NISSAN PRIMERA 1999 Electronic Repair Manual

Together with the DTC, the SRT code is cleared from the ECM memory using the method described later
(Refer to EC-SR-56). In addition, after engine control components/system are repaired or if the battery termi-
nals remain disconnected for more than 24 hours, all SRT codes may be cleared from the ECM memory.
How to Display SRT CodeNCEC0031S03011.With CONSULT-II
Selecting ªSRT STATUSº in ªDTC CONFIRMATIONº mode with CONSULT-II.
For items whose SRT codes are set, a ªCMPLTº is displayed on the CONSULT-II screen; for items whose
SRT codes are not set, ªINCMPº is displayed as shown below.

How to Set SRT CodeNCEC0031S0302To set all SRT codes, self-diagnosis for the items indicated above must be performed one or more times. Each
diagnosis may require a long period of actual driving under various conditions. The most efficient driving pat-
tern in which SRT codes can be properly set is explained on the next page. The driving pattern should be
performed one or more times to set all SRT codes.

IThe time required for each diagnosis varies with road surface conditions, weather, altitude, individual driv-
ing habits, etc.
Zone A refers to the range where the time required, for the diagnosis under normal conditions*, is the
shortest. Zone B refers to the range where the diagnosis can still be performed if the diagnosis is not
completed within zone A.
*: Normal conditions refer to the following:
þ Sea level
þ Flat road
þ Ambient air temperature: 20 - 30ÉC (68 - 86ÉF)
þ Diagnosis is performed as quickly as possible under normal conditions.
Under different conditions [For example: ambient air temperature other than 20 - 30ÉC (68 - 86ÉF)], diagnosis may
also be performed.
Pattern 1:
IThe engine is started at the engine coolant temperature of þ10 to 35ÉC (14 to 95ÉF) (where the volt-
age between the ECM terminals 70 and 58 is 3.0 - 4.3V).
IThe engine must be operated at idle speed until the engine coolant temperature is greater than 70ÉC
(158ÉF) (where the voltage between the ECM terminals 70 and 58 is lower than 1.4V).
Pattern 2:
IWhen steady-state driving is performed again even after it is interrupted, each diagnosis can be conducted.
In this case, the time required for diagnosis may be extended.
*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 CONSULT-II or GST is advised.
Suggested transmission gear position for CVT models
Set the selector lever in the ªDº position with ªSPORTS MODE SWº ªOFFº or without ªMANUAL MODEº.
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.

TEST VALUE AND TEST LIMIT (GST ONLY Ð NOT APPLICABLE TO CONSULT-II)NCEC0031S04The following is the information specified in Mode 6 of ISO 15031-5.
The test value is a parameter used to determine whether a system/circuit diagnostic test is ªOKº or ªNGº while
being monitored by the ECM during self-diagnosis. The test limit is a reference value which is specified as the
maximum or minimum value and is compared with the test value being monitored.
Items for which these data (test value and test limit) are displayed are the same as SRT code items (6 test
items).
These data (test value and test limit) are specified by Test ID (TID) and Component ID (CID) and can be dis-
played on the GST screen.

HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATIONNCEC0031S06How to Erase DTC (With CONSULT-II)NCEC0031S0601NOTE:
If the diagnostic trouble code is not for CVT related items (see EC-SR-6), skip steps 2 through 4.
1. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
9 seconds and then turn it ªONº (engine stopped) again.
2. Turn CONSULT-II ªONº and touch ªA/Tº.
3. Touch ªSELF-DIAG RESULTSº.
4. Touch ªERASEº. [The DTC in the TCM (Transmission control module) will be erased.] Then touch ªBACKº
twice.
5. Touch ªENGINEº.
6. Touch ªSELF-DIAG RESULTSº.
7. Touch ªERASEº. (The DTC in the ECM will be erased.)
IIf DTCs are displayed for both ECM and TCM (Transmission control module), they need to be erased
individually from the ECM and TCM (Transmission control module).

How to Erase DTC (No Tools)NCEC0031S0603NOTE:
If the diagnostic trouble code is not for CVT related items (see EC-SR-6), skip step 2.
1. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
9 seconds and then turn it ªONº again.
2. Perform ªSELF-DIAGNOSTIC PROCEDURE (Without CONSULT-II)º in AT section titled ªTROUBLE
DIAGNOSISº, ªSelf-diagnosisº. (The engine warm-up step can be skipped when performing the diagnosis
only to erase the DTC.)
3. Change the diagnostic test mode from Mode II to Mode I by using the data link connector. (See EC-SR-
61.)
The emission-related diagnostic information can be erased by changing the diagnostic test mode from Diag-
nostic Test Mode II to Mode I by using the data link connector. (Refer to EC-SR-61.)
NOTE:
IIf the battery is disconnected, the emission-related diagnostic information will be lost after approx.
24 hours.
IErasing the emission-related diagnostic information using CONSULT-II or GST is easier and
quicker than switching the mode using the data link connector.
IThe following data are cleared when the ECM memory is erased.
1) Diagnostic trouble codes
2) 1st trip diagnostic trouble codes
3) Freeze frame data
4) 1st trip freeze frame data
5) System readiness test (SRT) codes
6) Test values
7) Distance traveled while MI is activated
8) Others
Actual work procedures are explained using a DTC as an example. Be careful so that not only the DTC, but
all of the data listed above, are cleared from the ECM memory during work procedures.
Malfunction Indicator (MI)
NATS (NISSAN ANTI-THEFT SYSTEM)
IIf the security indicator lights up with the ignition switch in the ªONº position or ªNATS MALFUNC-
TIONº is displayed on ªSELF-DIAG RESULTSº screen, perform self-diagnostic results mode with
CONSULT-II using NATS program card. Refer to NATS (Nissan Anti-Theft System) in EL section.
IConfirm no self-diagnostic results of NATS is displayed before touching ªERASEº in ªSELF-DIAG
RESULTSº mode with CONSULT-II.
IWhen replacing ECM, initialization of NATS system and registration of all NATS ignition key IDs
must be carried out with CONSULT-II using NATS program card.
Therefore, be sure to receive all keys from vehicle owner. Regarding the procedure of NATS initil-
ialization and NATS ignition key ID registration, refer to CONSULT-II operation manual, NATS.

DESCRIPTIONNCEC0032
The MI is located on the instrument panel.
1. The MI will light up when the ignition switch is turned ON without the engine running. This is a bulb check.
IIf the MI does not light up, refer to EL section (ªWARNING LAMPSº) or see EC-SR-329.
2. When the engine is started, the MI should go off.
If the MI remains on, the on board diagnostic system has detected an engine system malfunction.
On Board Diagnostic System FunctionNCEC0032S01The on board diagnostic system has the following four functions.
Diagnostic Test Mode I
1. BULB CHECK:
This function checks the MI bulb for damage (blown, open circuit, etc.).
If the MI does not come on, check MI circuit and ECM test mode selector. (See the following page.)
2. MALFUNCTION WARNING:
This is a usual driving condition. When a malfunction is detected twice in two consecutive driving cycles
(two trip detection logic), the MI will light up to inform the driver that a malfunction has been detected.
The following malfunctions will light up or blink the MI in the 1st trip.
IªMisfire (Possible three way catalyst damage)º
IªClosed loop controlº
IFail-safe mode
Diagnostic Test Mode II
3. SELF-DIAGNOSTIC RESULTS:
This function allows DTCs and 1st trip DTCs to be read.
4. HEATED OXYGEN SENSOR 1 (FRONT) MONITOR:
This function allows the fuel mixture condition (lean or rich), monitored by heated oxygen sensor 1 (front),
to be read.
MI Flashing without DTC
NCEC0032S0101If the ECM is in Diagnostic Test Mode II, MI may flash when engine is running. In this case, check ECM test
mode following ªHOW TO SWITCH DIAGNOSTIC TEST MODESº.
How to switch the diagnostic test (function) modes, and details of the above functions are described later.
