Brake Fluid Pressure Sensor Inspection
- Switch the ignition off.
- Disconnect the brake pipe from the brake hose (LF).
- Install the SSTs to the brake pipe as shown in the figure.
- 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_F_P_R" PID.
- 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 .)
- After the inspection, remove the SSTs, install the brake hose and brake pipe to the original positions. (See FRONT BRAKE HOSE REMOVAL/INSTALLATION [WITH 4-POT OPPOSED PISTON CALIPER] .) (See FRONT BRAKE HOSE REMOVAL/INSTALLATION [WITH SINGLE PISTON FLOATING CALIPER] .)
- Bleed the air from the brake line. (See BRAKE FLUID AIR BLEEDING .)
