REAL TIME DIAGNOSIS IN DATA MONITOR MODE (RECORDING VEHICLE DATA)
Description
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 and malfunction item will be
displayed if the malfunction is detected by ECM.
At the moment a malfunction is detected by ECM, “MONI-
TOR” in “DATA MONITOR” screen is changed to “Recording
Data ... xx%” as shown at right, and the data after the mal-
function 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.

TROUBLE DIAGNOSIS
recording speed can be changed by “TRIGGER POINT” and
“Recording Speed”. Refer to CONSULT-II OPERATION MAN-
UAL.
2.
“MANU TRIG” (Manual trigger):
●
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.
Operation
1.
“AUTO TRIG”
●
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 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, compo-
nents and harness in the “DTC Confirmation Procedure”, the moment a malfunction is found the DTC/
1st trip DTC will be displayed. (Refer to “Incident Simulation Tests” in “HOW TO PERPERFORM EFFI-
CIENT DIAGNOSES FOR AN ELECTRICAL INCIDENT”, GI-21.)
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 fur-
ther diagnosis, such as a comparison with the value for the normal operating condition.

DESCRIPTION
Generic Scan Tool (OBDII scan tool) complying with ISO 15031-4
has 8 different functions explained below.
ISO9141 is used as the protocol.
The name “GST” or “Generic Scan Tool” is used in this service man-
ual.
FUNCTION
GST INSPECTION PROCEDURE
1.
Turn ignition switch OFF.
2.
Connect “GST” to data link connector, which is located under the
driver side dash panel near the fuse box cover.
3.
Turn ignition switch ON.

Diagnostic test mode
Function
MODE 1
READINESS TESTS
This mode gains access to current emission-related data values, including analog inputs
and outputs, digital inputs and outputs, and system status information.
MODE 2
(FREEZE DATA)
This mode gains access to emission-related data value which were stored by ECM during
the freeze frame. For details, refer to
EC-60, "FREEZE FRAME DATA AND 1ST TRIP
.
MODE 3
DTCs
This mode gains access to emission-related power train trouble codes which were stored
by ECM.
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)
●
Clear freeze frame data (MODE 2)
●
Reset status of system monitoring test (MODE 1)
●
Clear on board monitoring test results (MODE 6 and 7)
MODE 6
(ON BOARD TESTS)
This mode accesses the results of on board diagnostic monitoring tests of specific com-
ponents/systems that are not continuously monitored.
MODE 7
(ON BOARD TESTS)
This mode enables the off board test drive to obtain test results for emission-related
powertrain components/systems that are continuously monitored during normal driving
conditions.
MODE 8
—
This mode is not applicable on this vehicle.
MODE 9
(CALIBRATION ID)
This mode enables the off-board test device to request specific vehicle information such
as Vehicle Identification Number (VIN) and Calibration IDs.

Enter the program according to instruction on the screen or in
the operation manual.

dure.
For further information, see the GST Operation Manual of the
tool maker.
CONSULT-II Reference Value in Data Monitor Mode
EBS00QH6
Remarks:
●
Specification data are reference values.
●
Specification data are output/input values which are detected or supplied by the ECM at the connector.
* Specification data may not be directly related to their components signals/values/operations.
i.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the specification data in
spite of the ignition timing not being adjusted to the specification data. This IGN TIMING monitors the data calculated by the ECM
according to the signals input from the camshaft position sensor and other ignition timing related sensors.

Description

The specification (SP) value indicates the tolerance of the value that is displayed in “DATA MONITOR (SPEC)”
mode of CONSULT-II during normal operation of the Engine Control System. When the value in “DATA MONI-
TOR (SPEC)” mode is within the SP value, the Engine Control System is confirmed OK. When the value in
“DATA MONITOR (SPEC)” mode is NOT within the SP value, the Engine Control System may have one or
more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not light the
MIL.
The SP value will be displayed for the following three items:
●
B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board cor-
rection)
●
A/F ALPHA-B1/B2 (The mean value of air-fuel ratio feedback correction factor per cycle)
●

TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
PFP:00006
Description
EBS00QHC
Intermittent incidents (I/I) may occur. In many cases, the malfunction 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 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
EBS00QHD
1.
INSPECTION START
Erase (1st trip) DTCs. Refer to
EC-68, "HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMA-
.
>> GO TO 2.
2.
CHECK GROUND TERMINALS
Check ground terminals for corroding or loose connection.
Refer to “HOW TO PERFORM EFFICIENT DIAGNOSES FOR AN ELECTRICAL INCIDENT”, GI-21, “Incident
Simulation Tests”.
OK or NG
OK
>> GO TO 3.
NG
>> Repair or replace.

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” or “[1t]”.
III
The symptom described by the customer does not recur.
IV
(1st trip) DTC does not appear during the DTC Confirmation Procedure.
VI
The Diagnostic Procedure for PXXXX does not indicate the malfunctioning area.
