1. Remove the fan control module connector.
2. Turn the ignition switch to the "ON" position, and measure the voltage between the harness-side connector terminals. Standard value: Battery positive voltage
3. Connect the fan control module connector, and disconnect the condenser fan motor connector.
4. Ensure that the A/C switch is off, and start the engine and run it at idle.
5. Measure the voltage between the fan control module-side connector terminals. Standard value: 1 V or less
6. Turn the A/C switch to the "ON" position. WARNING: Stay clear of the fan when the fan starts running.
7. Measure the voltage between the fan control module-side connector terminals while the fan is running. The voltage should repeat the values 1) and 2) below. Standard value: 1) 8.2+/-2.6 V 2) 2) Battery positive voltage+/-2.6 V
8. If the voltage does not repeatedly change as indicated, replace the fan control module.
