IPDM E/R (Without I-Key)

SYSTEM

POWER CONTROL SYSTEM : System Description


COOLING FAN CONTROL

IPDM E/R outputs pulse duty signal (PWM signal) to the cooling fan control module according to the status of the cooling fan speed request signal received from ECM via CAN communication. System Diagram.

CAUTION:
After ignition switch OFF, IPDM E/R turn the cooling fan relay ON and outputs pulse duty signal (PWM
signal) to the cooling fan control module according to the request signal from ECM for cooling the engine according to the situation.

ALTERNATOR CONTROL

IPDM E/R outputs power generation command signal (PWM signal) to the alternator according to the status of the power generation command value signal received from ECM via CAN communication. System Diagram.
