System DescriptionINFOID:0000000005398266
INPUT/OUTPUT SIGNAL CHART
*1: The ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: This signal is sent to ECM via the CAN communication line.
SYSTEM DESCRIPTION
ECM controls cooling fan speed corresponding to vehicle
speed, engine coolant temperature, refrigerant pres-
sure, air conditioner ON signal. Then contro l system has 3-step control [HIGH/LOW/OFF].
