and keep it released for more than 10 seconds. Depress the accelerator pedal until vehicle speed is 90 km/h
(56 MPH) again.

• The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving
habits, etc.
• “Zone A” is the fastest time where required for the diagnosis under normal conditions*. If the diagnosis is not
completed within “Zone A”, the diagnosis can still be performed within “Zone B”.
