Comment. It is more convenient to check the sensor with an assistant.
Examination
1. We prepare the car for work (see «Preparing the car for maintenance and repair»).
2. Turn on the ignition.
3. Pressing from above, we sink the sensor float rod. At the same time, the warning lamp for insufficient brake fluid level should light up on the instrument panel.
Recommendation. If the control lamp does not light up, the terminals in the connecting block may have oxidized or the sensor is faulty. To make sure that the sensor is malfunctioning, it is enough to close the terminals of the connecting block between each other. If the control lamp lights up, the sensor is faulty and must be replaced.
Removing
1. Turn off the ignition.
2. Disconnect the wiring harness block from the sensor.
3. Turn off the reservoir cap of the main brake cylinder. We remove the sensor float from the tank and remove the sensor.
4. We replace the defective sensor as an assembly.
Installation
Install the sensor in reverse order.
