ON BOARD DIAGNOSTIC (OBD) SYSTEM
• Sea level
• Flat road
• Ambient air temperature: 20 - 30 °C (68 - 86 °F)
• Diagnosis is performed as quickly as possible under normal conditions.
Under different conditions [For example: ambient air temperature other than 20 - 30 °C (68 - 86 °F)], diagno-
sis may also be performed.
Pattern 1:
• The engine is started at the engine coolant temperature of −10 to 35 °C (14 to 95 °F)
(where the voltage between the ECM te rminal 38 and ground is 3.0 - 4.3V).
• The engine must be operated at idle speed until the engine coolant temperature is greater than 70°C
(158 °F) (where the voltage between the ECM te rminal 38 and ground is lower than 1.4V).
• The engine is started at the fuel tank temperature of warmer than 0 °C (32 °F) (where the voltage
between the ECM terminal 43 and ground is less than 4.1V).
Pattern 2:
• When steady-state driving is performed again even afte r it is interrupted, each diagnosis can be conducted.
In this case, the time required for diagnosis may be extended.
Pattern 3:
• Operate vehicle following the driving pattern shown in the figure.
• Release the accelerator pedal during decelerating vehicle speed
from 90 km/h (56 MPH) to 0 km/h (0 MPH).
Pattern 4:
• The accelerator pedal must be held very steady during steady-
state driving.
• If the accelerator pedal is moved, the test must be conducted all
over again.
*1: Depress the accelerator pedal until vehicle speed is 90 km/h (56
MPH), then release the accelerator pedal and keep it released for
more than 10 seconds. Depress the accelerator pedal until vehicle
speed is 90 km/h (56 MPH) again.
*2: Checking the vehicle speed with GST is advised.
Suggested Transmission Gear Po sition for A/T and CVT Models
Set the selector lever in the D position (CVT), D position with the overdrive switch turned ON (A/T).
Suggested upshift speeds for M/T models
Shown below are suggested vehicle speeds for shifting into a higher gear. These suggestions relate to fuel
economy and vehicle performance. Actual upshift speeds will vary according to road conditions, the weather
and individual driving habits.
Suggested Maximum Speed in Each Gear
Downshift to a lower gear if the engine is not running smoothly, or if you need to accelerate.
Do not exceed the maximum suggested speed (shown below) in any gear. For level road driving, use the high-
est gear suggested for that speed. Always observe post ed speed limits and drive according to the road condi-
tions to ensure safe operation. Do not over-rev the engine when shifting to a lower gear as it may cause
engine damage or loss of vehicle control. PBIB2244E

ON BOARD DIAGNOSTIC (OBD) SYSTEM
tified codes can be identified by using the CONSULT-II I or GST. A DTC will be used as an example for how to
read a code.
A particular trouble code can be identified by the number of four-digit numeral flashes. The “zero” is indicated
by the number of ten flashes. The “A” is indicated by the number of eleven flash. The length of time the
1,000th-digit numeral flashes on and off is 1.2 seconds consisting of an ON (0.6-second) - OFF (0.6-second)
cycle. The 100th-digit numeral and lower digit numer als consist of a 0.3-second ON and 0.3-second OFF
cycle. A change from one digit numeral to another occurs at an interval of 1.0-second OFF. In other words, the
later numeral appears on the display 1.3 seconds after the former numeral has disappeared.
A change from one trouble code to another occu rs at an interval of 1.8-second OFF.
In this way, all the detected malfunctions are classi fied by their DTC numbers. The DTC 0000 refers to no mal-
function. (See EC-1015 )
How to Erase Diagnostic Test Mode II (Self-diagnostic Results)
The DTC can be erased from the back-up memory in the ECM by depressing accelerator pedal.
Refer to "How to Erase Diagnostic Test Mode II (Self-diagnostic Results)".
• If the battery is disconnected, the DTC will be lost from the backup memory within 24 hours.
• Be careful not to erase the stored memo ry before starting trouble diagnoses.

RELATIONSHIP BETWEEN MIL, 1ST TRIP DTC, DTC, AND DETECTABLE ITEMS
• When a malfunction is detected for the first time, the 1st trip DTC and the 1st trip freeze frame data are
stored in the ECM memory.
• When the same malfunction is detected in two consec utive trips, the DTC and the freeze frame data are
stored in the ECM memory, and the MIL will come on. For details, refer to EC-1051, " Two Trip Detection
Logic " .
• The MIL will go off after the vehicle is driven 3 time s (driving pattern B) with no malfunction. The drive is
counted only when the recorded driving pattern is met (as stored in the ECM). If another malfunction occurs
while counting, the counter will reset.
• The DTC and the freeze frame data will be stored until the vehicle is driven 40 times (driving pattern A) with-
out the same malfunction recurring (except for Misfire and Fuel Injection System). For Misfire and Fuel Injec-
tion System, the DTC and freez e frame data will be stored until the vehicle is driven 80 times (driving pattern PBIB3005E

Driving pattern B means the vehicle operation as follows: *1: When the same malfunction is de-
tected in two consecutive trips, MIL
will light up. *2: MIL will go off after vehicle is driven 3
times (pattern B) without any mal-
functions. *3: When the same malfunction is de-
tected in two consecutive trips, the
DTC and the freeze frame data will be
stored in ECM.
*4: The DTC and the freeze frame data will not be displayed any longer after
vehicle is driven 80 times (pattern C)
without the same malfunction. (The
DTC and the freeze frame data still
remain in ECM.) *5: When a malfunction is detected for
the first time, the 1st trip DTC and the
1st trip freeze frame data will be
stored in ECM. *6: The 1st trip DTC and the 1st trip
freeze frame data will be cleared at
the moment OK is detected.
*7: When the same malfunction is de- tected in the 2nd trip, the 1st trip
freeze frame data will be cleared. *8: 1st trip DTC will
be cleared when ve-
hicle is driven once (pattern C) with-
out the same malfunction after DTC
is stored in ECM. SEF392S

BASIC SERVICE PROCEDURE
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications. Refer to EC-1078, " Basic Inspection " .
13. If idle speed and ignition timing are not within the specification, Idle Air Volume Learning will not be carried out successfully. In this case, find the cause of the incident by referring to the DIAGNOSTIC PROCE-
DURE below.
DIAGNOSTIC PROCEDURE
If idle air volume learning cannot be performed successfully, proceed as follows:
1. Check that throttle valve is fully closed.
2. Check PCV valve operation.
3. Check that downstream of throttl e valve is free from air leakage.
4. When the above three items check out OK, engine component parts and their installation condi-
tion are questionable. Check and elim inate the cause of the incident.
It is useful to perform EC-1130 .
5. If any of the following conditio ns occur after the engine has st arted, eliminate the cause of the
incident and perform Idle Air Vo lume Learning all over again:
- Engine stalls.
- Erroneous idle.

1. Remove fuel pump fuse (1) located in IPDM E/R (2).
• : Vehicle front
2. Start engine.
3. After engine stalls, crank it two or three times to release all fuel pressure.
4. Turn ignition switch OFF.
5. Reinstall fuel pump fuse after servicing fuel system.
FUEL PRESSURE CHECK CAUTION:
Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
NOTE:
• Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel
pressure cannot be completely released because C11 models do not have fuel return system.
• The fuel hose connection method u sed when taking fuel pressure check must not be used for other
purposes.
• Be careful not to scratch or put debris around connection area when servicing, so that the quick
connector maintains seal abil ity with O-rings inside.
• Do not perform fuel pressure check with electrical syst ems operating (i.e. lights, rear defogger, A/C,
etc.) Fuel pressure gauge may indicate false readin gs due to varying engine load and changes in
manifold vacuum.
1. Release fuel pressure to zero. Refer to "FUEL PRESSURE RELEASE".
2. Prepare fuel hose for fuel pressure check B and fuel tube adapter (KV10118400) D, then connect fuel pressure gauge A.
• : To quick connector
• : To fuel tube (engine side)
• C: Clamp
• Use suitable fuel hose for fuel pressure check (genuine
NISSAN fuel hose without quick connector).
• To avoid unnecessary force or tension to hose, use moder- ately long fuel hose for fuel pressure check.
• Do not use the fuel hose for checking fuel pressure with dam- age or cracks on it.
• Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose. Refer to EM-156, " Removal and Installation " .
• Do not twist or kink fuel hose because it is plastic hose.
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 positi on within 1 - 2 mm (0.04 - 0.08 in).
• Make sure that clamp screw does not contact adjacent parts. PBIB2958E
