METER SYSTEM
System Diagram
System Description
COMBINATION METER- The combination meter receives the signals that are required to control the operation of each meter gauge, indicator lamp/warning lamp, and information display from each unit, switch, and sensor.
- The combination meter is equipped with the drive computer function. Using the signal obtained from each unit, switch, and sensor, the combination meter displays warnings and information to the information display.
- The combination meter incorporates a buzzer function that sounds an audible alarm with the integrated buzzer device. Refer to System Description for details.
- The combination meter integrates the meter circuit check function, the dot matrix check function that checks the information display operation, and the segment check function that checks the shift position indicator operation.
- The combination meter integrates the diagnosis function, and it can perform a diagnosis using CONSULT‐III.
