Using Hi-Scan

The injector drive time is when the supply voltage is 11V and the cranking speed is less than 250 RPM.
When engine coolant temperature is lower than 0°C (32°F), the ECU fires all four cylinders simultaneously.
When the vehicle is new (within initial operation of about 500 km (300 miles), the injector drive time may be about 10% longer.
