Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM
Are you battling frustrating electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a car that refuses to start can all point to a single culprit: 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 wide array of confusing and disruptive problems. This replacement Body Control Module, corresponding to part number 15837419 and its alternatives, is the definitive solution to restore full functionality and peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Vehicle security system engaging randomly or preventing the car from starting.
- ✔ Horn, wipers, or radio behaving unpredictably.
- ✔ Dashboard warning lights illuminating for no reason.
- ✔ Inability for a diagnostic scan tool to communicate with various vehicle systems.
Why Choose Our GM Programmed BCM?
The biggest hurdle in replacing a BCM is the need for expensive, dealer-specific programming. Our solution eliminates that step entirely. We take the hassle and high cost out of the repair by pre-programming this module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures that the BCM has the latest software from GM and is configured for the exact options your vehicle was built with. For most installations, this makes the process as simple as swapping the part, saving you a trip to the dealership and significant labor costs. This is a reliable, direct-fit solution for a wide range of GM vehicles, including the Chevrolet Impala, GMC Acadia, Chevrolet Tahoe, and GMC Savana vans.
Installation and Post-Install Notes
While this module is designed for straightforward installation, some vehicles may require simple post-installation relearn procedures. These are not full programming steps but are sometimes necessary to sync the new BCM with other modules in your vehicle.
- Airbag System Sync: If your airbag warning light is on after installation, a technician will need to perform a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This is only required if the light appears.
- 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.
We handle the critical programming; you or your mechanic handle the simple installation. There is no core charge, so you can keep your old part.
