BRAKE FLUID PRESSURE SENSOR INSPECTION

1. Turn the ignition switch off.

2. Install the SSTs to the master cylinder as shown in the figure.






NOTE:
- When installing the SST (49 D043 0A0) to the master cylinder, use a commercially available flare nut wrench (flare nut across flat 12 mm {0.47 in}).

3. Bleed the brake line and the SSTs of air. (Bleed the SSTs of air using air bleed valve A.)

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






5. Select the "MPRETDR" PID. On-Board Diagnosis [Dynamic Stability Control (DSC)]

6. Start the engine.

7. 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. DSC HU/CM Removal/Installation

8. Remove the SSTs after the inspection and install the brake pipe to their original positions. Service and Repair Service and Repair

9. Perform air bleeding of the brake line. Service and Repair
