N4-N6:






Normal Operation
The low washer fluid switch is hardwired to the front electronic module (FEM) through circuit 8-GC8 (WH/BU) and grounded through circuit 31-GC8 (BK/OG). The FEM monitors the washer fluid level and sends the low washer fluid data to the instrument cluster over the communication network.

Possible Causes
- circuit 8-GC8 (WH/BU) open, or short to ground
- circuit 31-GC8 (BK/OG) open
- low washer fluid switch
- FEM
- instrument cluster
