OIL PRESSURE WARNING LAMP : System Description

INFOID:0000000005883859

• IPDM E/R reads the ON/OFF signals from the oil pressure switch and transmits the oil pressure switch sig-

nal to the BCM via CAN communication.

• BCM transmits oil pressure switch signal to the combination meter via CAN communication.
• The combination meter turns the oil pressure warning lamp ON (at the time of a reduction in hydraulic pres-

sure)/OFF (except at the time of a reduction in hydraulic pressure) according to the oil pressure switch signal
received via CAN communication.

FUEL GAUGE

The combination meter converts a resistance value of the fuel level sensor unit into voltage to show fuel
remaining quantity on the information display.

Refuel Control

• When the ignition switch is turned from OFF to ON or when all the following operating conditions are satis-

fied, fuel gauge indication speed becomes faster than usual.

• The combination meter judges refuel control, according to the signals below:

SHIFT POSITION INDICATOR

• TCM transmits a shift position signal to the combination meter via CAN communication.
• The combination meter displays a shift position on the vehicle information display when receiving a shift

position signal from TCM.

TRIP COMPUTER

Current Fuel Consumption

The combination meter calculates current fuel consumption based on the following signals, and the calculated
value is displayed on the information display.

MODELS WITH ABS

A/T MODELS WITHOUT ABS

M/T MODELS

NOTE:
• Current fuel consumption on the information display is updated approximately every 0.5 seconds.
• Current fuel consumption on the information display shows 0 l/100km (0 mpg) when vehicle speed is 0 km/h

(0 MPH).

Average Fuel Consumption

The combination meter calculates average fuel consumption based on the following signals, and the calcu-
lated value is displayed on the information display.
