PINPOINT TEST A: RED BRAKE WARNING INDICATOR ALWAYS ON

Tests A1 - A4:

Normal Operation
The red brake warning indicator is located on the instrument cluster and will illuminate at prove out, when the brake fluid in the brake master cylinder reservoir is below an acceptable level, and when the parking brake is engaged.

Possible Causes
^ low brake fluid level
^ parking brake engaged
^ an open circuit in the brake fluid level switch return ground circuit 31-GC7 (BK/BU)
^ a short to ground in circuit 8-GC7 (WH/RD)
^ an open circuit in the brake fluid level switch input signal circuit 8-GC7 (WH/RD)
^ a defective low brake fluid level switch
^ front electronic module (FEM)
^ instrument cluster
