Radiator Cooling Fan Control Module: Testing and Inspection

FAN CONTROLLER CHECK
1. Remove condenser fan motor connector.
2. Start the engine and run it at idle.
3. Turn the A/C switch to ON and maintain the coolant temperature at 80°C (176°F) or less.





4. When measuring the voltage between the fan controller-side connector terminals, check that the value changes repeatedly as indicated by (1) - (3) below.
1) 0 V
2) 8.2 ± 2.6 V
3) Battery positive voltage ± 2.6 V
5. If the voltage does not repeatedly change as indicated, replace the radiator fan motor and the fan controller assembly.
