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
WCS-3, "WARNING CHIME SYSTEM : 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.
