1. Switch the ignition to off.

2. Disconnect the brake pipe flare nut.






3. Disconnect the brake hose (LF).

4. Remove the bracket.

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

8. Select the "MCYLI_P" PID. 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. DSC HU/CM Removal/Installation

11. Remove the SSTs after the inspection and install the bracket, brake hose and brake pipe to their original positions. Brake Hose (Front) Removal/Installation
