Brake Fluid Pressure Sensor Inspection

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..

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..
