ECM
*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 that displays SRT status, MIL may flash. For the details, refer to “How to Display SRT Status”.
How to Set SRT Code
INFOID:0000000004362396
To set all SRT codes, self-diagnoses 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”.
WITHOUT CONSULT-III
The most efficient driving pattern in which SRT codes can be properly set is explained below. The driving pat-
tern 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.
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:
PBIB3622E
EC-1560
< ECU DIAGNOSIS >
[VQ35DE]
ECM
• 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 - 4.3 V).
• 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 1.4 V).
• 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 4.1 V).
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 deceleration of 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
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.
Test Value and Test Limit
INFOID:0000000004362397
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.
The items of the test value and test limit will be displayed with GST screen which items are provided by the
ECM. (eg., if bank 2 is not applied on this vehicle, only the items of bank 1 are displayed)
