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) 

NOTE:



The brake fluid pressure sensor is integrated into the DSC 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.

8. Select the "MCYLIP" 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.)  

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.
