   NO: GO TO  11.

• Check the "Performance Priority" in the "SRT ITEM" table. Refer to "DESCRIPTION ".
• 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.

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).
2. Start the engine.
3. 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 ".

     : GO TO 6.

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.

• 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.

• 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.

• 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.
