BRAKE FLUID PRESSURE SENSOR INSPECTION

id041800817300

  Note
  • The brake fluid pressure sensor is integrated into the DSC/RSC HU/CM and installed to the brake line of RF—LR 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 OFF position.

2. Disconnect the brake pipe flare nut area using a commercially available flare nut wrench.

3. Remove the clamp and disconnect the brake hose.

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

5. Bleed the brake line and the SSTs of air. Bleed the air from the SSTs using bleeder screw A.

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

7. After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

  • When using the IDS (laptop PC)
    1. Select “DataLogger”.
    2. Select “Modules”.
    3. Select “ABS”.

  • When using the PDS (Pocket PC)
    1. Select “Module Tests”.
    2. Select “ABS”.
    3. Select “DataLogger”.

8. Select the “MCYLI P” PID.

9. Start the engine.

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

  • If the fluid pressures are different, replace the DSC/RSC HU/CM. (See DSC/RSC HU/CM REMOVAL/INSTALLATION [L.H.D.].) (See DSC/RSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)

11. After the inspection, remove the SSTs, install the brake hose, clamp, and brake pipe to the original positions, and then bleed the air from the brake line.
