Restore Full Functionality to Your GM Vehicle
Are you battling bizarre electrical issues in your Saturn VUE or another GM vehicle? Flickering dashboard lights, power windows with a mind of their own, or a security system that won’t cooperate are all classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s comfort and convenience features, a faulty BCM can turn your daily drive into a frustrating ordeal. This isn’t just an inconvenience; it can affect everything from your interior lighting to your anti-theft system. We offer a dependable, straightforward solution to get your vehicle operating as it should.
This is a direct-fit replacement Body Control Module, part number 15880684, for a wide range of GM vehicles. The best part? Our professional Cloning Service eliminates the need for expensive dealership visits and programming fees. Simply send us your original BCM, and we will transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. When you receive it back, it’s a true plug-and-play installation, pre-configured for your exact vehicle.
From the Diagnostic Bay: The Case of the Haunted SUV
A customer brought in a 2009 Saturn VUE with a list of complaints that sounded like something out of a ghost story. The dome light would randomly turn on while driving, the power locks would cycle on their own, and the radio would occasionally shut off. They had already replaced the battery and checked the main grounds. After hooking up my scan tool, I noticed several communication error codes (U-codes) pointing to the BCM. These modules often fail internally from voltage spikes or simple age, causing them to send erratic commands across the vehicle’s network. By performing a cloning service on a replacement 2008-2010 VUE Body Control Module, we were able to solve all the ‘hauntings’ in a single afternoon without a trip to the dealer for programming. It’s a common failure I’ve seen dozens of times, and this service is the most efficient fix.
Common Signs of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not working at all).
- ✔ The security system or keyless entry system malfunctioning.
- ✔ Dashboard warning lights appearing without a clear cause (e.g., “Service Theft System”).
- ✔ Communication Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other U-series codes stored in the system.
- ✔ Horn sounding unexpectedly or not working when pressed.
A Straightforward Guide to Your BCM Swap
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2008-2010 Saturn VUE, the BCM is typically found in the center dash area. For other models, its location can vary (see fitment list for common locations). You may need to remove a few trim panels to gain access.
- ✔ Disconnect and Remove: Carefully 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 your newly cloned BCM in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
- ✔ Reconnect Power: Re-attach the negative battery terminal.
- ✔ Test and Verify: Start the vehicle and test all body functions: lights, locks, windows, radio, etc. Address any post-install procedures if necessary (see below).
Important Post-Installation Information
With our cloning service, most vehicles will not require any additional steps. However, on some GM models, you may encounter the following:
- Airbag System Sync: If the airbag light is illuminated after installation, a simple “Setup SDM Primary Key in BCM” procedure is needed. This requires a professional-grade scan tool and syncs the BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.

Frequently Asked Questions
How does the Cloning Service work?
After you purchase, we will provide instructions for you to send us your original BCM. Our technicians will extract the vehicle-specific data and transfer it to the replacement module. This makes the new part plug-and-play, saving you from a trip to the dealership.
Why do you need my VIN?
We use your Vehicle Identification Number (VIN) to access the latest official GM software updates for your specific vehicle, ensuring the module we send you has the most current and stable programming available.
Is this a guaranteed fix for my problem?
This module will fix problems directly caused by a faulty BCM. While the symptoms listed are very common for BCM failure, we always recommend a proper diagnosis by a qualified mechanic to rule out other issues like bad wiring or faulty sensors.
Do I need to return my old BCM? What is your core policy?
Yes, you must send us your original module for the cloning service. We always return your original (core) module to you along with the newly programmed replacement. We do not keep your old part.
What tools are needed for the post-install procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a high-level, bidirectional diagnostic scan tool, such as a GM Tech 2, Snap-on, or Autel scanner. Most basic code readers cannot perform these functions.
