• 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 terminal 93 and 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 terminal 93 and ground is lower than 1.4V). 
• The engine is started at the fuel tank temperature of warmer than 0° C (32° F) (where the voltage between the ECM terminal 75 and ground is less than 4.1V). 

  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:

  • The driving pattern outlined in ^* 2 must be repeated at least 3 times.

    Pattern 4:

  • Tests are performed after the engine has been operated for at least 17 minutes.
  • The accelerator pedal must be held very steady during steady-state 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: Operate the vehicle in the following driving pattern.

    1. Decelerate vehicle to 0 km/h (0 MPH) and let engine idle.
    2. Repeat driving pattern shown in Fig 2 at least 10 times.
  • During acceleration, hold the accelerator pedal as steady as possible.

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

Suggested Transmission Gear Position 

Set the selector lever in the D position with the overdrive switch turned ON.
