Brake Fluid Level Sensor

If the hydraulic fluid in the reservoir falls to a predetermined low level, the switch contacts close and provide a ground signal to the Central Junction Box (CJB). The CJB then sends a high speed Controller Area Network (CAN) powertrain signal to the Instrument Cluster (IC) and the ABS. On receipt of the signal:

• The IC illuminates the red brake warning indicator, and the message center displays the critical warning indicator (red warning triangle) and the message Brake Fluid Low.
• The ABS disables Dynamic Stability Control (DSC) functions and sends a high speed CAN powertrain bus signal to the IC to continuously illuminate the DSC warning indicator.
