The brake fluid warning lamp tells the driver when the level of the fluid in the reservoir is too low. The lamp also goes on if there is a fault in the ABS system.

If the brake fluid level is too low, the level switch will close and pin 13 on the main instrument unit will be grounded, whereby the control module will turn on the lamp. The central warning lamp will come on at the same time and at engine speeds above 310 RPM, MIU will send 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.
