Confirmation Driving Pattern

HINT:

It is necessary that the response of the heated oxygen sensor is normal in order to confirm DTC P0420. Therefore, perform the driving pattern for the heated oxygen sensor monitor before performing the drive 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.

Connect the Techstream to the DLC3.
Turn the ignition switch to ON.
Turn the Techstream on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON and turn the Techstream on.
Enter the following menus: Powertrain / Engine and ECT / Monitor / Current Monitor.
Check that Catalyst Efficiency / Current is Incomplete.
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 or N (neutral) [A].
HINT:

In order to keep the idling stable, turn off the A/C and all other electric loads and do not perform any shift operations.
Drive the vehicle at approximately 60 km/h (37 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.
With the shift lever in M, S or 2nd gear, drive the vehicle at 60 km/h (37 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.
Enter the following menus: Powertrain / Engine and ECT / Monitor / Current Monitor / O2 Sensor / RL F/C B1S2 [D].
Check the Test Value for RL F/C B1S2.
(a) If Test Value displays a value larger than 0, perform the following procedure, as the O2 sensor monitor is finished.

HINT:

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 ignition switch off and wait for at least 30 seconds [F].
Turn the ignition switch to ON and turn the Techstream on.
Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher [G].
Drive the vehicle at approximately 60 km/h (37 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.
Enter the following menus: Powertrain / Engine and ECT / 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.
Drive the vehicle at a speed between 75 and 100 km/h (47 and 63 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.
Enter the following menus: Powertrain / Engine and ECT / 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.
If no DTC is output, perform a universal trip and check for permanent DTCs.
Refer to DTC CHECK / CLEAR [08/2013 - ]

HINT:
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.

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
N/A	Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

HINT:

If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
