Inspection 
conditions

• Engine coolant temperature at engine start: Less than 36°C (96°F)

• Intake air temperature at engine start: Less than 36°C (96°F)

• Fuel amount at engine start: More than 15%, less than 40%

• Engine coolant temperature: More than 60°C (140°F)

• Intake air temperature: More than 5°C (41°F), less than 45°C (113°F)

• Barometric pressure: More than 76 kPa (22.4 in.Hg)

• Fuel temperature: Less than 36°C (96°F)

• Condition of A/T: Selector lever "D" range

Test 
procedure

1. Start the engine with all the accessories switched OFF.
2. Drive the vehicle for 16 minutes at the following conditions. (During the monitor)

• Engine speed: More than 1,600 r/min, less than 4,000 r/min

• Vehicle speed: More than 20 km/h (12 mph)

• Engine load: More than 20 %, less than 70 %

• Without rapid accelerator pedal movement

NOTE: Keep running as long as possible with the power steering pressure switch in 

the OFF position.

NOTE: When the system is normal, the monitor is completed earlier.

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.
