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 [C].
- Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
- Check if any DTCs (pending DTCs) are set.
HINT:
If the monitor does not change to Complete, and no pending DTCs are stored, perform the following procedure.

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 [E].
- Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
- Check if any DTCs (pending DTCs) are stored.
HINT:
If monitor item does not change to Complete, and no pending DTCs are stored, extend the driving time.
