The Freightliner bulkhead module (BHM) is a key electronic control unit within the truck's multiplexed electrical system. Its primary functions include:
- Acting as a central hub for electrical communication between various modules, such as the engine control module (ECM), transmission control module (TCM), and body control module (BCM).
- Controlling and distributing power to key electrical components, including headlights, taillights, the HVAC system, and interior electronics.
- Facilitating diagnostics by managing data and fault codes from connected systems.
- Supporting efficient operation of the truck's electrical and communication systems by integrating multiple systems into a centralized network.
The BHM enhances reliability and simplifies diagnostics and maintenance by centralizing control over many of the vehicle's electrical functions. Proper maintenance and regular software updates help ensure its optimal performance.
