Note: It is more convenient to check the brake fluid level sensor with an assistant.
Examination
1. Prepare the car for repair work.
2. Briefly turn the key in the ignition and turn on the starter to make sure that the low brake fluid indicator light is working properly. To further check the sensor, leave the ignition on.
Note: If the brake fluid low indicator lamp is working properly, it should light when the starter is turned on. A faulty lamp should be replaced and only then continue checking.
3. Pressing from above, we sink the float rod of the sensor. At the same time, the control lamp for insufficient brake fluid level should light up on the instrument panel.
Note. If the indicator lamp does not light, then the terminals in the connector itself may be oxidized, there is a break in the wire, or the sensor is faulty. To ensure the integrity of the wires, it is enough to short-circuit the terminals of the connector. The indicator lamp should light. A faulty brake fluid level sensor must be replaced.
Removal
1. Turn off the ignition.
2. Disconnect the wiring harness connector from the sensor.
3. Unscrew the cap of the master brake cylinder reservoir.
By removing the brake fluid level sensor float from the master brake cylinder reservoir, we remove the sensor. We replace the faulty brake fluid level sensor as an assembly.
