Description

The SH-ECM-3224 is an input/output (I/O) device that interconnects via the Controller Area Network (CAN), to other electronic control modules (ECMs) in a vehicle. It typically interconnects the loom/dash controls with the various body control functions directly and via the other ECMs. Its compactness makes it easy to install in the vehicle cab, close to the dashboard I/Os and the chassis fuse-box loom. A graphical user interface (touch screen) could be co-located for driver access and status reporting. I/Os can be configured to control and provide power to indicators, wipers, headlights, fans and numerous other loads in the vehicle. The SH ECMs are interchangeable; keeping the harness standardized thus enhancing implementation and maintainability. It may also be deployed as a stand-alone general purpose/special function controller. A sufficient number of ECMs strategically deployed throughout a vehicle, substantially simplifies the wire harness design and eliminates any need for fuse and relay circuits.
