           3 .    Check the harness and connectors (horn relay - BCM control unit)
           (a)    Ignition Switch: OFF.
           (b)    Unplug the horn relay R13.


                                                      (c)    Disconnect connector C035 of BCM control
      04                                                     unit.

                                                      (d)    Measure the electrical resistance based on
                                                             the value in the following form.

                                                             Standard electrical resistance (check
                                                             whether there existent an open circuit)
                      C035
                                                       Multimeter connection          Standard value
                                                       R13（2）-C035（D18）                   ＜ 2 Ω






                         R13


                                            ftwxd041382

           Check whether the result is normal?

           Yes> go to step 4
           No > Maintenance or replace harness.

           4 .    Check the harness and connector (BCM control unit - clock spring)

           (a)    Ignition Switch: OFF.
