BRAKE FLUID PRESSURE SENSOR INSPECTION

id041500801500

  Note
  • The brake fluid pressure sensor is integrated into the DSC HU/CM and installed to the brake line of LF—RR brake system. Therefore, perform the brake fluid pressure sensor inspection with the SST installed to the brake pipe on the left front wheel.

1. Turn the ignition switch to the LOCK position.

2. Loosen the brake pipe flare nut using the commercially available flare nut wrench.

3. Disconnect the brake pipe.

4. Remove the bolt and disconnect the brake hose.

5. Install the SSTs to the brake pipe as shown in the figure.

6. Perform air bleeding of the SST and brake line from bleeder screw A.

7. Connect the M-MDS to the DLC-2.

8. Select the “MCYLI P” PID. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)

9. Start the engine.

10. Depress the brake pedal, and verify that the fluid pressure value of the SST (gauge) and the value shown on the M-MDS are equal.

  • If the fluid pressure values are different, replace the DSC HU/CM. (See DSC HU/CM REMOVAL/INSTALLATION.)

11. Remove the SSTs after the inspection and install the brake hose, bolt and brake pipe to their original positions.

12. Perform air bleeding of the brake line. (See AIR BLEEDING.)
