MPI <4G9> – Troubleshooting 13C-74 DATA LIST REFERENCE TABLE Caution NOTE 10 % higher than the standard frequency. *2. The injector drive time represents the time when the cranking speed is at 250 r/min or below when the power supply voltage is 11 V. *3. In a new vehicle [driven approximately 500 km or less], the injector drive time is sometimes 10 % longer than the standard time. *4. In a new vehicle [driven approximately 500 km or less], the step of the stepper motor is sometimes 30 steps greater than the standard value. L It will not be displayed when service data of the check mode is selected.
