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. Refer to "COOLING FAN CONTROL : SYSTEM DIAGRAM " (VQ37VHR) or "COOLING FAN CONTROL : SYSTEM DIAGRAM " (VK56VD).

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. Refer to "POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM : SYSTEM DIAGRAM ".
