ACTIVE TEST MODE
COOLING FAN
[LOW/HI/OFF]×
Indicates the control condition of the
cooling fans (determined by ECM
according to the input signal).
LOW ... Operates at low speed.
HI ... Operates at high speed.
OFF ... Stopped
EGR VOL CON/V [step]×
Indicates the EGR volume control value
computed by the ECM according to the
input signals.
The opening becomes larger as the
value increases.
INT/A VOLUME [mg/]
The intake air volume computed from the
mass air flow sensor signal is displayed.
BARO SEN [kPa]××
The barometric pressure (determined by
the signal voltage from the absolute pres-
sure sensor built into the ECM) is dis-
played.
INT/M PRES SE [kPa]
Turbocharger boost (determined by the
signal voltage from the turbocharger
boost sensor) is displayed.
CYL COUNT [1/2/3/4]
The cylinder being injected is displayed.
1 ... Cylinder No.1 is injected.
2 ... Cylinder No.2 is injected.
3 ... Cylinder No.3 is injected.
4 ... Cylinder No.4 is injected.
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. [Hz] or

TROUBLE DIAGNOSIS

*:Leaving cooling fan OFF with CONSULT-II while engine is running may cause the engine to overheat.
REAL TIME DIAGNOSIS IN DATA MONITOR MODE
CONSULT-II has two kinds of triggers and they can be selected by touching “SETTING” in “DATA MONITOR”
mode.
1. “AUTO TRIG” (Automatic trigger):
–The malfunction will be identified on the CONSULT-II screen in
real time.
In other words, DTC will be displayed if the malfunction is
detected by ECM.
At the moment a malfunction is detected by ECM, “MONITOR”
in “DATA MONITOR” screen is changed to “Recording Data ...
xx%” as shown in the figure, and the data after the malfunction
detection is recorded. Then when the percentage reached
100%, “REAL-TIME DIAG” screen is displayed. If “STOP” is
touched on the screen during “ Recording Data ... xx%”, “REAL-
TIME DIAG” screen is also displayed.
The recording time after the malfunction detection and the recording speed can be changed by “TRIG-
GER POINT” and “Recording Speed”. Refer to CONSULT-II OPERATION MANUAL.
2. “MANU TRIG” (Manual trigger):
–DTC will not be displayed automatically on CONSULT-II screen
even though a malfunction is detected by ECM.
DATA MONITOR can be performed continuously even though a
malfunction is detected.
Use these triggers as follows:
1. “AUTO TRIG”
–While trying to detect the DTC by performing the DTC Confirma-
tion Procedure, be sure to select to “DATA MONITOR (AUTO
TRIG)” mode. You can confirm the malfunction at the moment it
is detected.
–While narrowing down the possible causes, CONSULT-II should be set in “DATA MONITOR (AUTO
TRIG)” mode, especially in case the incident is intermittent.
When you are inspecting the circuit by gently shaking (or twisting) the suspicious connectors, components
and harness in the DTC Confirmation Procedure, the moment a malfunction is found the DTC will be dis-
played. Refer to GI-23, "
How to Perform Efficient Diagnosis for an Electrical Incident" , “INCIDENT SIMU-
LATION TESTS”.
2. “MANU TRIG”
