Diagnostic procedure
- Make sure that the engine coolant temperature is less than 30°C (86°F).
- Drive according to the drive pattern described below.
NOTE:
- There is no given transition time between idling and cruising.
- Driving at constant speed only on a downhill causes smaller engine load and may result in failure to obtain a right diagnostic result.
- When the engine stops while performing drive cycle F, perform it again from the state of procedure 1).
