SRT Set Driving Pattern Infiniti Q60 I

SRT Set Driving Pattern

CAUTIONAlways drive the vehicle in safe manner according to traffic conditions and obey all traffic laws.

Scheme 151

Scheme 151

*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.

  1. The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving habits, etc.
  2. "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

  1. Sea level
  2. Flat road
  3. Ambient air temperature: 20 - 30°C (68 - 86°F)

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 - 30°C (68 - 86°F)]

  1. CHECK DTC Check DTC. Is any DTC detected? YES: Repair malfunction(s) and erase DTC. Refer to " «DTC INDEX»(ref-659741-S38597195822014100100000) ". 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 " «ON BOARD DIAGNOSIS FUNCTION»(ref-659742-S16852230562014100100000) ". With GST Select Service $01 with GST. Is SRT code(s) set? YES: GO TO 12 . NO-1: With CONSULT: GO TO 3. NO-2: Without CONSULT: GO TO 4 .
  3. DTC CONFIRMATION PROCEDURE Select "SRT WORK SUPPORT" in "DTC & SRT CONFIRMATION" mode with CONSULT. 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 " «DESCRIPTION»(ref-659742-S02898971032014100100000) ". Check DTC. Is any DTC detected? YES: Repair malfunction(s) and erase DTC. Refer to " «DTC INDEX»(ref-659741-S38597195822014100100000) ". NO: GO TO 11 .
  4. PERFORM ROAD TEST Check the "Performance Priority" in the "SRT ITEM" table. Refer to " «DESCRIPTION»(ref-659742-S02898971032014100100000) ". Perform the most efficient SRT set driving pattern to set the SRT properly. Refer to " «SRT SET DRIVING PATTERN»(ref-659742-S41933586722014100100000) ". In order to set all SRTs, the SRT set driving pattern must be performed at least once. : GO TO 5.
  5. PATTERN 1 Check the vehicle condition; Engine coolant temperature is -10 to 35°C (14 to 95°F). Fuel tank temperature is more than 0°C (32°F). Start the engine. Keep engine idling until the engine coolant temperature is greater than 70°C (158°F) NOTE: ECM terminal voltage is follows; Engine coolant temperature -10 to 35°C (14 to 95°F): 3.0 - 4.3 V 70° (158°F): Less than 4.1 V Fuel tank temperature: Less than 1.4 V Refer to " «REFERENCE VALUE»(ref-659741-S29071355252014100100000) ". : GO TO 6.
  6. PATTERN 2 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. 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. 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°C (59 - 95°F). CAUTION: Never turn the ignition switch ON while cooling down the engine. Engine coolant temperature at engine start is between 15 - 35°C (59 - 95°F) and has lowered 45°C (113°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 " «ON BOARD DIAGNOSIS FUNCTION»(ref-659742-S16852230562014100100000) ". 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: Go to " «DESCRIPTION»(ref-659742-S02898971032014100100000) ". NO: END

When a DTC is stored in ECM

When a DTC is stored in ECM and MIL is ON, a permanent DTC is erased with MIL shut-off if the same malfunction is not detected after performing the driving pattern for MIL shut-off three times in a raw.

When a DTC is not stored in ECM

The erasing method depends on a permanent DTC stored in ECM. Refer to the following table.

Note. If the applicable permanent DTC includes multiple groups, perform the procedure of Group B first. If the permanent DTC is not erased, perform the procedure of Group A.
