1.  Switch the ignition to off.

2.  Install the SSTs to the master cylinder (secondary side) 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 “MCYLI_P” PID. (See 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. (See DSC HU/CM REMOVAL/INSTALLATION.)
