                 Diagnostic step
                      NOTICE


                 •      To implement the following steps, ensure that ABS 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.


                 1 .    DTC inspection
                 (a)    Ignition switch: OFF.
                 (b)    Connect the diagnostic apparatus.
                 (c)    Use the diagnostic apparatus, read the fault code.
