Fluid Level Sensor
A fluid level sensor is included in the hydraulic unit reservoir cap. The sensor consists of a float and reed switch which closes when low fluid is detected. The fluid level sensor is used as an input to both the BCM and the EBCM. A low fluid input to the BCM will cause the LOW BRAKE FLUID message to be displayed on the CCDIC at key-on. The EBCM will disable anti-lock function and illuminate the Red BRAKE warning indicator lamp if a low fluid input is received.
