Brake Fluid Pressure Sensor Inspection

Switch the ignition to off.
Disconnect the brake pipe flare nut.

Fig 1: Clip, Brake Pipe And Brake Hose
Remove the clip and disconnect the brake hose.
Install the SSTs to the brake pipe as shown in the figure.

Fig 2: Installing SSTs To Brake Pipe
Perform air bleeding of the SST and brake line from bleeder screw A.
Connect the M-MDS to the DLC-2.
Select the "MCYLI_P" PID. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)] .)
Start the engine.
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 .)
Remove the SSTs after the inspection and install the brake hose, clip and brake pipe to their original positions. (See BRAKE HOSE (FRONT) REMOVAL/INSTALLATION .)
Perform air bleeding of the brake line. (See BRAKE FLUID AIR BLEEDING .)
