Inspection Procedure 9
CIRCUIT OPERATION- The fan control module is powered from fusible link number 5.
- The ECM [M/T] or PCM [A/T] judges the required revolution speed of radiator fan motor and condenser fan motor using the input signals transmitted from A/C switch, automatic compressor controller, vehicle speed sensor and engine coolant temperature sensor. The ECM [M/T] or PCM [A/T] activates the fan control module to drive the radiator fan motor and condenser fan motor.
TECHNICAL DESCRIPTION
The cause could be a malfunction of the condenser fan motor or of the fan control module.
TROUBLESHOOTING HINTS
- Malfunction of condenser fan motor
- Malfunction of fan control module
DIAGNOSIS
STEP 1. Check The Condenser Fan Motor.
If condenser fan is faulty, go to Step 2.
If normal, replace the radiator fan motor and fan control module assembly. Then go to Step 3.
STEP 2. Check The Fan Control Module.
If the fan control module is faulty, replace it. Then go to Step 3.
If normal, go to Step 3.
STEP 3. Check The Symptoms.
Confirm that the condenser fan operates correctly.
