Work Procedure

In order to set all SRTs, the self-diagnoses 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.

The table below shows required self-diagnostic items to set the SRT to "CMPLT".

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

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.

1. CHECK DTC 

   Check DTC.

   Is any DTC detected?

   YES

   Repair malfunction(s) and erase DTC. Refer to DTC Index .

   NO

   GO TO 2.

2. CHECK SRT STATUS 

   WITH CONSULT

   Select "SRT STATUS" in "DTC & SRT CONFIRMATION" mode with CONSULT.

   WITHOUT CONSULT

   Perform "SRT status" mode with Diagnosis Description .

   WITH GST

   Select Service $01 with GST.

   Is SRT code(s) set?

   YES

   GO TO 12.

   NO

   With CONSULT: GO TO 3.

   NO

   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. Refer to Work Procedure .
   3. Check DTC.

   Is any DTC detected?

   YES

   Repair malfunction(s) and erase DTC. Refer to DTC Index .

   NO

   GO TO 11.

4. PERFORM ROAD TEST 
   • Check the "Performance Priority" in the "SRT ITEM" table. Refer to Work Procedure .
   • Perform the most efficient SRT set driving pattern to set the SRT properly. Refer to SRT Set Driving Pattern .

     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 35 deg. C (14 to 95 deg. F).
      • Fuel tank temperature is more than 0 deg. C (32 deg. F).
   2. Start the engine.
   3. Keep engine idling until the engine coolant temperature is greater than 70 deg. C (158 deg. F)
   NOTE: ECM terminal voltage is follows;

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

   Refer to Physical Values .

   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 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.

   GO TO 7.

7. PATTERN 3 
   • Operate vehicle following the driving pattern shown in the figure, below.

   • 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, below.

     Courtesy of NISSAN NORTH AMERICA, INC.

     • 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 steady-state driving.
   • If the accelerator pedal is moved, the test must be conducted again.

   GO TO 10.

10. PATTERN 6 
    • Cool down the engine so that the engine coolant temperature lowers between 15 - 35 deg. C (59 - 95 deg. F).
      CAUTION: Never turn the ignition switch ON while cooling down the engine.
    • Engine coolant temperature at engine start is between 15 - 35 deg. C (59 - 95 deg. F) and has lowered 45 deg. C (113 deg. F) or more since the latest engine stop.

    GO TO 11.

11. CHECK SRT STATUS 

    WITH CONSULT

    Select "SRT STATUS" in "DTC & SRT CONFIRMATION" mode with CONSULT.

    WITHOUT CONSULT

    Perform "SRT status" mode with Diagnosis Description .

    WITH GST

    Select Service $01 with GST.

    Is SRT(s) set?

    YES

    GO TO 12.

    NO

    Call TECH LINE or take appropriate action.

12. CHECK PERMANENT DTC 
    NOTE: Permanent DTC cannot be checked with a tool other than CONSULT or GST.

    With CONSULT

    Select "SRT STATUS" in "DTC & SRT CONFIRMATION" mode with CONSULT.

    With GST

    Select Service $0A with GST.

    Is permanent DTC(s) detected?

    YES

    Refer to Work Procedure .

    NO
