           Symptom description:
           A failure happens to the driver SRS, and other SRSs are normal.
           △ PROMPT:
           Take driver SRS as an example, check the driver safety belt pre-tensioner, driver side
           airbag, passenger front airbag, passenger safety belt pre-tensioner, passenger side airbag
           (all have no clock spring) with the same method.


           Diagnosis Procedure

           1.     Check battery voltage


           (a).   Unplug battery positive and negative binding post.


                                                      (b).    Use a multimeter to measure the voltage
                                                              between the battery positive and negative
                                                              electrode.


                                                                Connect the pin by      Standard value
                                                                    multimeter

                                                                   Battery positive
                                                                 electrode - negative      Approx12V
                                                                     electrode


                                                                                                     Page 2062
