The B1930 trouble code indicates that a shorted circuit has been detected in relation to the airbag deployment system's safing sensor.
The B1930 trouble code is intended as a failsafe to keep the crash sensor from deploying the airbag without due cause. A shorted circuit for the safing sensor occurs when the circuit is flooded with too much energy. The resulting damage will disable the safing sensor and trigger a stored code in the vehicle's onboard computer.
Faulty or damaged electrical wiring is the most common cause of a B1930 trouble code. The safing sensor charging system may be overworking itself. A faulty safing sensor is another possible cause of a B1930 code.
A malfunctioning safing sensor will disable activation of the airbag. However, if short circuit problems are affecting the vehicle’s airbag system as well, the lack of a safing sensor failsafe may result in a deployed airbag. A stored trouble code and illuminated engine lamp will also accompany a B1930 trouble code as diagnostic indicators.
A B1930 code may be first verified by testing the vehicle with an ODB-II code reader. All wiring relating to the safing sensor and airbag deployment system should be checked out for potential signs of damage, including (but not limited to) corrosion, disconnection, misplacement and faultiness. If the wiring checks out properly, the safing sensor itself should be looked over for potential signs it may be malfunctioning.
Body-related trouble codes can refer to different things depending on the model of vehicle. It is important to verify that this particular code description pertains to your vehicle. Refer to the vehicle manual if you are unsure.
A B1930 trouble code will typically disable the airbag deployment system, as a working safing sensor is necessary to activate it. Although this will not affect the vehicle's drivability, it may host a safety concern in the event of a crash. Should you choose to drive a vehicle with a disabled airbag deployment system, make sure to use other safety features, such as a seatbelt.
Replace any fried electrical wiring and mend any poor connections in the circuit as needed. If the safing sensor or other components related to the circuit have been damaged, they should be repaired or replaced accordingly. If the charging system overpowered the circuit as a result of a fault, it should be replaced. After all repairs have been completed, retest the vehicle to see if the trouble code recurs. This will indicate whether or not the repairs have proved successful.
In most cases, the safing sensor can be found behind the kick panel on the passenger’s side of the vehicle. The safing sensor is located on the passenger’s side in order to make it more susceptible to the force of a crash impact.
