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 control switch on the combination meter. Refer to
18, "WARNING LAMPS/INDICATOR LAMPS : System Description"
.
- 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.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
Diagnosis Description
INFOID:0000000009947229
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:0000000009947230
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
.
NOTE:
Service $0A is not applied for regions where it is not mandated.
