Confirmation Driving Pattern
HINT:
- It is necessary for the response of the air fuel ratio sensor (sensor 2) to be normal in order to confirm DTC P0420-00. Therefore, perform the confirmation driving pattern for the air fuel ratio sensor (sensor 2) monitor before performing the confirmation driving pattern for the catalyst efficiency monitor.
- Performing this confirmation driving pattern will activate the catalyst efficiency monitor. This is very useful for verifying the completion of a repair.
- After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
Refer to DTC CHECK / CLEAR [08/2021 - 09/2022] , or refer to DTC CHECK / CLEAR [09/2022 - ]
- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Refer to DTC CHECK / CLEAR [08/2021 - 09/2022] , or refer to DTC CHECK / CLEAR [09/2022 - ]
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the power switch off and wait for at least 30 seconds.
- Turn the power switch on (IG).
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Monitor / Current Monitor.
- Check that Catalyst Efficiency / Current is Incomplete.
- Put the engine in Inspection Mode (Maintenance Mode).
- Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher with the shift lever in P [A].
HINT:
In order to keep the idle stable, turn the A/C and all other electric loads off and do not perform any shift operations.
- With the engine running, drive the vehicle at approximately 75 km/h (47 mph) for 10 minutes or more [B].WARNING:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
- Drive the vehicle while keeping the engine load as constant as possible.
- If the engine stops, further depress the accelerator pedal to restart the engine.
- With the shift lever in S and the engine running, drive the vehicle at 75 km/h (47 mph), and then decelerate the vehicle by releasing the accelerator pedal for 5 seconds or more to perform the fuel-cut [C].WARNING:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
If the engine stops, further depress the accelerator pedal to restart the engine.
- Enter the following menus: Powertrain / Engine / Monitor / Current Monitor / O2 Sensor / Details / SLOW RESPONSE B1S2 [D].
- Check the Test Value for SLOW RESPONSE B1S2.
HINT:
- If Test Value displays a value larger than 0, perform the following procedure, as the O2 Sensor monitor is finished.
- If Test Value displays 0, perform step [C] until it displays a value larger than 0, as the O2 Sensor monitor is not finished.
- Turn the power switch off and wait for at least 30 seconds [F].
- Turn the power switch on (IG).
- Turn the Techstream on.
- Put the engine in Inspection Mode (Maintenance Mode).
- Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher [G].
- With the engine running, drive the vehicle at approximately 75 km/h (47 mph) for 10 minutes or more [H].WARNING:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
- Drive the vehicle while keeping the engine load as constant as possible.
- The monitor item will change to Complete as the Catalyst Efficiency monitor operates.
- If the engine stops, further depress the accelerator pedal to restart the engine.
- Enter the following menus: Powertrain / Engine / Trouble Codes [I].
- Check if any DTCs are stored.
HINT:
- If the monitor item does not change to Complete, and no DTCs are stored, perform the following procedure.
- [A] to [I]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- When clearing the permanent DTCs, do not disconnect the cable from the auxiliary battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.
- With the engine running, drive the vehicle at approximately 100 km/h (62 mph) for 10 minutes or more [J].WARNING:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
- Drive the vehicle while keeping the engine load as constant as possible.
- The monitor item will change to Complete as the Catalyst Efficiency monitor operates.
- If the engine stops, further depress the accelerator pedal to restart the engine.
- Enter the following menus: Powertrain / Engine / Trouble Codes [K].
- Check if any DTCs are stored.
HINT:
If the monitor item does not change to Complete, and no DTCs are stored, extend the driving time.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P0420-00.
- Check the DTC judgment result.
Techstream Display Description NORMAL - DTC judgment completed
- System normal
ABNORMAL - DTC judgment completed
- System abnormal
INCOMPLETE - DTC judgment not completed
- Perform driving pattern after confirming DTC enabling conditions
HINT:
- If the judgment result is NORMAL, the system is normal.
- If the judgment result is ABNORMAL, the system has a malfunction.
- [A] to [K]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- When clearing the permanent DTCs, do not disconnect the cable from the auxiliary battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.
