< SYSTEM DESCRIPTION >[HR16DE]
SYSTEM
*: When detecting a normal engine oil pressure, ECM turns OFF the oil pressure warning lamp.
FUEL FILLER CAP WARNING SYSTEM

FUEL FILLER CAP WARNING SYS TEM : System DescriptionINFOID:0000000012431327
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.
