B1922 code definition

A B1922 trouble code indicates a circuit failure in the passenger side's airbag deployment system.

What the B1922 code means

The driver and passenger airbags are governed by independent circuits. A B1922 code indicates that the circuit for the passenger airbag system is incomplete. If the airbag electronic controller unit (ECU) detects an incomplete circuit, a B1922 code will be stored on the vehicle's computer.

What causes the B1922 code?

An incomplete circuit is most often caused by issues with the electrical wiring. Corroded, disconnected, damaged and otherwise broken wiring will sever the circuit. Faulty components, such as a malfunctioning ECU or sensor, may also be to blame for a B1922 issue.

What are the symptoms of the B1922 code?

If the passenger airbag's related circuit is incomplete, the passenger airbag will not deploy, even if the appropriate impact criteria are met. In addition, a stored B1922 trouble code and illuminated engine lamp will be present for the sake of diagnosing the issue.

How does a mechanic diagnose the B1922 code?

The B1922 code may be first diagnosed by reading the vehicle's onboard computer with an OBD-II code scanner. All wiring related to the passenger airbag circuit should be examined for possible signs of wear or damage. A voltmeter or Autohex device may be used to troubleshoot the source of the circuit break more easily. Any components relating to the passenger airbag, such as the airbag ECU, should be tested for potential signs of faultiness.

Common mistakes when diagnosing the B1922 code

Body-related trouble codes often describe a number of different problems depending on the specific make and model. Make sure you're interpreting the code correctly before proceeding. Check with the vehicle user manual if you're unsure.

How serious is the B1922 code?

If your vehicle is subject to a B1922 code, the passenger airbag should be considered inoperable. This should be considered as a safety hazard to anyone driving on the passenger's side. Although it isn't a threat to the vehicle's drivability, a B1922 should be addressed promptly if the vehicle regularly carries passengers.

What repairs can fix the B1922 code?

The wiring related to the passenger airbag circuit should be checked, repaired or even replaced if necessary. Components in the airbag deployment system (including the ECU) should be checked for signs of malfunction and repaired accordingly. Following any repairs made to address the B1922 code, the vehicle should be retested in order to verify whether the problem has been solved for good.

Additional comments for consideration regarding the B1922 code

In many vehicles, airbag-related circuitry can be found on the passenger's side behind the kick panel. Refer to your vehicle's user manual for specific instructions on where and how to access the airbag system circuits.
