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.

Reset Operation

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

• Reset operation is performed by operating the meter mode switch on the combination meter.

- 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.

ON BOARD DIAGNOSTIC (OBD) SYSTEM

Diagnosis Description

INFOID:0000000010094844

This system is an on board diagnostic system that records exhaust emission-related diagnostic information

and detects a sensors/actuator-related malfunction. A malfunction is indicated by the malfunction indicator

lamp (MIL) and stored in ECU memory as a DTC. The diagnostic information can be obtained with the diag-

nostic tool (GST: Generic Scan Tool).

GST (Generic Scan Tool)

INFOID:0000000010094845

When GST is connected with a data link connector equipped on the vehicle side, it will communicate with the

control unit equipped in the vehicle and then enable various kinds of diagnostic tests. Refer to 

EC-127, "Diag-

nosis Description"

.

NOTE:

Service $0A is not applied for regions where it is not mandated.
