Bleed the brake line and the SSTs of air. Bleed the air form the SSTs using bleeder screw A.
Connect the M-MDS to the DLC-2.
Select the "BRK_FLD_PRES" PID. (See PID/DATA MONITOR INSPECTION .)
Start the engine.
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 HU/CM. (See DSC HU/CM REMOVAL/INSTALLATION [L.H.D. (US)] .)
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. (See FRONT BRAKE HOSE REMOVAL/INSTALLATION (US) .) (See BRAKE FLUID AIR BLEEDING (US) .)
