Brake Booster
ON-VEHICLE SERVICE
Operating check
+Depress brake pedal several times with engine off. After
exhausting vacuum, make sure there is no change in pedal
stroke.
+ Depress brake pedal, then start engine. If pedal goes down
slightly, operation is normal.
Airtight check
+Start engine, and stop it after one or two minutes. Depress
brake pedal several times slowly. Booster is airtight if pedal
stroke is less each time.
+ Depress brake pedal while engine is running, and stop engine
with pedal depressed. The pedal stroke should not change after
holding pedal down for 30 seconds.
REMOVAL
CAUTION:
+Be careful not to splash brake ¯uid on painted areas; it
may cause paint damage. If brake ¯uid is splashed on
painted areas, wash it away with water immediately.
+ Be careful not to deform or bend brake pipes, during
removal of booster.
INSPECTION
Output rod length check
1. Apply vacuum of þ66.7 kPa (þ500 mmHg, þ19.69 inHg) to
brake booster with a hand vacuum pump.
2. Check output rod length. Speci®ed length:10.275 - 10.525 mm (0.4045 - 0.4144 in)
INSTALLATION
CAUTION:
+Be careful not to deform or bend brake pipes during instal-
lation of booster.
+ Replace clevis pin if damaged.
+ Re®ll with new brake ¯uid ``DOT 3''.
+ Never reuse drained brake ¯uid.
+ Take care not to damage brake booster mounting bolt
thread when installing. Due to the narrow angle of

Test and Adjustment
WARNING:
When using nozzle tester, be careful not to allow diesel fuel
sprayed from nozzle to contact your hands or body, and make
sure your eyes are properly protected with goggles.
INJECTION PRESSURE TEST
1. Install nozzle to injection nozzle tester and bleed air from ¯are
nut.
2. Pump the tester handle slowly (one time per second) and watch
the pressure gauge.
3. Read the pressure gauge when the injection pressure just
starts dropping.
Initial injection pressure:
Used
14,220 kPa (142.2 bar, 145 kg/cm
2, 2,062 psi)
New
14,711 - 15,495 kPa (147.1 - 155.0 bar,
150 - 158 kg/cm
2, 2,133 - 2,247 psi)
Always check initial injection pressure using a new nozzle.
4. To adjust injection pressure, change adjusting shims (No. 2 - 4
nozzles).
a. Increasing the thickness of adjusting shims increases ini-
tial injection pressure. Decreasing thickness reduces ini-
tial pressure.
b. A shim thickness of 0.04 mm (0.0016 in) corresponds
approximately to a difference of 471 kPa (4.71 bar, 4.8
kg/cm
2, 68 psi) in initial injection pressure.
Refer to SDS for adjusting shim (EC-189).
LEAKAGE TEST
1. Maintain the pressure at about 981 to 1,961 kPa (9.8 to 19.6
bar, 10 to 20 kg/cm2, 142 to 284 psi) below initial injection
pressure.
2. Check that there is no dripping from the nozzle tip or around the
body.

DTC and MIL Detection Logic
When a malfunction is detected for the ®rst time, the malfunction (DTC) is stored in the ECM memory.
The MIL will light up each time the ECM detects malfunction. However, if the same malfunction is experienced
in two consecutive driving patterns and the engine is still running, the MIL will stay lit up. For diagnostic items
causing the MIL to light up, refer to ``DIAGNOSTIC TROUBLE CODE INDEX'', EC-1.
Diagnostic Trouble Code (DTC)
HOW TO READ DTC
The diagnostic trouble code can be read by the following methods.
1. The number of blinks of the malfunction indicator lamp in the Diagnostic Test Mode II (Self-Diagnostic
Results) Examples: 11, 13, 14, etc.
These DTCs are controlled by NISSAN.
2. CONSULT Examples: ``CAM POS SEN (PUMP)'', etc.
+Output of the trouble code means that the indicated circuit has a malfunction. However, in the Mode
II it does not indicate whether the malfunction is still occurring or occurred in the past and returned
to normal.
CONSULT can identify them. Therefore, using CONSULT (if available) is recommended.
HOW TO ERASE DTC
The diagnostic trouble code can be erased by the following methods.
Selecting ``ERASE'' in the ``SELF-DIAG RESULTS'' mode with CONSULT.
Changing the diagnostic test mode from Diagnostic Test Mode II to Mode I. (Refer to EC-32.)
+If the battery terminal is disconnected, the diagnostic trouble code will be lost within 24 hours.
+When you erase the DTC, using CONSULT is easier and quicker than switching the diagnostic test
modes.
HOW TO ERASE DTC (With CONSULT)
1. If the ignition switch stays ``ON'' after repair work, be sure to turn ignition switch ``OFF'' once. Wait at least
5 seconds and then turn it ``ON'' (Engine stopped) again.
2. Turn CONSULT ``ON'' and touch ``ENGINE''.
3. Touch ``SELF-DIAG RESULTS''.
4. Touch ``ERASE''. (The DTC in the ECM will be erased.)
HOW TO ERASE DTC (No Tools)
1. If the ignition switch stays ``ON'' after repair work, be sure to turn ignition switch ``OFF'' once. Wait at least
5 seconds and then turn it ``ON'' again.
2. Change the diagnostic test mode from Mode II to Mode I. (Refer to EC-32.)

DIAGNOSTIC TEST MODE IÐBULB CHECK
In this mode, the MALFUNCTION INDICATOR LAMP on the instrument panel should stay ON. If it remains
OFF, check the bulb. Refer to EL section (``WARNING LAMPS AND CHIME'') or see EC-188.
DIAGNOSTIC TEST MODE IÐMALFUNCTION WARNING
MALFUNCTION
INDICATOR LAMPCondition
ONWhen the malfunction is detected or the ECM's CPU is malfunctioning. (Refer to ``MIL Illumination'' of the
``DIAGNOSTIC TROUBLE CODE INDEX'', EC-1.)
OFF No malfunction.
+These Diagnostic Trouble Code Numbers are clari®ed in Diagnostic Test Mode II (SELF-DIAGNOSTIC
RESULTS).
DIAGNOSTIC TEST MODE IIÐSELF-DIAGNOSTIC RESULTS
In this mode, a diagnostic trouble code is indicated by the number of blinks of the MALFUNCTION INDICA-
TOR LAMP as shown below.
Long (0.6 second) blinking indicates the number of ten digits, and short (0.3 second) blinking indicates the
number of single digits. For example, the malfunction indicator lamp blinks 4 times for 5 seconds (0.6 sec x
4 times) and then it blinks three times for about 1 second (0.3 sec x 3 times). This indicates the DTC ``43''
and refers to the malfunction of the accelerator position sensor circuit.
In this way, all the detected malfunctions are classi®ed by their diagnostic trouble code numbers. The DTC
``55'' refers to no malfunction. (See DIAGNOSTIC TROUBLE CODE INDEX, EC-1.)
HOW TO ERASE DIAGNOSTIC TEST MODE II (Self-diagnostic results)
The diagnostic trouble code can be erased from the backup memory in the ECM when the diagnostic test mode
is changed from Diagnostic Test Mode II to Diagnostic Test Mode I. (Refer to ``HOW TO SWITCH DIAGNOS-
TIC TEST MODES'' on previous page.)
+If the battery terminal is disconnected, the diagnostic trouble code will be lost from the backup
memory within 24 hours.
+Be careful not to erase the stored memory before starting trouble diagnoses.
+If the MIL blinks or ``NATS MALFUNCTION'' is displayed on
``SELF-DIAG RESULTS'' screen, perform self-diagnostic
results mode with CONSULT using NATS program card
(NATS-E940). Refer to EL section.
+Con®rm no self-diagnostic results of NATS is displayed
before touching ``ERASE'' in ``SELF-DIAG RESULTS'' mode
with CONSULT.
+When replacing ECM, initialisation of NATS V2.0 system
and registration of all NATS V2.0 ignition key IDs must be
carried out with CONSULT using NATS program card
(NATS-E940).
Therefore, be sure to receive all keys from vehicle owner.
Regarding the procedures of NATS initialisation and NATS
ignition key ID registration, refer to CONSULT operation
manual, NATS V2.0.

Injection Timing Control Valve
The injection timing control valve is built into the electronic fuel
injection pump. It controls the timer piston to change the fuel injec-
tion timing.
The timing control valve is a solenoid valve located in the line
between high-pressure chamber and low-pressure chamber. It
changes fuel pressure in the high-pressure chamber.
When current ¯ows through the solenoid (the solenoid turns ON),
the timing control valve opens, advancing fuel injection timing.
When current does not ¯ow through it, the timing control valve
closes, retarding injection timing.
The ECM emits an ON-OFF duty signal. The longer the OFF-
duration, the greater the advance angle. The longer the
ON-duration, the greater the retard angle. This means that chang-
ing the ON-OFF duty ratio makes it possible to achieve an optimal
advance angle and accurately control fuel injection timing.
