              3. Check the left front light adjusting motor ground harness

              a. Ignition switch:LOCK.                                                                            EG
              b. Disconnect left front light adjusting motor connector B004.
                                                                                                                  TR
                                                        c.  Take  a  multimeter  resistance  gear  to  measure  the

                                                        resistance  between  the  No.  4  terminal  of  left  front  light
                                                        adjusting motor connector B004 and grounding.             AX
                                                        Standard resistance:

                                                          Multimeter connecting terminal   Standard value         FR

                                                               B004(4)-grounding            About 0Ω
                                                                                                                  ST


              Check if the result is ok?                                                                          BR
              Yes>go to Step 4.

              No> Repair or replace the left front light adjusting motor ground harness.                          BW
              4. Check the left front light adjusting motor

              a. Ignition switch:LOCK.                                                                            EL
              b. Disconnect the connector B004 of left front light adjusting motor

              c. The No.6 and No.4 terminals of left front light adjusting motor are respectively connected to the positive
              and negative terminals of the battery, and then a variable voltage signal (less than the battery voltage) can be
              added to No.5 terminal of the light adjusting motor to observe whether the left front light adjusting motor
              is working normally

              Check if the result is ok?

              Yes>go to Step 5.

              No> Repair or replace the front left light adjusting motor.

              5. Check headlight adjustment switch

              a. Replace the same specifications and models of headlight adjustment switch, and observe if the headlight

              height adjustment is working properly.

              Check if the result is ok?

              Yes> Replace headlight adjustment switch.

              NO>retest the above steps
