General Description, Electrical System

This vehicle has a multiplex electrical system. By transmitting multiple electronic messages through the same wire, a multiplex system reduces the number of interconnected wires, allows for more precise control of the electrical system, and makes it easier and quicker to diagnose electrical faults and add optional equipment.

In addition, the wiring harnesses are developed for the maximum number of options, meaning that space for additional wires is available within the wiring harness regardless of the number of optional features on the vehicle. This design provides a cleaner main harness and is meant to eliminate the need for wiring overlays.

Traditional power distribution devices are replaced with electronic control modules (ECUs). These coordinate power to outputs such as lighting, displays, gauges, and indicators and control power distribution by monitoring inputs such as sensors and switches. Power is supplied by the vehicle power distribution module (VPDM).

The ECUs also continuously monitor the status of all input devices and transmit messages over multiple control area networks (CANs), reducing the number of sensors required for operation.
