PINPOINT TEST AF: THE BRAKE FLUID LEVEL DISPLAY IS NEVER/ALWAYS ON

Test AF1-AF2:

Normal Operation
The SJB is hardwired to the brake fluid level switch. When the brake fluid level is low, the SJB sends a command to the instrument cluster over the SCP communication network, circuits 914 (TN/OG) and 915 (PK/LB), to illuminate the BRAKE FLUID LOW warning display.

Possible Causes
- instrument cluster
- SJB
