쐌 The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driv-
ing 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)], diag-
nosis may also be performed.
Pattern 1:
쐌 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 59 and ground is 3.0 - 4.3V).
쐌 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 59 and ground is lower than 1.4V).
쐌 The engine is started at the tank fuel temperature of warmer than 0°C (32°F) (where the voltage
between the ECM terminal 60 and ground is less than 4.1V).
Pattern 2:
쐌 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:
쐌 The driving pattern outlined in *2 must be repeated at least 3 times.
Pattern 4:
쐌 Tests are performed after the engine has been operated for at least 17 minutes.
쐌 The accelerator pedal must be held very steady during steady-state driving.
쐌 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 below at least 10 times.
쐌 During acceleration, hold the accelerator pedal as steady as possible.
SEF414S
*3: Checking the vehicle speed with CONSULT-II or GST is advised.
Suggested Transmission Gear Position for A/T Models
Set the selector lever in the “D” position with the overdrive switch turned ON.
Suggested upshift speeds for M/T models
Shown below are suggested vehicle speeds for shifting into a higher gear. These suggestions relate to fuel
economy and vehicle performance. Actual upshift speeds will vary according to road conditions, the weather
and individual driving habits.
