PINPOINT TEST S: THE LOW WASHER FLUID INDICATOR IS NEVER/ALWAYS ON

Test S1:

Test S2-S3:

Test S4-S7:

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 standard corporate protocol (SCP) communication network, circuits 4-EG8 (GY/VT) and 5-EG8 (BU/WH).

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