    OK

  2. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - DLC3)


    1. Disconnect the A46 skid control ECU (brake actuator assembly) connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      A46-15 (TS) - C16-12 (TS) Always Below 1 Ω
      A46-15 (TS) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK
