conditions
• Engine coolant temperature: More than 76° C (169° F)
• Condition of TC-SST: Shift lever "D" range
Test
procedure
1. Start the engine with all the accessories switched OFF.
2. Drive the vehicle for 6 minutes at the following conditions. (During the monitor)
NOTE: When the system is normal, the monitor is completed earlier.
• Vehicle speed: More than 30 km/h (19 mph)
• Engine speed: More than 1,500 r/min, less than 3,500 r/min
• Engine load: More than 20 %, less than 60 %
• Without rapid accelerator pedal movement
3. Stop the vehicle in a safe place and turn the ignition switch to "LOCK" (OFF) position.
4. Start the engine and do Steps 1 to 3 again.
NOTE: When the vehicle is operating normally and the OBD-II Drive Cycle is carried out,
the Readiness Codes will be set as "Complete" on the first drive cycle. The second drive
cycle is required to set the Readiness Codes as "Complete" if a fault is detected during
the first drive cycle.
5. Confirm that the diagnostic trouble code (DTC) is not output.

• Intake air temperature: More than −10° C (14° F)
• Barometric pressure: More than 76 kPa (22.4 in.Hg)
• Condition of TC-SST: Shift lever "D" range
Test
procedure
1. Start the engine with all accessories switched OFF.
2. Drive the vehicle for 5 minutes at the following conditions. (During the monitor)
• Engine speed: Less than 3,500 r/min
• Airflow rate: More than 13 g/sec, less than 45 g/sec
• Accelerator pedal: Except full close
• Without rapid accelerator pedal movement
3. Release the accelerator pedal for 5 seconds.
4. Drive the vehicle for 3 minutes at the following conditions. (During the monitor)
• Engine speed: Less than 3,500 r/min
• Airflow rate: More than 13 g/sec, less than 45 g/sec
• Accelerator pedal: Except full close
• Without rapid accelerator pedal movement
NOTE: When the system is normal, the monitor is completed earlier.
5. Stop the vehicle in a safe place and turn the ignition switch to "LOCK" (OFF) position.
6. Start the engine and do Steps 1 to 5 again.
NOTE: When the vehicle is operating normally and the OBD-II Drive Cycle is carried out,
the Readiness Codes will be set as "Complete" on the first drive cycle. The second drive
cycle is required to set the Readiness Codes as "Complete" if a fault is detected during
the first drive cycle.
