DTs may be stored if brake fluid leaks, wheel cylinder vibrates due to uneven wear of the brake disc rotor, or foreign matter enters the solenoid valve. DTs may be stored if the line pressure drops during air bleeding.

HEK RAKE FLUID LEAKAGE (a) (b) heck that there is no fluid leakage in the brake line between the brake actuator and the wheel cylinder which is the cause of DTs. heck that the brake is not dragging. OK: There is no fluid leakage or dragging. NG REAIR OR RELAE ALIALE ART OK 2 ERFORM AIR LEED (SEE AGE 24) (a) leed the air out of the front and rear systems (see page 24). REONFIRM DT (a) lear the DTs. (b) Turn the power switch ON (READ). (c) heck the same DTs are recorded (see page 09).

OK: rake pedal is not vibrates during braking rius reliminary Release (RM0U) 249

9 0086 DIAGNOSTIS ELETRONIALL ONTOROLLED RAKE SSTEM HINT: The brake pedal does not kick back due to wheel cylinder piston vibration during E control. If the brake pedal stroke sensor connector is disconnected, the failsafe function prohibits E control. The active test does not prohibit E control when the vehicle is running, so disconnect the stroke sensor connector and carry out inspection. Disc wear can be checked by measuring the disc thickness.
