicle’s specific settings, key programming, and VIN information are perfectly preserved.
Installation and Post-Install Notes
Installation is straightforward: simply disconnect the battery, locate and remove your old BCM, and install the new one. While our Programmed Body Control Module is designed to be plug-and-play, some GM vehicles may require minor recalibration procedures after the new module is connected. These are simple procedures that can often be done with a high-end diagnostic tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the systems. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
How does the cloning service work?
After you purchase, we will provide instructions to mail your original BCM to us. We extract the vehicle-specific data (like VIN and key information) and flash it onto the replacement module. We then ship the plug-and-play replacement back to you.
Do I need to send my keys with the module?
No, you do not need to send your keys. All the necessary key data is stored within your original BCM, and we transfer that information directly. Your existing keys will work seamlessly with the new module.
Is this a simple DIY installation?
For someone with moderate mechanical skill, yes. The main task is locating and physically swapping the module. Since our unit is pre-programmed, you avoid the complex computer work. However, always disconnect the battery before starting and consult a service manual if you are unsure.
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 (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ can be performed with a professional scan tool to resolve this.
What is the turnaround time for the programming service?
We typically program and ship your replacement module within 1-2 business days of receiving your original BCM. We will provide you with a return tracking number as soon as it ships.
