REAL TIME DIAGNOSIS IN DATA MONITOR MODE
CONSULT-II has two kinds of triggers and they can be selected by
touching ªSETTINGº in ªDATA MONITORº mode.
1) ªAUTO TRIGº (Automatic trigger):
IThe 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, ªMONITORº
in ªDATA MONITORº screen is changed to ªRecording Data ...
xx%º as shown at left, and the data after the malfunction detec-
tion is recorded. Then when the percentage reached 100%,
ªREAL-TIME DIAGº screen is displayed. If ªSTOPº is touched
on the screen during ª Recording Data ... xx%º, ªREAL-TIME
DIAGº screen is also displayed.
The recording time after the malfunction detection and the
recording speed can be changed by ªTRIGGER POINTº and
ªRecording Speedº. Refer to CONSULT-II OPERATION
MANUAL.
2) ªMANU TRIGº (Manual trigger):
I 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) ªAUTO TRIGº
I While trying to detect the DTC by performing the ªDTC Confir-
mation Procedureº, be sure to select to ªDATA MONITOR
(AUTO TRIG)º mode. You can confirm the malfunction at the
moment it is detected.
I While narrowing down the possible causes, CONSULT-II
should be set in ªDATA MONITOR (AUTO TRIG)º mode, espe-
cially in case the incident is intermittent.
When you are inspecting the circuit by gently shaking (or twist-
ing) the suspicious connectors, components and harness in the
ªDTC Confirmation Procedureº, the moment a malfunction is
found the DTC will be displayed. Refer to GI-22, ªIncident Simu-
lation Testsº.
2) ªMANU TRIGº
I If the malfunction is displayed as soon as ªDATA MONITORº is
selected, reset CONSULT-II to ªMANU TRIGº. By selecting
ªMANU TRIGº 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.

Description for Work Flow
STEPDESCRIPTION
STEP I Get detailed information about the conditions and the environment when the incident/symptom occurred using the
ªDIAGNOSTIC WORKSHEETº as shown on the next page.
STEP II Before confirming the concern, check and write down (print out using CONSULT-II) the Diagnostic Trouble Code
(DTC), then erase the code. (Refer to EC-344). The DTC can be used when duplicating the incident at STEP III &
IV.
Study the relationship between the cause, specified by DTC, and the symptom described by the customer. (The
ªSymptom Matrix Chartº will be useful. Refer to EC-363.)
STEP III Try to confirm the symptom and under what conditions the incident occurs.
The ªDIAGNOSTIC WORK SHEETº is useful to verify the incident. Connect CONSULT-II to the vehicle in DATA
MONITOR (AUTO TRIG) mode and check real time diagnosis results.
If the malfunction code is detected, skip STEP IV and perform STEP V.
STEP IV Try to detect the Diagnostic Trouble Code (DTC) by driving in (or performing) the ªDTC CONFIRMATION PROCE-
DUREº. Check and read the DTC by using CONSULT-II.
During the DTC verification, be sure to connect CONSULT-II to the vehicle in DATA MONITOR (AUTO TRIG) mode
and check real time diagnosis results.
In case the ªDTC CONFIRMATION PROCEDUREº is not available, perform the ªOVERALL FUNCTION CHECKº
instead. The DTC cannot be displayed by this check, however, this simplified ªcheckº is an effective alternative.
The ªNGº result of the ªOVERALL FUNCTION CHECKº is the same as the DTC detection.
STEP V Take the appropriate action based on the results of STEP I through IV.
If the malfunction code is indicated, proceed to TROUBLE DIAGNOSIS FOR DTC.
If the normal code is indicated, proceed to the BASIC INSPECTION. Refer to EC-361. Then perform inspections
according to the Symptom Matrix Chart. Refer to EC-363.
STEP VI Identify where to begin diagnosis based on the relationship study between symptom and possible causes. Inspect
the system for mechanical binding, loose connectors or wiring damage using (tracing) ªHarness Layoutsº.
Gently shake the related connectors, components or wiring harness with CONSULT-II set in ªDATA MONITOR
(AUTO TRIG)º mode.
Check the voltage of the related ECM terminals or monitor the output data from the related sensors with CON-
SULT-II. Refer to EC-369.
The ªDIAGNOSTIC PROCEDUREº in EC section contains a description based on open circuit inspection. A short
circuit inspection is also required for the circuit check in the DIAGNOSTIC PROCEDURE.
Repair or replace the malfunctioning parts.
STEP VII Once you have repaired the circuit or replaced a component, you need to run the engine in the same conditions
and circumstances which resulted in the customer's initial complaint.
Perform the ªDTC CONFIRMATION PROCEDUREº and confirm the normal code (Diagnostic trouble code No. 55)
is detected. If the incident is still detected in the final check, perform STEP VI by using a different method from the
previous one.
Before returning the vehicle to the customer, be sure to erase the unnecessary (already fixed) DTC in ECM. (Refer
to EC-344.)

CHECK INJECTION TIMING.
1. Set No. 1 piston at TDC on its com-pression stroke.
2. Remove injection tubes and air bleeder on the back of injection pump.
3. Set dial gauge so its indicator points to somewhere between 1.0 and 2.0 mm
(0.039 and 0.079 in) on the scale.
4. Turn crankshaft two turns clockwise and check that dial gauge indicates the
same value again.
5. Turn crankshaft counterclockwise about 100 degrees, then turn crankshaft
clockwise slowly, and set dial gauge
indicator to 0 mm at the position it
stops.
6. Turn crankshaft clockwise and set it at TDC using the mark on the crankshaft
pulley.
7. Read plunger lift. Plunger lift:0.36   0.02 mm (0.0142   0.0008

Component Description
FUEL CUT SOLENOID VALVE
When the ignition switch is off, the ECM turns the fuel cut solenoid
valve OFF (under this condition, no current flows through the fuel
cut solenoid valve), shutting off fuel supply.
When the engine is not operating due to trouble, the fuel cut sole-
noid valve may or may not be OFF even when the ignition switch
is ON.

Component Description
CRANKSHAFT POSITION SENSOR (TDC)
The crankshaft position sensor (TDC) monitors engine speed by
means of signals from the sensing plate (with four protrusions)
installed to the clutch housing. The datum signal output is detected
at ATDC 30É and sent to the ECM. The sensor signal is used for
fuel injection control and fuel injection timing control.
