REAL TIME DIAGNOSIS IN DATA MONITOR MODE
(RECORDING VEHICLE DATA)
NCEC0034S10
CONSULT-II has two kinds of triggers and they can be selected by
touching “SETTING” in “DATA MONITOR” mode.
1)
“AUTO TRIG” (Automatic trigger):
I
The malfunction will be identified on the CONSULT-II screen in
real time.
In other words, DTC 1st trip DTC and malfunction item 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 at left, and the data after the malfunc-
tion detection is recorded. Then when the percentage reached
is 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 “TRIGGER POINT” and
“Recording Speed”. Refer to CONSULT-II OPERATION
MANUAL.
2)
“MANU TRIG” (Instruction trigger):
I
DTC/1st trip DTC and malfunction item will not be displayed
automatically on CONSULT-II screen even though a malfunc-
tion is detected by ECM.
DATA MONITOR can be performed continuously even though
a malfunction is detected.
Use these triggers as follows:
1)
“AUTO TRIG”
I
While trying to detect the DTC/1st trip DTC by performing the
“DTC Confirmation Procedure”, be sure to select to “DATA
MONITOR (AUTO TRIG)” mode. You can confirm the malfunc-
tion at the moment it is detected.
I
While narrowing down the possible causes, CONSULT-II
should be set in “DATA MONITOR (AUTO TRIG)” mode, espe-
cially in case the incident is intermittent.

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION

CONSULT-II (Cont’d)
EC-76
When you are inspecting the circuit by gently shaking (or twist-
ing) the suspicious connectors, components and harness in
the “DTC Confirmation Procedure”, the moment a malfunction
is found the DTC/1st trip DTC will be displayed. (Refer to GI
section, “Incident Simulation Tests” in “HOW TO PERFORM
EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT”.)
2)
“MANU TRIG”
I
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.
