Component Description

WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.

Low Washer Fluid Level Switch

The low washer fluid level switch is a normally closed switch that is hardwired to the IPC through a single signal wire and is grounded to a body ground through a separate circuit. The IPC provides a reference voltage to the low washer fluid level switch. When the washer fluid level is low, the float drops closing the switch and pulling the reference voltage low. When the washer fluid level is high, the float lifts off the switch and opens the circuit to the IPC sending the reference voltage high.

Steering Wheel Switch - Message Center

The message center switch is the upper LH steering wheel switch and is comprised of 5 buttons. The message center switch uses different resistance values associated with each specific button. The IPC sends out a reference voltage to the upper LH steering wheel switch on the input circuit and monitors the voltage drop. The voltage drop varies depending upon the resistance of the specific button pressed, providing indication to the IPC which switch is pressed.
