CIRCUIT OPERATION
- MFI relay is built into the IPDM E/R.
- In the IPDM E/R, the voltage from the 12V battery is applied.
- The ECM connector terminal number 95 turns ON the power transistor in the unit, and the relay turns ON through electricity being supplied to the MFI relay coil.
- When the MFI relay turns ON, 12V battery voltage is supplied from the IPDM E/R to the ECM, the sensor, and the actuator.
TECHNICAL DESCRIPTION
ECM set the information such as the learned value and so on in the memory of ECM.
DESCRIPTIONS OF MONITOR METHODS
To check whether the information such as the learned value and so on is set in the memory of ECM.
MONITOR EXECUTION
Once per driving cycle.
MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC set in memory for the item monitored below)
Sensor (The sensor below is determined to be normal)
DTC SET CONDITIONS
Check Condition
- Power supply mode of electric motor switch is ON.
Judgment Criterion
- The latest data that was flashed while the power supply mode of the electric motor switch was OFF are not set correctly for 10 times.
FAIL-SAFE AND BACKUP FUNCTION
None.
OBD-II DRIVE CYCLE PATTERN
None.
