Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your Chevrolet Silverado, GMC Sierra, or Tahoe? Issues like malfunctioning power windows, erratic HVAC controls, a persistent airbag light, or a vehicle that refuses to start can often be traced back to a single component: a failing Body Control Module (BCM). This VIN-programmed BCM, interchangeable with part number 15878753, is the definitive solution to restore your vehicle’s electronic systems to factory-perfect operation without a costly trip to the dealership.
Is Your GM Truck Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors not working or operating intermittently.
- ✔ HVAC system is unresponsive, or the blower motor works sporadically.
- ✔ The airbag warning light is illuminated, often with a DTC B1001 code.
- ✔ The security system acts up, causing no-start or stalling conditions.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on at all.
- ✔ The instrument cluster displays false warnings or loses communication.
The Plug-and-Play Silverado 3500 BCM Solution
This isn’t just a replacement part; it’s a complete, ready-to-install fix. The heart of our service is the pre-installation VIN programming. We load your vehicle’s specific VIN and the latest GM software onto the module before it ships. This ensures that when you receive your Silverado 3500 BCM, it communicates flawlessly with your truck’s other electronic systems, like the engine computer and anti-lock brake module. This critical step eliminates the need for expensive programming tools or dealership appointments, making the repair faster and more affordable.
Built to strict OEM standards, this module provides dependable control over all your vehicle’s body functions. Installation is straightforward, typically located under the driver’s side dashboard. And with our no-hassle policy, there is no core charge—you can keep your old part.
Post-Installation Procedures
While installation is plug-and-play, some vehicles may require a simple sync procedure. If your airbag light remains on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. This re-establishes the secure handshake between the BCM and the airbag system. In some cases, a Brake Pedal Position relearn may also be needed to ensure proper brake light and traction control function. Always consult a service manual for your specific model if you are unsure.
