                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.


           1 .    DTC inspection
           (a)    Ignition switch: OFF.
           (b)    Connect the diagnostic apparatus.
           (c)    Use the diagnostic apparatus, read the fault code.
           (d)    Confirm whether there is a fault code related to steering sensor?
           Is the inspection result normal?

           YES>To step 2.
           NO>Intermittent trouble exists.


           2 .    Check fuse.
           (a)    Ignition switch: OFF.

                                                      (b)    Check fuse in the indoor fusebox:

           Is the inspection result normal?
           YES>To step 3.
           NO> Replace fuse.


           3 .    Check steering sensor power supply circuit
           (a)    Ignition switch: OFF.
           (b)    Disconnect the battery negative cable.
           (c)    Disconnect steering sensor connector C059.
