IGNITION SIGNAL
Component Inspection (Ignition Coil with Power Transistor)
INFOID:0000000001161980
1.CHECK IGNITION COIL WITH POWER TRANSISTOR-I
1. Turn ignition switch OFF.
2. Disconnect ignition coil harness connector.
3. Check resistance between ignition coil terminals as follows.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace malfunctioning ignition coil with power transistor.
2.CHECK IGNITION COIL WITH POWER TRANSISTOR-II
CAUTION:
Do the following procedure in the place where ventilation is good without the combustible.
1. Turn ignition switch OFF.
2. Reconnect all harness connectors disconnected.
3. Remove fuel pump fuse in IPDM E/R to release fuel pressure.
NOTE:
Do not use CONSULT-III to release fuel pressure, or fuel pressure applies again during the following pro-
cedure.
4. Start engine.
5. After engine stalls, crank it two or three times to release all fuel pressure.
6. Turn ignition switch OFF.
7. Remove all ignition coil harness connectors to avoid the electrical discharge from the ignition coils.
8. Remove ignition coil and spark plug of the cylinder to be checked.
9. Crank engine for 5 seconds or more to remove combustion gas in the cylinder.
10. Connect spark plug and harness connector to ignition coil.
11. Fix ignition coil using a rope etc. with gap of 13 - 17 mm (0.52 -
0.66 in) between the edge of the spark plug and grounded metal
portion as shown in the figure.
12. Crank engine for about three seconds, and check whether spark
is generated between the spark plug and the grounded metal
portion.
CAUTION:
 Do not approach to the spark plug and the ignition coil
within 50 cm (19.7 in). Be careful not to get an electrical
shock while checking, because the electrical discharge
voltage becomes 20kV or more.
 It might cause to damage the ignition coil if the gap of more than 17 mm 0.66 in) is taken.
NOTE:
When the gap is less than 13 mm (0.52 in), the spark might be generated even if the coil is mal-
functioning.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace malfunctioning ignition coil with power transistor.
Component Inspection (Condenser)INFOID:0000000001161981

FUEL PRESSURE
4. Connect fuel hose for fuel pressure check (1) to fuel tube
(engine side) with clamp (2) as shown in the figure.
 No.2 spool (5)
 Wipe off oil or dirt from hose insertion part using cloth moist-
ened with gasoline.
 Apply proper amount of gasoline between top of the fuel tube
(3) and No.1 spool (4).
 Insert fuel hose for fuel pressure check until it touches the
No.1 spool on fuel tube.
 Use NISSAN genuine hose clamp (part number: 16439 N4710
or 16439 40U00).
 When reconnecting fuel line, always use new clamps.
 Use a torque driver to tighten clamps.
 Install hose clamp to the position within 1 - 2 mm (0.04 - 0.08 in).
 Make sure that clamp screw does not contact adjacent parts.
5. Connect fuel tube adapter to quick connector.
 A: Fuel pressure gauge
 B: Fuel hose for fuel pressure check
6. After connecting fuel hose for fuel pressure check, pull the hose
with a force of approximately 98 N (10 kg, 22 lb) to confirm fuel
tube does not come off.
7. Turn ignition switch ON and check for fuel leakage.
8. Start engine and check for fuel leakage.
9. Read the indication of fuel pressure gauge.
 Do not perform fuel pressure check with system operating.
Fuel pressure gauge may indicate false readings.
 During fuel pressure check, confirm for fuel leakage from fuel connection every 3 minutes.
10. If result is unsatisfactory, go to next step.
11. Check the following.
 Fuel hoses and fuel tubes for clogging
 Fuel filter for clogging
 Fuel pump
 Fuel pressure regulator for clogging
If OK, replace fuel pressure regulator.
If NG, repair or replace.Tightening torque: 1 - 1.5 N·m (0.1 - 0.15 kg-m, 9 - 13 in-lb)
At idling:
Approximately 350 kPa (3.5 bar, 3.57 kg/cm

2, 725 psi) during the
phase of the 4 acceleration cycles?
NOTE:
If the rail pressure does not reach the setpoint there is an fuel injector leak that is too great or the pressure sig-
nal is incorrect.
Is the inspection result normal?
YES >> GO TO 11.
NO >> GO TO 8.
8.CHECK RAIL HIGH PRESSURE CONTROL CIRCUIT
Carry out TEST 5.
>> GO TO 11.
9.CHECK ENGINE CONDITION
 Check that the oil level is correct.
 Select “DATA MONITOR” mode with CONSULT-III.
 Check that the “RAIL PRES SET” and “RAIL PRESSURE” indication.
 Does “RAIL PRESSURER” follow “RAIL PRES SET” when the cranking engine.
NOTE:
If the rail pressure does not reach the setpoint there is an fuel injector leak that is too great or the pressure sig-
nal is incorrect.
Is the inspection result normal?
YES >> GO TO 11.
NO >> GO TO 10.
10.CHECK MAJOR LEAK IN FUEL INJECTOR/FUEL INJECTORS OPEN

6.CHECK ENGINE CONDITION
 Check that the oil level is correct and that the engine coolant temperature is normal operation tempera-
ture.60°C (140°F)
 Engine running at idle speed.
- Select “HIGH PRES CIRCUIT LEAK TEST” in “ACTIVE TEST” mode with CONSULT-III.
- Engine will perform 4 acceleration cycles.
- Select “DATA MONITOR” mode with CONSULT-III.
- Check that the “RAIL PRES SET” and “RAIL PRESSURE” indication.
- Does “RAIL PRESSURE” follow “RAIL PRES SET” at during the phase of 4 acceleration cycles?
Is the inspection result normal?
YES >> GO TO 22.
NO >> GO TO 7.
7.CHECK ENGINE COOLANT TEMPERATURE AND FUEL TEMPERATURE
1. Select “DATA MONITOR” mode with CONSULT-III.
2. Check that the “FUEL TEMP” indication when operating at idle speed is between 60 - 80°C (140 - 176°F)
3. Check that the “WATER TEMP” indication is between 80 - 90°C (176 - 194°F)
NOTE:
 When the fuel temperature is above 136°C (277°F), the maximum rail pressure is reduced to protect the
