Precautions
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) ªAIR BAGº AND ªSEAT BELT
PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS composition which is available to NISSAN MODEL R20 is as follows (The composition
varies according to the destination and optional equipment.):
IFor a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), front seat
belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
I For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of front
seat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a frontal
collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).
WARNING:
I To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance should be per-
formed by an authorized NISSAN dealer.
I Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
I Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
PRECAUTIONS
IBefore connecting or disconnecting the ECM harness
connector, turn ignition switch OFF and disconnect nega-
tive battery terminal. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned off.
I Do not disassemble ECM.

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 flarenut.
2. Pump the tester handle slowly (once per second) and watch the pressure gauge.
3. Read the pressure gauge when the injection pressure just starts dropping.Initial injection pressure: Used12,259 - 12,749 kPa (122.6 - 127.5 bar,
120 - 130 kg/cm
2, 1,706 - 1,849 psi)
New 12,749 - 13,730 kPa (127.5 - 137.3 bar,
130 - 140 kg/cm
2, 1,849 - 1,991 psi)
Always check initial injection pressure using a new nozzle.
4. To adjust injection pressure, change adjusting shims. (No. 2 - 4 nozzle)
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.

How to Erase DTC (Without CONSULT-II)
1. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least5 seconds and then turn it ªONº (engine stopped) again.
2. Change the diagnostic test mode from Mode II to Mode I by using the data link connector. (See EC-346.)
The emission related diagnostic information in the ECM can be erased by changing the diagnostic test mode.
I If the battery is disconnected, the emission-related diagnostic information will be lost after approx.
24 hours.
I Erasing the emission-related diagnostic information using CONSULT-II is easier and quicker than
switching the diagnostic test mode using the data link connector.
Malfunction Indicator (MI)
1. The malfunction indicator will light up when the ignition switch
is turned ON without the engine running. This is a bulb check.
I If the malfunction indicator does not light up, refer to EL sec-
tion (ªWARNING LAMPS/WIRING DIAGRAMº) or see MI &
DATA LINK CONNECTORS.
2. When the engine is started, the malfunction indicator should go off.
If the lamp remains on, the on board diagnostic system has
detected an engine system malfunction.
If MI illuminates or flashes irregularly after starting engine,
water may have accumulated in fuel filter. Drain water from
fuel filter.
ON BOARD DIAGNOSTIC SYSTEM FUNCTION
The on board diagnostic system has the following three functions.

Test Mode KEY and ENG.
Status Function Explanation of Function

This function checks the MI bulb for damage (blown, open
circuit, etc.).
If the MI does not come on, check MI circuit. (See EC-475.)

WARNING This is a usual driving condition. When ECM detects a
malfunction, the MI will light up to inform the driver that a mal-
function has been detected.

Diagnostic Trouble Code (DTC) (Cont'd)
EC-345
http://vnx.su/

DIAGNOSTIC TEST MODE IÐBULB CHECK
In this mode, the MALFUNCTION INDICATOR on the instrument panel should stay ON. If it remains OFF,
check the bulb. Refer to EL section (ªWARNING LAMPS/WIRING DIAGRAMº) or see EC-475.
DIAGNOSTIC TEST MODE IÐMALFUNCTION WARNING
MICondition
ON When a malfunction is detected or the ECM's CPU is malfunctioning.
OFF No malfunction.
I These Diagnostic Trouble Code Numbers are clarified in Diagnostic Test Mode II (SELF-DIAGNOSTIC
RESULTS).
DIAGNOSTIC TEST MODE IIÐSELF-DIAGNOSTIC RESULTS
In this mode, DTC is indicated by the number of blinks of the MI as shown below.
Long (0.6 second) blinking indicates the two LH digits of number and short (0.3 second) blinking indicates the
two RH digits of number. For example, the MI blinks 10 times for 6 seconds (0.6 sec x 10 times) and then it
blinks three times for about 1 second (0.3 sec x 3 times). This indicates the DTC ª1003º.
In this way, all the detected malfunctions are classified by their DTC numbers. The DTC ª0505º refers to no
malfunction. (See TROUBLE DIAGNOSIS Ð INDEX, EC-313.)
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 repeating consecutively twice. (Refer to
ªHOW TO SWITCH DIAGNOSTIC TEST MODESº on previous page.)
IIf the battery terminal is disconnected, the diagnostic trouble code will be lost from the backup
memory within 24 hours.
I Be careful not to erase the stored memory before starting trouble diagnoses.
I If the MI flashes or ªNATS MALFUNCTIONº is displayed on ªSELF-DIAG RESULTSº screen, perform
self-diagnostic results mode with CONSULT-II using NATS program card (NATS-E940). Refer to EL
section.
I Confirm no self-diagnostic results of NATS is displayed before touching ªERASEº in ªSELF-DIAG
RESULTSº mode with CONSULT-II.
I When replacing ECM, initialisation of NATS system and registration of all NATS ignition key IDs
must be carried out with CONSULT-II using NATS program card (NATS-E940).
Therefore, be sure to receive all keys from vehicle owner.

Overall Function Check
Use this procedure to check the overall function of the cooling fan.
During this check, a DTC might not be confirmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
the radiator.
Wrap a thick cloth around the cap. Carefully remove the cap
by turning it a quarter turn to allow built-up pressure to
escape. Then turn the cap all the way off.
WITH CONSULT-II
1) Check the coolant level in the reservoir tank and radiator.Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-444.
2) Confirm whether customer filled the coolant or not. If customer filled the coolant, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-444.
3) Turn ignition switch ªONº.
4) Perform ªCOOLING FANº in ªACTIVE TESTº mode with CON- SULT-II and make sure that cooling fans operate.
If NG, go to ªDiagnostic Procedureº, EC-444.
WITHOUT CONSULT-II

tic Procedureº, EC-444.
2) Confirm whether customer filled the coolant or not. If customer filled the coolant, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-444.
3) Start engine. Be careful not to overheat engine.
4) Set temperature control lever to full cold position.
5) Turn air conditioner switch ªONº.
