COMBINATION METER

• The combination meter receives the information required to control the operation of each gauge, indicator/

warning lamp, and information display via CAN communication from each unit, each switch, and sensor.

• The combination meter incorporates a trip computer that displays, warnings and information on the informa-

tion display according to the information received from various units.

• The combination meter incorporates a buzzer function that sounds an audible alarm with the integrated

buzzer device. Refer to

WCS-6, "WARNING CHIME SYSTEM : System Description"

for further details.

• The combination meter incorporates a diagnosis function that allows the technician to perform diagnoses

with CONSULT-III.

• The combination meter integrates the meter circuit check function and the segment check function that

checks the information display operation.

SPEEDOMETER : System Description

INFOID:0000000005883853

MODELS WITH ABS

• The ABS actuator and electric unit (control unit) transmits a vehicle speed signal to the combination meter

via CAN communication.

• The combination meter indicates a vehicle speed to the speedometer, based on the vehicle speed signal

received from the ABS actuator and electric unit.

A/T MODELS WITHOUT ABS

• TCM transmits a vehicle speed signal to the combination meter via CAN communication.
• The combination meter indicates a vehicle speed to the speedometer, based on the vehicle speed signal

received from TCM.

M/T MODELS

• The vehicle speed sensor transmits a vehicle speed sensor signal to the combination meter.
• The combination meter indicates a vehicle speed to the speedometer, based on the vehicle speed sensor

signal received from vehicle speed sensor.

TACHOMETER : System Description

INFOID:0000000005883855

• ECM converts the pulse signal provided by the crankshaft position sensor to an engine speed signal and

transmits it to the combination meter via CAN communication.

• The combination meter indicates the engine speed to the tachometer according to the engine speed signal

received via CAN communication.
