BRAKE ACTUATOR (for LHD) INSTALLATION

Note

While the battery is connected, even if the power switch is OFF, the brake control system activates when the brake pedal is depressed or the door courtesy switch turns on. Therefore during servicing of the brake system components, do not operate the brake pedal or open/close the doors while the battery is connected.

  29. READ VALUE OF ACCUMULATOR PRESSURE SENSOR OUTPUT VOLTAGE

    Tech Tips

    If removing and installing the No. 3 brake actuator tube, check for a brake fluid leak from the No. 3 tube connection area by monitoring the accumulator pressure sensor output value from the brake actuator. Directly checking for a brake fluid leak from the No. 3 tube connection area is difficult.


    1. Turn the power switch OFF.

    2. Connect the intelligent tester to the DLC3.

    3. Turn the power switch ON (IG).

    4. Operate the intelligent tester according to the display and select "DATA LIST".

      Skid control ECU:
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Accumulator Pressure Sensor Accumulator pressure sensor / min.: 0 V, max.: 5 V Specified value: 2.6 to 3.8 V -
    5. A01H0LB

      Depress the brake pedal 4 or 5 times to operate the pump motor, and check the output value on the intelligent tester with the motor stopped (not braking).

      OK
      Accumulator pressure sensor's output voltage drops 0.2 V or less for 30 seconds.

      If the voltage drops more than 0.2 V, there may be a brake fluid leak from the No. 3 brake actuator tube connection area. Remove the brake actuator and brake accumulator pump, and then repeat the procedures above from the retightening of the 2 union nuts of the No. 3 brake actuator tube.

      Torque:
      15 N*m  { 155 kgf*cm, 11 ft.*lbf }
