Nissan Versa (N17): How to set SRT code

Description

OUTLINE

In order to set all SRTs, the selfdiagnoses as in the "SRT ITEM" table must have been performed at least once. Each diagnosis may require actual driving for a long period of time under various conditions.

SRT ITEM

The table below shows required selfdiagnostic items to set the SRT to "CMPLT".

SRT item*1 (CONSULT indication)	Performance Priority*2	Required selfdiagnostic items to set the SRT to "CMPLT"	Corresponding DTC No.
CATALYST	1	Three way catalyst function	P0420
EVAP SYSTEM	1	EVAP control system purge flow monitoring	P0441
	1	EVAP control system	P0445
HO2S	1	Heated oxygen sensor 2	P0137
		Heated oxygen sensor 2	P0138
		Heated oxygen sensor 2	P0139
EGR/VVT SYSTEM	2	Intake value timing control function	P0011

*1: Though displayed on the CONSULT screen, "HO2S HTR" is not SRT item.

*2: If completion of several SRTs is required, perform driving patterns (DTC confirmation procedure), one by one based on the priority for models with CONSULT.

SRT SERVICE PROCEDURE

If a vehicle has failed the state emissions inspection due to one or more SRT items indicating "INCMP", review the flowchart diagnostic sequence, referring to the following flowchart.

SRT Set Driving Pattern

CAUTION: Always drive the vehicle in safe manner according to traffic conditions and obey all traffic laws.

*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.

• The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving habits, etc.
• "Zone A" is the fastest time where required for the diagnosis under normal conditions*. If the diagnosis is not completed within "Zone A", the diagnosis can still be performed within "Zone B".

*: Normal conditions

• Sea level
• Flat road
• Ambient air temperature: 20 - 30C (68 - 86F)

NOTE: Diagnosis is performed as quickly as possible under normal conditions. However, under other conditions, diagnosis may also be performed. [For example: ambient air temperature other than 20 - 30C (68 - 86F)]

Work Procedure

1.CHECK DTC

Check DTC.

Is any DTC detected?

YES >> Repair malfunction(s) and erase DTC. Refer to EC85, "DTC Index".

NO >> GO TO 2.

2.CHECK SRT STATUS

WITH CONSULT

Select "SRT STATUS" in "DTC & SRT CONFIRMATION" mode of "ENGINE" using CONSULT.

WITHOUT CONSULT

Perform "SRT status" mode with EC58, "On Board Diagnosis Function".

WITH GST

Select Service $01 with GST.

Is SRT code(s) set?

YES >> GO TO 11.

NO1 >> With CONSULT: GO TO 3.

NO2 >> Without CONSULT: GO TO 4.

3.DTC CONFIRMATION PROCEDURE

1. Select "SRT WORK SUPPORT" in "DTC & SRT CONFIRMATION" mode with CONSULT.
2. For SRT(s) that is not set, perform the corresponding "DTC CONFIRMATION PROCEDURE" according to the "Performance Priority" in the "SRT ITEM" table.
3. Check DTC.

Is any DTC detected?

YES >> Repair malfunction(s) and erase DTC.

NO >> GO TO 11.

4.PERFORM ROAD TEST

• Check the "Performance Priority" in the "SRT ITEM" table.
• Perform the most efficient SRT set driving pattern to set the SRT properly.
• In order to set all SRTs, the SRT set driving pattern must be performed at least once.

>> GO TO 5.

5.PATTERN 1

1. Check the vehicle condition; Engine coolant temperature is −10 to 35C (14 to 95F). Fuel tank temperature is more than 0C (32F).
2. Start the engine.
3. Keep engine idling until the engine coolant temperature is greater than 70C (158F)

NOTE: ECM terminal voltage is follows;

• Engine coolant temperature −10 to 35C (14 to 95F): 3.0 4.3 V, 70(158F): Less than 1.4 V
• Fuel tank temperature: Less than 4.1 V

>> GO TO 6.

6.PATTERN 2

1. Drive the vehicle. And 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.
2. Depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH) again

NOTE:

• Checking the vehicle speed with GST is advised.
• When steadystate 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.

>> GO TO 7.

7.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).

>> GO TO 8.

8.PATTERN 4

• Operate vehicle following the driving pattern shown in the figure.

• Drive the vehicle in a proper gear at 60 km/h (38 MPH) and maintain the speed.
• Release the accelerator pedal fully at least 5 seconds.
• Repeat the above two steps at least 5 times.

>> GO TO 9.

9.PATTERN 5

• The accelerator pedal must be held very steady during steadystate driving.
• If the accelerator pedal is moved, the test must be conducted again.

>> GO TO 10.

10.PATTERN 6

1. Start the engine and wait at least 2 hours .
2. Turn ignition OFF and wait at least 90 minutes.

>> GO TO 11.

11.CHECK SRT STATUS

WITH CONSULT

Select "SRT STATUS" in "DTC & SRT CONFIRMATION" mode of "ENGINE" using CONSULT.
