LS V8-3.9L VIN A (2003)
Test AM4-AM6
Normal Operation
The washer fluid level switch circuit 8-GC8 (WH/BU) is open when the washer fluid level is high. When the washer fluid level is low, the switch will
close circuit 8-GC8 (WH/BU) with the ground circuit 31-GC8 (BK/OG) to signal the FEM that the washer fluid level is low. The FEM communicates
the washer fluid level status to the instrument cluster over the SCP network. The message center uses that information to display the low washer fluid
message.
