Description for Work Flow
STEP DESCRIPTION
STEP IGet detailed information about the conditions and the environment when the incident/symptom occurred using the
ªDIAGNOSTIC WORKSHEETº as shown on the next page.
STEP IIBefore confirming the concern, check and write down (print out using CONSULT-II) the Diagnostic Trouble Code
(DTC), then erase the code. (Refer to EC-321). 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-340.)
STEP IIITry 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 IVTry 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 VTake 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-338. Then perform inspections
according to the Symptom Matrix Chart. Refer to EC-340.
STEP VIIdentify 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-346.
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 VIIOnce 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-321.)

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
in) at TDC

with step 5.

Adjusting
1. If plunger lift is not within the specified
value, adjust by turning injection pump.
IIf indication is smaller than the
specified value, turn pump body
away from engine.
IIf indication is larger than the speci-
fied value, turn pump body towards
engine.
2. Tighten injection pump securing bolts
and nuts.

Bolt:
: 32-42N×m

3. Remove dial gauge and install air
bleeder with new washer.
4. Install injection tubes.
Flare nut:
: 20-25N×m
(2.0 - 2.5 kg-m, 14 - 18 ft-lb)

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.
