Beretta V6-3100 3.1L MFI VIN M (1994)
Brake Warning Indicator: Description and Operation
Circuit Operation
Battery voltage is applied to the BRAKE Indicator when the Ignition Switch is in "RUN," "BULB TEST" or "START." Three switches are connected to
the BRAKE Indicator. When any one of these switches closes, ground is provided and the indicator lights.
The Ignition Switch provides a ground when it is in the "BULB TEST" and "START" positions.
The Park Brake Switch provides a ground when the Park Brake is applied.
If the vehicle is equipped with Daytime Running Lights, the Park Brake Switch applies grounds to the BRAKE Indicator via a diode within the DRL
Module.
The Brake Fluid Level Switch closes to light the BRAKE Indicator when there is low brake fluid in one of the two hydraulic brake systems. This could
be caused by a leak in one of the brake lines. The switch can be reset to an open position by refilling the reservoir; however, this can only be
accomplished after the faulty system has been repaired.
The Electronic Brake Control Module (EBCM) will cause the BRAKE Indicator to light only when the Antilock Brake system degrades the base brake
system.
