      Front view of wire harness connector

      (to Skid Control ECU (Brake Actuator Assembly))

      Disconnect the A120 skid control ECU (brake actuator assembly) connector.

    2. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      A120-25 (+BS) - Body ground Always 11 to 14 V
      A120-25 (+BS) - A120-38 (GND1) Always 11 to 14 V
      A120-28 (IG1) - Body ground Ignition switch ON 11 to 14 V
      A120-28 (IG1) - A120-38 (GND1) Ignition switch ON 11 to 14 V
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE TERMINAL)

    OK

  4. CHECK HARNESS AND CONNECTOR (GND1 TERMINAL)


    1. A01LYMTC02
      *a

      Front view of wire harness connector

      (to Skid Control ECU (Brake Actuator Assembly))

      Turn the ignition switch off.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      A120-38 (GND1) - Body ground Always Below 1 Ω
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (GND1 CIRCUIT)

    OK

  5. REPLACE BRAKE ACTUATOR ASSEMBLY


    1. Replace the skid control ECU (brake actuator assembly).
