    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.
    1. Standard value: 
      1. 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.
