Is your vehicle suffering from frustrating electrical problems?
If your Saturn Vue, Chevy Equinox, GMC Acadia, or other compatible GM vehicle is experiencing bizarre electrical behavior, a failing Body Control Module (BCM) is often the culprit. The BCM is the central nervous system for your car’s comfort and convenience features. When it malfunctions, it can create a cascade of issues that are difficult to diagnose, from flickering lights to a car that won’t start. This replacement Body Control Module, part number 15837419, is the definitive solution to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay
We had a 2009 Chevy Traverse come in that the owner described as “possessed.” The dome lights would flash randomly, the radio would turn on and off by itself, and the power locks would cycle while driving. After checking the battery and main grounds, we connected our diagnostic tool and found multiple communication errors pointing towards the BCM. Instead of a costly and time-consuming repair at the dealership, the owner ordered one of our VIN-programmed modules. After a straightforward installation, all the ghostly electrical issues were gone. It’s a common story for a failing BCM.
Common Symptoms of a Failing BCM
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or failing to turn on.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Unexplained warning lights on the instrument cluster (like the airbag or brake light).
- ✔ HVAC (A/C and heater) controls not responding correctly.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ Communication issues with other vehicle modules.

Simply provide us with your vehicle’s VIN (Vehicle Identification Number) during checkout, and our technicians will program the module with the latest, most stable software updates directly from GM. This ensures perfect compatibility with your vehicle’s specific options and eliminates the need for an expensive trip to the dealership for programming.
Post-Installation Information
While we handle the primary programming, some vehicles may require simple relearn procedures after installation. These can include:
- Airbag System Sync: If your airbag light is on after installation, a professional scan tool may be needed to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor relearn might be necessary.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What is a BCM and what does it control?
The Body Control Module (BCM) is a computer that manages many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, wipers, security system, and interior climate controls.
Is this part truly plug-and-play?
Mostly, yes. We pre-program the module to your VIN, which handles 95% of the work. However, as noted, some vehicles may require additional security or sensor relearn procedures with a compatible scan tool after installation.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive and program it with this information.
Will this BCM fit vehicles other than the Saturn Vue?
Yes. This module, identified by part number 15837419 and its interchanges, is compatible with a wide range of GM vehicles including the Chevy Equinox, GMC Acadia, Chevy Impala, Cadillac DTS, and many more. Please check the detailed fitment list to confirm compatibility.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
