Warning Lamp, Brake Fluid Level

Warning lamp, brake fluid level

!:

Schematic:

The brake fluid warning lamp warns the driver if the level of fluid in the reservoir is too low. The lamp will also go on if there is a fault in the ABS system.

If the brake fluid level is too low, the level switch closes and pin 13 in the main instrument unit is grounded, whereupon the control module lights the lamp. At the same time, the central warning lamp is lit and at engine speeds above 300 rpm, MIU sends a request to SID to activate the acoustic signal.

The main instrument unit lights the brake fluid level warning lamp for 3 seconds when the ignition is turned on.
