Fluid Level Sensor Description
WARNING: This page is about a different car, the 2006 Suzuki Verona. However, it is still accessible from the selected car via links, so may be relevant.
The master cylinder reservoir is equipped with a fluid level sensor. The sensor will activate the BRAKE lamp when the fluid level is low. The BRAKE lamp is also activated by the parking brake lever, and it turns on for a bulb test when the ignition is ON and the engine is not running. For diagnosis of the BRAKE lamp, refer to Brake Lamp Warning Circuit .
