WORK ITEM DESCRIPTION USAGE
ENTER INJCTR CALIB DATA
● Injector adjustment value is written onto ECM memory. When performing Injector Adjust-
ment Value Registration.
INJ ADJ VAL CLR
● Injector adjustment value stored in ECM is initialized. Before changing injector adjust-
ment value stored in ECM, it is
recommended to perform this
work item.
Freeze frame data item Description
DIAG TROUBLE CODE
[PXXXX]
● The engine control component part/control system has a trouble code, it is displayed as “PXXXX”.
(Refer to EC-1458, "
INDEX FOR DTC" .)
CAL/LD VALUE [%]
● The calculated load value at the moment a malfunction is detected is displayed.
COOLANT TEMP [°C] or
[°F]
● The engine coolant temperature at the moment a malfunction is detected is displayed.
ENGINE SPEED [rpm]
● The engine speed at the moment a malfunction is detected is displayed.
VEHICL SPEED [km/h] or
[mph]
● The vehicle speed at the moment a malfunction is detected is displayed.
INT MANI PRES [kPa]
● The intake manifold pressure at the moment a malfunction is detected is displayed.

CONDITION SPECIFICATION
CKPS·RPM (TDC) [rpm] ××
● The engine speed computed from the
crankshaft position sensor signal is dis-
played.
COOLAN TEMP/S
[°C] or [°F]
××
● The engine coolant temperature (deter-
mined by the signal voltage of the engine
coolant temperature sensor) is displayed.
When the engine coolant temper-
ature circuit is open or short, ECM
enters fail-safe mode. The engine
coolant temperature determined
by the ECM is displayed.
VHCL SPEED SE
[km/h] or [mph]
××
● The vehicle speed computed form the
vehicle speed sensor signal is displayed.
FUEL TEMP SEN
[°C] or [°F]
××
● The fuel temperature (determined by the
signal voltage of the fuel pump tempera-
ture sensor) is displayed.
ACCEL POS SEN [V] ××
● The accelerator pedal position sensor 1
signal voltage is displayed.
These signals are converted by
ECM internally. Thus, they differ
from ECM terminals voltage.
ACCEL SEN 2 [V] ××
● The accelerator pedal position sensor 2
signal voltage is displayed.
ACT CR PRESS [MPa] ××
● The Fuel rail pressure (determined by the
signal voltage of the fuel rail pressure
sensor) is displayed.
BATTERY VOLT [V] ××
● The power supply voltage of ECM is dis-
played.
P/N POSI SW [ON/OFF] ××
● Indicates [ON/OFF] condition from the
park/neutral position switch signal.
