                                                        e. Measure the  voltage between the B014 terminal 10 and   IN
                                                        the ground with the multimeter in voltage gear.
                                                        Standard voltage:                                         DI

                                                          Multimeter connecting terminal   Standard value
                                                               B004(10)-grounding      Storage battery voltage    EG


                                                                                                                  TR

              Check if the result is ok?                                                                          AX
              Yes>go to Step 3.
              No > repair or replace the open-circuit wire harness of combination instrument power supply.
                                                                                                                  FR
              3. Check the earth circuit of combination instrument.

              a. Ignition switch: LOCK.
                                                                                                                  ST
              b. Disconnect the connector B014 of combination instrument.

                                                        c. Take a multimeter to measure resistance between No. 32
                                                        terminal of B014 and grounding.                           BR
                                                        Standard resistance:

                                                          Multimeter connecting terminal   Standard value         BW
                                                               B004(32)-grounding           About 0Ω

                                                                                                                  EL


              Check if the result is ok?
              Yes>go to Step 4.
              NO>repair or replace the harness.

              4. Check the combination switch
                                                           Caution

              If the combination instrument is broken, normally non-professional personnel cannot check and repair
              precisely. At present often using the substitution judgment method for service.


              a. Replace with a new or normal combination instrument.
              b. Connect the circuit, restart the ignition switch and check if the failure is fixed.
                                                           Caution
              The combination instrument for replacement must be the same specification as previously used.
              Is the test result ok?
              Yes>repair or replace the combination instrument.
                                                           Caution

              Internal  combination  instrument  service  needs  professional  personnel.  Others  shall  not  dismount
              anything.

              NO>retest the above steps.
