EC-38 < SYSTEM DESCRIPTION > [VQ35DE] SYSTEM When the SET/COAST switch is pressed during cruise control driving, decrease vehicle set speed until the switch is released. And then ASCD will maintain the new set speed. RESUME OPERATION When the RESUME/ACCELERATE switch is pressed after cancel operation other than pressing MAIN switch is performed, vehicle speed will return to last set speed. To resume vehicle set speed, vehicle condition must meet following conditions. • Brake pedal is released • Selector lever is in the P and N positions • Vehicle speed is greater than 40 km/h (25 MPH) and less than 144 km/h (89 MPH) COOLING FAN CONTROL INFOID:0000000009178041 SYSTEM DIAGRAM *: ECM determines the start signal status by the signals of engine speed and battery voltage. SYSTEM DESCRIPTION ECM controls cooling fan speed corresponding to engine speed, engine coolant temperature, refrigerant pres- sure, battery voltage, vehicle speed, A/C ON signal, A/C evaporator temperature, target A/C evaporator tem- perature and blower fan ON signal. Cooling fan speed request signal is sent to IPDM E/R from ECM via the CAN communication line. Then, IPDM E/R sends ON/OFF pulse duty signal to cooling fan control module. Corresponding to this ON/OFF pulse duty signal, cooling fan control module gives cooling fan motor operating voltage to cooling fan motors. Cooling fan speed is controlled by duty cycle of cooling fan motor operating voltage sent from cooling fan control module.
