TERMINAL INSPECTION


  1. for LHD Models.



      C197055E01

    1. Disconnect the connector and measure the voltage or resistance on the wire harness side.

      (to skid control ECU)

      HINT:
      Voltage cannot be measured with the connector connected to the skid control ECU as the connector is watertight.
