                                                        c. The positive and negative poles of bulb are connected to

                                                        the  positive  and  negative  poles  of  battery  respectively.
                                                        Check if the bulb can be on.                              DI

              Check if the result is ok?                                                                          AX
              Yes>go to Step 2.

              NO>replace with the same spec bulb.                                                                 FR
              2. Check the signal circuit of left reversing lamp.

              a. Ignition switch: LOCK.                                                                           ST
              b. Disconnect the connector H012 of left rear combination lamp.

              c. Ignition switch: ON, place the shift control rod at “reverse gear” position.                     BR
                                                        d.  Measure  the  voltage  between  the  left  rear  combination
                                                        lamp  connector  H012  terminal  5  and  the  ground  with  the   BW
                                                        multimeter in voltage gear.
                                                        Standard voltage:                                         EL

                                                          Multimeter connecting terminal   Standard value

                                                               H012(5)- grounding       Storage battery voltage



              Check if the result is ok?

              Yes>go to Step 3.
              NO>repair or replace the open harness.
              3. Check the earth circuit of reversing lamp.

              a. Ignition switch: LOCK.
              b. Disconnect the connector H012 of left rear combination lamp.

                                                        c.  Use  a  multimeter  to  measure  the  resistance  between  1#
                                                        terminal of left rear combination lamp connector H012 and
                                                        earthing.

                                                        Standard voltage:

                                                           Multimeter connecting terminal   Standard value

                                                                H012(1)- grounding           About 0Ω
