CIRCUIT OPERATION
• The cooling fan motor drive control unit is pow-
ered from fusible link (2).
• The engine-ECU <M/T> or engine-A/T-ECU
<A/T> uses input signals from the A/C switch, the
water temperature sensor unit and the vehicle
speed sensor <M/T> or the output shaft speed
sensor <A/T> to control the speed of the cooling
fan motor (L.H.) and the cooling fan motor (R.H.)
<4G1 (Vehicles with A/C)> or A/C condenser fan
motor <4G6>.
