Removal & Installation

For fan control module removal and installation, refer to the Radiator Replacement procedure in the Engine Mechanical Section.

Testing
  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

  6. Turn the A/C switch to the "ON" position.
  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) Battery positive voltage ± 2.6 V
  8. If the voltage does not repeatedly change as indicated, replace the radiator fan motor.
