Diagnostic Trouble Codes Confirmation Procedure

WARNING:
  • When performing a road test, select a place where there is no traffic or possibility of a traffic accident and be very careful during testing to avoid occurrence of an accident.
  • Road test should be carried out with 2 persons, a driver and a tester, on a level road.
NOTE: Check to make sure that the following conditions are satisfied when using this "DTC Confirmation Procedure".
  • Intake air temp.: Between -10°C and 70°C (14°F and 158°F)
  • Altitude (barometric pressure): 2500 m, 8202 ft or less (560 mmHg, 75 kPa or more)
  1. Connect scan tool to DLC with ignition switch turned OFF.
  2. Turn ON ignition switch and clear DTC using scan tool.
  3. Increase vehicle speed to 50 - 60 mph, 80-100 km/h. (engine speed: 2500 - 3000 r/min.)
  4. Keep the vehicle speed for 10 min. or more (Throttle valve opening is kept constant in this step).
  5. Stop vehicle and check if DTC / pending DTC exists using scan tool. If not, check if catalyst monitoring test has completed using scan tool. If not in both of the checks (i.e., no DTC / pending DTC and catalyst monitoring test not completed), check vehicle condition (environmental) and repeat step 3 through 5.
