           (a)    Disconnect battery negative cable.
           (b)    Unplug the relay R4 of starter.

                                                      (f)    Measure the voltage based on the value in
                                                             the following form.

                                                         R04(1)- ground                    < 2Ω















           Check whether the result is normal?
           Yes> go to step 4

           No > Maintenance or replace harness.

           4 .    Check the relay of air conditioner compressor
           (a)    Disconnect battery negative cable.
           (b)    Unplug the relay R14 of air conditioner compressor

                                                      (c)    Check the relay of air conditioner compressor.

                                                          situation            1-2           Breakover

                                                        Apply power
                                                       supply voltage
                                                         to position           3-5              <2Ω
                                                       between stitch
                                                          3 and 5,



           Check whether the result is normal?
           Yes> go to step 5

           No > Replace the relay of air conditioner compressor, and verify again whether the
           failure exists.

           5 .    Check the harness and connectors (relay of air conditioner compressor - ground)
