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.

DIAGNOSIS SYSTEM (ECM)
ALT DUTY SIG ON/OFF• The control condition of the power generation
voltage variable control (determined by ECM ac-
cording to the input signals) is indicated.
- ON: Power generation voltage variable control is active.
- OFF: Power generation voltage variable control is inactive.
I/P PULLY SPD rpmIndicates the engine speed computed from the in-
put speed sensor signal.
VEHICLE SPEED km/h or mph The vehicle speed computed from the vehicle
speed signal sent from TCM is displayed.
IDL A/V LEARN YET/CMPLT • Displays the condition of Idle Air Volume Learn-
ing.
- YET: Idle air volume learning has not been per-
formed yet.
- CMPLT: Idle air volume learning has already been performed successfully.
TRVL AFTER MIL km or mile Distance traveled while MIL is activated.
ENG OIL TEMP °C or °F The engine oil temperature (determined by the sig-
nal voltage of the engine oil temperature sensor) is
indicated.
A/F S1 HTR(B1) %• Air fuel ratio (A/F) sensor 1 heater control value
computed by ECM according to the input signals.
• The current flow to the heater becomes larger as the value increases.
VHCL SPEED SE km/h or mph The vehicle speed computed from the vehicle
speed signal sent from combination meter is dis-
played.
SET VHCL SPD km/h or mph The preset vehicle speed is displayed.
MAIN SW ON/OFFIndicates [ON/OFF] condition from ASCD MAIN
switch signal.
CANCEL SW ON/OFFIndicates [ON/OFF] condit
ion from CANCEL switch
signal.
RESUME/ACC SW ON/OFF Indicates [ON/OFF] condition from ACCEL/RES
switch signal.
SET SW ON/OFFIndicates [ON/OFF] condition from COAST/SET
switch signal.
BRAKE SW1 ON/OFFIndicates [ON/OFF] condition from ASCD brake
switch signal.
BRAKE SW2 ON/OFFIndicates [ON/OFF] condition of stop lamp switch
signal.
VHCL SPD CUT NON/CUT • Indicates the vehicle cruise condition.
- NON: Vehicle speed is maintained at the ASCD
set speed.
- CUT: Vehicle speed decreased to excessively
low compared with the ASCD set speed, and
ASCD operation is cut off.
LO SPEED CUT NON/CUT • Indicates the vehicle cruise condition.
- NON: Vehicle speed is maintained at the ASCD
set speed.
- CUT: Vehicle speed decreased to excessively low, and ASCD operation is cut off.
AT OD MONITOR ON/OFF Indicates [ON/OFF] condition of CVT O/D accord-
ing to the input signal from the TCM.
AT OD CANCEL ON/OFF Indicates [ON/OFF] condition of CVT O/D cancel
request signal.
