Hint

: start the inspection from step 1 in case of using the hand–held tester and start from step 2 in case of not using hand–held tester.

1 Inspect brake actuator assy

  1. Select the datalist mode on the hand–held tester.
  2.  check the operation sound of the abs pump motor when operating it with the hand–held tester.

    Ok: the operation sound of the abs pump motor should be heard.

2 Inspect skid control ecu terminal voltage(+bm terminal voltage)

2 Inspect skid control ecu terminal voltage(+bm terminal voltage)

  1. Disconnect the skid control ecu connector.
  2.  measure the voltage between terminal +bm (24) and gnd (23) of skid control ecu harness side connector.
