                      NOTICE


                 •      To implement the following steps, ensure that ABS/ESP is grounded properly.
                 •      Before conducting electric diagnosis, do refer to the reference circuit diagram
                        and the element information.
                 •      Before conducting measurement, check the pins of connectors for rupture,
                        looseness and rust, and ensure that the pins are contacted properly.
                 •      If the connection is good, check the sensor signal voltage when moving the
                        connector and harness. If a fault occurs, the voltage display on the diagnostic
                        instrument will change.
