*: 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 toGI-24, "
How to Perform Efficient Diagnosis for an Electrical Incident", “INCIDENT SIMU-
LATION TESTS”.

TROUBLE DIAGNOSIS
–If the malfunction is displayed as soon as “DATA MONITOR” is selected, reset CONSULT-II to “MANU
TRIG”. By selecting “MANU TRIG” you can monitor and store the data. The data can be utilized for further
diagnosis, such as a comparison with the value for the normal operating condition.
FUNCTION TEST
This mode is used to inform customers of their vehicle condition of periodic maintenance.
