Connect with the corresponding interface, use the diagnostic instrument to connect the fault diagnosis interface, and read a lot of fault codes, mainly: the resistance of the driver's side airbag detonator is too large or too small: the resistance of the passenger's side airbag detonator is too large or too small: The resistance of the driver's side airbag detonation device is too large or too small: the resistance of the passenger's side airbag detonation device is too large or too small: the driver's side collision sensor circuit is open or short-circuited.
