                 Diagnostic steps

                 1 .    Check fuse

                 (a)    Ignition Switch: ON.
                 (b)    Check whether the fuse of fuse box: F11(60A), F36(10A) is fusing or not.
                        Check whether the result is normal?
                                                                                                                     04
                        Yes> go to step 2

                        No> replace fuse

                 2 .    Check mode select switch C039 power supply circuit.

                                                           (a)    Ignition Switch: ON.
                                                           (b)    Disconnect mode select switch connector
                                                                  C039.
                                                           (c)    Use multimeter to measure the voltage
                                                                  between pin 9 of mode select switch C039
                                                                  connector and the ground connection.
                                             C039
                                                            Multimeter connection          Standard value

                                                               C039 (9) - ground            Battery voltage

                 Check whether the result is normal?
                 Yes> go to step 3
                 No> if there is no battery voltage at pin 9 of C039 connector of mode select switch,
                 repair the open circuit between Fuse F36 (10A) and pin 9 of C039 connector of the
                 mode select switch.


                 3 .    Check the power supply ground connection of mode select switch

                                                           (a)    Ignition Switch: OFF.
                                                           (b)    Use multimeter to measure the voltage
                                                                  between pin 8 of C039 connector of mode
                                                                  select switch and the ground connection.

                                                                  Standard electrical resistance (check
                                                                  whether there existent an open circuit)
                                             C039
                                                            Multimeter connection          Standard value

                                                                C039 (8)- ground                ≤ 2 Ω
