PROCEDURE


  1. CHECK IF SKID CONTROL ECU CONNECTOR IS SECURELY CONNECTED


    1. Check if the skid control ECU connector is securely connected.

      OK
      The connector is securely connected.

    NG

    CONNECT CONNECTOR TO ECU CORRECTLY

    OK

  2. CHECK BATTERY


    1. Check the battery voltage.

      Standard voltage
      11 to 14 V

    NG

    CHECK OR REPLACE CHARGING SYSTEM OR BATTERY

    OK

  3. CHECK SLIP INDICATOR LIGHT


    1. Turn the ignition switch to OFF and disconnect the skid control ECU connector.

    2. A0136MKE37

      Ground terminal IND of the skid control ECU.

    3. Turn the ignition switch to ON.

    4. Check the SLIP Indicator light.

      OK
      IND - GND Condition Illumination Condition
      Connecting ON
      Disconnecting OFF

      Tech Tips


      • When the VSC warning light comes on, ground failure or open circuits in the brake actuator should be considered.

      • When the VSC warning light does not come on, opens in the wire harness among the combination meters or abnormalities in the meter circuit should be considered.
