Driving Pattern
- Turn the ignition switch to LOCK (0), and wait at least 6 hours.
- Start the engine, and let it idle for at least 10 seconds.
- Do not use an engine block heater because the engine coolant temperature will not stay equal during engine stop.
- When freeze data is stored, test the vehicle under an ambient temperature close to the intake air temperature in the freeze data.
- When an ambient temperature extremely changes, malfunction judgment may not execute. Avoid extreme temperature changing condition after or before engine start. (When the vehicle is parked in the garage, open the shutter to introduce outside air; then start the engine.)
