Windscreen wipers are a factor of safety and control of the vehicle. These components are made in the form of movable arms that have rubber elements at the ends. Their function is to initiate a wiping process. Each end of the arm is connected by a hinge to the rods, which allows the coupling and ensures a synchronized movement. The wiper system is activated by a geared motor which is powered by a relay.
The B2301 OBD2 fault code is set when the instrument cluster detects a lower than the expected voltage on the input circuit of the Wiper Mode Switch.
