• The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving habits, etc.

  Zone A refers to the range where the time, required for the diagnosis under normal conditions*, is the shortest.

  Zone B refers to the range where the diagnosis can still be performed if the diagnosis is not completed within zone A.

  *: Normal conditions refer to the following:

• Sea level
• Flat road
• Ambient air temperature: 20 - 30°C (68 - 86°F)
• Diagnosis is performed as quickly as possible under normal conditions.

  Under different conditions [For example: ambient air temperature other than 20 - 30°C (68 - 86°F)], diagnosis may also be performed.

Pattern 1:

• The engine is started at the engine coolant temperature of -10 to 35°C (14 to 95°F) [where the voltage between the ECM terminals 46 (Engine coolant temperature sensor signal) and 52 (Sensor ground) is 3.0 - 4.3V]. 
• The engine must be operated at idle speed until the engine coolant temperature is greater than 70°C (158°F) [where the voltage between the ECM terminals 46 (Engine coolant temperature sensor signal) and 52 (Sensor ground) is lower than 1.4V]. 

Pattern 2:

• When steady-state driving is performed again even after it is interrupted, each diagnosis can be conducted. In this case, the time required for diagnosis may be extended.

Pattern 3:

• Operate vehicle following the driving pattern shown in the figure.
• Release the accelerator pedal during decelerating vehicle speed from 90 km/h (56 MPH) to 0 km/h (0 MPH).

Pattern 4:

• The accelerator pedal must be held very steady during steadystate driving.
• If the accelerator pedal is moved, the test must be conducted all over again.

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

  *2: Checking the vehicle speed with GST is advised.

  Suggested Transmission Gear Position for CVT Models

  Set the selector lever in the D position.
