OBD port NISSAN ALMERA TINO 2001 Service Repair Manual

The SELF-DIAGNOSIS results will be as follows:
The first SELF-DIAGNOSIS will indicate damage to the vehicle speed sensor or the revolution sensor.
During the next SELF-DIAGNOSIS, performed after checking the sensor, no damages will be indicated.
EURO-OBD SELF-DIAGNOSISNLAT0004S04+CVT self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the SPORT indicator lamp. Refer to the table on AT-22 for the indicator used to dis-
play each self-diagnostic result.
+The self-diagnostic results indicated by the MI are automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure ªHOW TO ERASE DTCº on AT-19 to complete the repair and avoid
unnecessary blinking of the MI.
For details of EURO-OBD, refer to EC section (ªON BOARD DIAGNOSTIC SYSTEM DESCRIPTIONº).
+Certain systems and components, especially those related to EURO-OBD, may use a new style
slide-locking type harness connector.
For description and how to disconnect, refer to EL section, ªDescriptionº, ªHARNESS CONNEC-
TORº.

IntroductionNLAT0017The CVT system has two self-diagnostic systems.
The first is the emission-related on board diagnostic system (EURO-OBD) performed by the TCM in combi-
nation with the ECM. The malfunction is indicated by the MI (malfunction indicator) and is stored as a DTC in
the ECM memory but not the TCM memory.
The second is the TCM original self-diagnosis indicated by the CVT indicator (warning) lamp or SPORT indi-
cator lamp. The malfunction is stored in the TCM memory. The detected items are overlapped with EURO-
OBD self-diagnostic items. For detail, refer to AT-28.
EURO-OBD Function for CVT SystemNLAT0018The ECM provides emission-related on board diagnostic (EURO-OBD) functions for the CVT system. One
function is to receive a signal from the TCM used with EURO-OBD-related parts of the CVT system. The sig-
nal is sent to the ECM when a malfunction occurs in the corresponding EURO-OBD-related part. The other
function is to indicate a diagnostic result by means of the MI (malfunction indicator) on the instrument panel.
Sensors, switches and solenoid valves are used as sensing elements.
The MI automatically illuminates in Two Trip Detection Logic when a malfunction is sensed in relation to CVT
system parts.
EURO-OBD Diagnostic Trouble Code (DTC)NLAT0020HOW TO READ DTC AND 1ST TRIP DTCNLAT0020S01DTC and 1st trip DTC can be read by the following methods.
1.(
No Tools)The number of blinks of the malfunction indicator in the Diagnostic Test Mode II (Self-Di-
agnostic Results) Examples: 0705, 0710, 0715, 0720, etc. For details, refer to EC section [ªMalfunction
Indicator (MI)º, ªON BOARD DIAGNOSTIC SYSTEM DESCRIPTIONº].
These DTCs are controlled by NISSAN.
2.(
with CONSULT-II orGST)CONSULT-II or GST (Generic Scan Tool) Examples: P0705, P0710,
P0720, P0725, etc.
These DTCs are prescribed by ISO15031-6.
(CONSULT-II also displays the malfunctioning component or system.)
+1st trip DTC No. is the same as DTC No.
+Output of the diagnostic trouble code indicates that the indicated circuit has a malfunction.
However, in case of the Mode II and GST they do not indicate whether the malfunction is still
occurring or occurred in the past and returned to normal.
CONSULT-II can identify them as shown below. Therefore, using CONSULT-II (if available) is rec-
ommended.
A sample of CONSULT-II display for DTC is shown at left. DTC or 1st trip DTC of a malfunction is displayed
in SELF-DIAGNOSTIC RESULTS mode for ªENGINEº with CONSULT-II. Time data indicates how many times
the vehicle was driven after the last detection of a DTC.
SAT250K
If the DTC is being detected currently, the time data will be ª0º.

TCM Self-diagnostic Procedure (No Tools)=NLAT0022S0703Preparation
1. Turn ignition switch to ªOFFº position.
2. If throttle opener is equipped, connect the handy type vacuum
pump to the throttle opener and apply vacuum þ25.3 kPa
(þ253 mbar, þ190 mmHg, þ7.48 inHg). (If throttle opener is not
equipped, skip this step.)
3. Disconnect the throttle position switch harness connector.
4. Turn ignition switch to ªONº position.
5. Check continuity between terminals 4 and 5 of the closed
throttle position switch.
Continuity should exist.
(If continuity does not exist, check throttle opener and
closed throttle position switch. Then increase vacuum
until closed throttle position switch shows continuity.)
6. Connect the throttle position switch harness connector.
7. Warm up the engine.
8. Turn the ignition switch from ON to OFF two more times, and
then turn to OFF.
9. In the ªPº position of the selector lever, turn the ignition switch
ON, and verify that the CVT warning lamp turns on for about
2 seconds.
10. Turn the ignition switch OFF.
11. Press the brake pedal, and shift the selector lever to the ªDº
position.
12. Turn the ignition switch ON.
13. Release the brake, and shift the selector lever to the ªLº posi-
tion.
14. Fully depress both brake and accelerator pedals all the way to
the floor. Without releasing the brake and accelerator pedals,
shift the selector lever to the ªDº position.
15. Read the display from the SPORT indicator lamp to complete
the diagnosis.
