*1: 1st trip DTC No. is the same as DTC No.
*2: This number is prescribed by SAE J2012.
*3: In Diagnostic Test Mode II (Self-diagnostic results), this number is controlled by NISSAN.
*4: The troubleshooting for this DTC needs CONSULT-III.
*5: When the fail-safe operations for both self-diagnoses occur, the MIL illuminates.
*6: SRT code will not be set if the self-diagnostic result is NG.
*7: When the ECM is in the mode of displaying SRT status, MIL may flash. For the details, refer to “How to Display SRT Status”.
*8: When erasing this DTC, always use CONSULT-III or GST.
How to Set SRT Code
INFOID:0000000004349979
To 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.
WITH CONSULT-III
Perform corresponding DTC CONFIRMATION PROCEDURE one by one based on Performance Priority in
the table on “SRT Item”.

The most efficient driving pattern in which SRT codes can be properly set is explained on the below. The driv-
ing pattern should be performed one or more times to set all SRT codes.
DRIVING PATTERN
• The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving
habits, etc.
Zone A refers to the range where the time, required for the diagnosis under normal conditions*, is the short-
est.
PBIB3622E
EC-1020
< ECU DIAGNOSIS >
[QR25DE EXCEPT FOR CALIFORNIA]
ECM
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:
• 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 terminal 46 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 terminal 46 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 95 and ground is less than 4.1V).
Pattern 2:
• When 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.
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 Position for CVT Models
Set the selector lever in the D position.
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
INFOID:0000000004351812
The following is the information specified in Service $06 of SAE J1979.
The test value is a parameter used to determine whether a system/circuit diagnostic test is OK or NG 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.
These data (test value and test limit) are specified by On Board Monitor ID(OBDMID), Test ID (TID), Unit and
Scaling ID and can be displayed on the GST screen.
