Automatic Mode

When the wiper switch is moved to AUTO position (Wiper Auto Switch=ON & Wiper Int Switch=ON) and (IGN Switch FAM = IGN), the Rain sensor is considered to be in "AUTOMATIC" mode.

1. If the wiper switch has been left in AUTOMATIC Mode with the vehicle ignition OFF, and then the vehicle ignition switch is turned on, the FAM transmits single wiping command.
2. The FAM transmits a single wiping command whenever rain has been detected (Rain Detected signal from Rain sensor) and the wiper switch is moved to the AUTO position. But The FAM does not transmit single wiping command when the wiper switch is moved to the AUTO position and OFF signal is being received from Rain sensor. But if the wiper switch is moved to AUTO position for the first time since vehicle ignition switch is turned on then the FAM transmits single wiping command regardless of Rain Detected or OFF signal.
3. Sensitivity Adjustment Function

   The drive may adjust the rain sensor performance by adjusting the sensitivity input. When in AUTOMATIC mode, the FAM transmits single wiping command each time the SENSITIVITY is adjusted upward to a more sensitive setting (downward more then one step). This single wiping command will only be transmitted if Rain Detected signal is being received from the Rain sensor. If the sensitivity adjustment is adjusted upward more than one sensitivity, the FAM will transmit single wiping command unless the time between Increases is more than 2 seconds.
