Low speed control
In IGN2 ON State, if there is wiper low input (LIN communication), then wiper low relay output is turned ON.
High speed control
In IGN2 ON State, if there is wiper high input (LIN communication), then both wiper low and wiper high relay outputs are turned ON.
Speed sensing intermittent wiper (without rain sensor option) Vehicle speed and intermittent time volume control the interval time of intermittent wiper.
In IGN2 ON State, if there is wiper intermittent input (LIN communication), then wiper is controlled by vehicle speed and wiper intermittent.
