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

Test T1-T5:

Test T5-T6:

Test T7-T10:

Normal Operation
The low washer fluid switch is hardwired to the bussed electrical center (BEC) and to the SJB through circuit 81 (RD/LG) and grounded through circuit 1205 (BK). The SJB 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 914 (TN/OG) and 915 (PK/LB).

Possible Causes
- circuit 81 (RD/LG) open, short to ground or power
- circuit 1205 (BK) open
- low washer fluid switch
- BEC
- SJB
- instrument cluster
