Normal Operation

Under normal operation, when any wiper mode except OFF is selected, the multifunction switch provides a combination of grounds to the smart junction box (SJB) through circuits (G/V), (V/W), (L/O) and (BR/W). The SJB interprets this ground combination to determine the desired wiper mode.
