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/1st trip DTC/2nd trip 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/1st trip DTC/2nd trip DTC will not be displayed automati-
cally 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/1st trip DTC/2nd trip DTC by per-
forming the “DTC Confirmation 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/1st trip
DTC/2nd trip DTC will be displayed. Refer to GI-21, “HOW TO PERFORM EFFICIENT DIGANOSES FOR
AN ELECTRICAL INCIDENT”, “Incident Simulation Tests”.
2.
“MANU TRIG”
–
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.

shown.)
5.
Perform each diagnostic mode according to each service proce-
dure.
For further information, see the GST Operation Manual of the
tool maker.
MODE 4
CLEAR DIAG INFO
This mode can clear all emission-related diagnostic information. This includes:
●
Clear number of diagnostic trouble codes (MODE 1)
●
Clear diagnostic trouble codes (MODE 3)
●
Clear trouble code for freeze frame data (MODE 1)
●

TROUBLE DIAGNOSIS
*1: This signal is converted by ECM internally. Thus, it differs from ECM terminal voltage.
*2: For YD22DDTi engine models
NOTE:
Any monitored item that does not match the vehicle being diagnosed is deleted from the display automatically.

TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
PFP:00006
Description
EBS0138J
Intermittent incidents (I/I) may occur. In many cases, the incident resolves itself (the part or circuit function
returns to normal without intervention). It is important to realize that the symptoms described in the customer's
complaint often do not recur on (1st/2nd trip) DTC visits. Realize also that the most frequent cause of I/I occur-
rences is poor electrical connections. Because of this, the conditions under which the incident occurred may
not be clear. Therefore, circuit checks made as part of the standard diagnostic procedure may not indicate the
specific malfunctioning area.
COMMON I/I REPORT SITUATIONS
Diagnostic Procedure
EBS0138K
1.
INSPECTION START
Erase (1st/2nd trip) DTCs. Refer to
EC-961, "HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFOR-
.
>> GO TO 2.
2.
CHECK GROUND TERMINALS
Check ground terminals for corroding or loose connection.
Refer to GI-21, “HOW TO PERFORM EFFICIENT DIAGNOSES FOR AN ELECTRICAL INCIDENT”, “Circuit
Inspection”, “GROUND INSPECTION”.
OK or NG
OK
>> GO TO 3.
NG
>> Repair or replace.
3.
SEARCH FOR ELECTRICAL INCIDENT
Perform GI-21, “HOW TO PERFORM EFFICIENT DIAGNOSES FOR AN ELECTRICAL INCIDENT”, “Incident
Simulation Tests”.
OK or NG
OK
>> INSPECTION END
NG
>> Repair or replace.
STEP in Work Flow
Situation
II
The CONSULT-II is used. The SELF-DIAG RESULTS screen shows time data other than “0”.
III
The symptom described by the customer does not recur.
IV
(1st/2nd trip) DTC does not appear during the DTC Confirmation Procedure.
VI
The Diagnostic Procedure for XXXX does not indicate the malfunctioning area.
