Main characteristics
The CAN system is used to transmit control signals for the input/output of the communication circuit of the instrument cluster, sensors, warning lights and indicator lights.
LEDs are used for all indicators installed in the instrument cluster.
The information display, which includes the clock, audio system and air conditioning system display, is located in the center of the instrument panel. It also includes a drive information system, depending on the vehicle's equipment.
A fanfare-type sound signal is used.
The control devices and emergency signal lamps are listed in Table 7.4, for the specification of the control devices see Table 7.5.
