Test E: The WASHER FLUID LEVEL LOW Message Is Inoperative/Always On

PINPOINT TEST E: THE WASHER FLUID LEVEL LOW MESSAGE IS INOPERATIVE/ALWAYS ON

Normal Operation
The instrument cluster (IC) provides a reference voltage to the washer fluid switch through circuit CMC20 (VT). The washer fluid switch is grounded through circuit GD123 (BK/GY). When the washer fluid is low, the washer fluid switch closes to ground, pulling the reference voltage low. When the instrument cluster (IC) detects the washer fluid input pulled low, it displays the WASHER FLUID LOW warning.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Washer fluid level switch
- Instrument cluster (IC)
