Brake Fluid Pressure Sensor/Switch: Testing and Inspection

BRAKE FLUID PRESSURE SENSOR INSPECTION





1. Turn the ignition switch off.
2. Install the SSTs to the master cylinder.

Note: Install the SST (49 N043 001) to the master cylinder using a commercially available flare nut wrench.

Flare nut across flat: 12 mm (0.47 inch)
3. Bleed the air from the SSTs and the brake line. (Bleed air from the SSTs through air bleeding valve A.)





4. Connect the WDS or equivalent to the DLC-2.
5. Select the MCYLI P PID.
6. Start the engine.
7. Depress the brake pedal, and confirm that the fluid pressure value of the SST (Gauge) and the value shown on the WDS or equivalent are equal.
^ If the fluid pressures are different, replace the DSC HU/CM.
