                                                        between No. 2  terminal of B001 and B072 and  grounding
                                                        respectively.                                             FR
                                                        Standard voltage:

                                                          Multimeter connecting terminal   Standard value         ST

                                                               B001(2)-grounding       Storage battery voltage
                                                                                                                  BR

              Check if the result is ok?                                                                          BW
              Yes>go to Step 6.
              NO>repair or replace the harness                                                                    EL

              6. Check the front fog lamp ground circuit

              a. Ignition switch:LOCK.
              b. Disconnect the connector B001 of left front fog lamp
              c. Disconnect the connector B072 of right front fog lamp

                                                        d. Take a multimeter to measure resistance between No. 1
                                                        terminal of B001 and B072 and grounding.
                                                        Standard resistance:

                                                          Multimeter connecting terminal   Standard value

                                                               B001(1)-grounding            About 0Ω

                                                               B072(1)-grounding            About 0Ω




              Check if the result is ok?
              Yes> retest the above steps

              NO>repair or replace the harness
