              Diagnosis procedure
              1. Check the bulb of front left turn signal lamp.                                                   AX

              a. Check whether the turn signal lamp or hazard warning lamp connector in front left combination lamp gets
              loose or falls off.                                                                                 FR

              b. Dismantle the turn signal lamp or hazard warning lamp bulb in front left combination lamp.
                                                        c. The positive and negative poles of bulb are connected to   ST
                                                        the  positive  and  negative  poles  of  battery  respectively.
                                                        Check if the bulb can be on.
                                                                                                                  BR

              Check if the result is ok?

              Yes>go to Step 2.
              NO>replace with the same spec bulb
              2. Check the wire harness and connector between front left turn signal lamp and body controller.

              a. Ignition switch: LOCK.

              b. Disconnect the connector B004 of left front steering lamp

              c. Disconnect the connector B061 of body controller

                                                        d. Use a multimeter to respectively measure the resistance of

                                                        7# terminals of left front steering lamp connector B004 and
                                                        10# terminals of body controller connector B061.
                                                        Standard resistance:
                                                         Multimeter connecting terminal   Standard value

                                                               B004(7)-B061(10)             About 0Ω




              Check if the result is ok?
              Yes>go to Step 3.
              NO>repair or replace the open harness.
