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 messages 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-5, "WARNING CHIME SYSTEM : System Description"
for further details.
• The combination meter integrates the meter circuit check function and the segment check function that
checks the information display operation.
IPDM E/R
• IPDM E/R reads the ON/OFF signals of the oil pressure switch and transmits the oil pressure switch signal to
the combination meter via BCM with the CAN communication line.
• IPDM E/R is equipped with the diagnosis function. It can perform the operation check of oil pressure warning
lamp with the auto active test and the diagnosis with CONSULT-III.
