INPUT/OUTPUT SIGNAL CHART

SYSTEM DESCRIPTION

• The engine protection control at low engine oil pressure warns the driver of a decrease in engine oil pres-

sure by the oil pressure warning lamp a before the engine becomes damaged.

• When detecting a decrease in engine oil pressure at an engine speed less than 1,000 rpm, ECM transmits

an oil pressure warning lamp signal to the combination meter.The combination meter turns ON the oil pres-

sure warning lamp, according to the signal.

INPUT/OUTPUT SIGNAL CHART

Input

*: This signal is sent to the ECM via the CAN communication line.

Output

*: This signal is sent to the combination meter via the CAN communication line.

SYSTEM DESCRIPTION

The fuel filler cap warning system alerts the driver to the prevention of the fuel filler being left uncapped and

malfunction occurrences after refueling, by turning ON the fuel filler cap warning display on the combination

meter.

ECM judges a refueled state, based on a fuel level signal transmitted from the combination meter.

When a very small leak is detected through the EVAP leak diagnosis performed after judging the refueled

state, ECM transmits a fuel filler cap warning display signal (request for display ON) to the combination meter

via CAN communication. 

When receiving the signal, the combination meter turns ON the fuel filler cap warning display.

CAUTION:

Check fuel filler cap installation condition when the fuel filler cap warning display turns ON.

The fuel filler cap warning lamp tunes OFF, according to any condition listed below:

• Reset operation is performed by operating the meter control switch on the combination meter. Refer to 

MWI-

20, "Switch Name and Function"

.

- When the reset operation is performed, the combination meter transmits a fuel filler cap warning reset signal

to ECM via CAN communication. ECM transmits a fuel filler cap warning display signal (request for display

OFF) to the combination meter via CAN communication. When receiving the signal, the combination meter

turns OFF the fuel filler cap warning display.

• EVAP leak diagnosis result is normal.

• Fuel refilled.

• DTC erased by using CONSULT.

NOTE:

MIL turns ON if a malfunction is detected in leak diagnosis results again at the trip after the fuel filler cap warn-

ing display turns ON/OFF.

SYSTEM

*: ECM determines the start signal status by the signals of engine speed and battery voltage.

SYSTEM DESCRIPTION

This system improves engine operation when the air conditioner is used.

Under the following conditions, the air conditioner is turned off.

• When the accelerator pedal is fully depressed.

• When cranking the engine.

• At high engine speeds.

• When the engine coolant temperature becomes excessively high.

• When operating power steering during low engine speed or low vehicle speed.

• When engine speed is excessively low.

• When refrigerant pressure is excessively low or high.
