TROUBLE DIAGNOSIS

*: For QR25DE engine models
NOTE:
Any monitored item that does not match the vehicle being diagnosed is deleted from the display automatically.
DATA MONITOR (SPEC) MODE
Monitored Item
VHCL SPD CUT*
[NON/CUT]

Indicates the vehicle cruise condition.
NON: Vehicle speed is maintained at the
ASCD set speed.
CUT: Vehicle speed increased to excessively
high 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 compared with the ASCD set speed, and
ASCD operation is cut off.
AT OD MONITOR
[ON/OFF]

Indicates [ON/OFF] condition of A/T O/D
according to the input signal from the TCM.
For M/T models, always “OFF” is
displayed.
AT OD CANCEL
[ON/OFF]

Indicates [ON/OFF] condition of A/T O/D can-
cel signal sent from the TCM.
For M/T models, always “OFF” is
displayed.
CRUISE LAMP*
[ON/OFF]

Indicates [ON/OFF] condition of CRUISE lamp
determined by the ECM according to the input
signals.
SET LAMP*
[ON/OFF]

Indicates [ON/OFF] condition of SET lamp
determined by the ECM according to the input
signals.
Voltage [V]

Voltage, frequency, duty cycle or pulse width
measured by the probe.

Only “#” is displayed if item is
unable to be measured.

Figures with “#”s are temporary
ones. They are the same figures
as an actual piece of data which
was just previously measured. Frequency

ENG SPEED [rpm]×

Indicates the engine speed computed
from the signals of the crankshaft posi-
tion sensor (POS) and camshaft position
sensor (PHASE).
MAS A/F SE-B1 [V]××

The signal voltage of the mass air flow
sensor specification is displayed.
When engine is running specification
range is indicated.
B/FUEL SCHDL
[msec]

“Base fuel schedule” indicates the fuel
injection pulse width programmed into
ECM, prior to any learned on board cor-
rection.

When engine is running specification
range is indicated.
A/F ALPHA-B1 [%]×

The mean value of the air-fuel ratio feed-
back correction factor per cycle is indi-
cated.
When engine is running specification
range is indicated.

This data also includes the data for the
air-fuel ratio learning control.

ASCD INDICATOR

ASCD INDICATORPFP:24814
Component DescriptionEBS01FAT
ASCD indicator lamp illuminates to indicate ASCD operation status. Lamp has two indicators, CRUISE, SET,
and is integrated in combination meter.
CRUISE indicator illuminates when MAIN switch on ASCD steering switch is turned ON to indicated that
ASCD system is ready for operation.
SET indicator illuminates when following conditions are met.

CRUISE indicator is illuminated.

SET/COAST switch on ASCD steering switch is turned ON while vehicle speed is within the range of
ASCD setting.
SET indicator remains lit during ASCD control.
Refer to EC-529, "
AUTOMATIC SPEED CONTROL DEVICE (ASCD)" for the ASCD function.
CONSULT-II Reference Value in Data Monitor ModeEBS01FAU
Specification data are reference value.
