Most modern vehicles are equipped with a supplemental restraint system (SRS), which is also known as airbag passive restraints. This system supplements the seat belts during a collision to protect the front seat occupants from serious injury.
The SRS relies on sensors to send signals to the control module that a collision is severe enough to deploy the airbags. If a problem with one of the sensors occurs, on-board diagnostics will log a B0092 code.
What Does the B0092 Code Mean?
Diagnostic trouble code (DTC) B0092 stands for “Left Side Restraints Sensor.”
The SRS is composed of sensors, an airbag module, a clock spring wire coil in the steering column, a control module, and wiring and connectors.
For the airbags to deploy upon frontal impact within 30 degrees of the center, several sensors must be able to send signals to the SRS control module. Some of these sensors include crash sensors, safing sensors, and occupant weight sensors.
SRS sensors act like switches that complete an electrical circuit when activated. The SRS normally self-tests every time the ignition key is in the ON position, activating the airbag light for about six seconds.
However, if the powertrain control module (PCM) is unable to get the necessary input from one of the sensors, it will log code B0092.
Note: The definition of code B0092 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
What are the Common Causes of the B0092 Code?
- Faulty SRS sensor
- Control module issues
- Faulty wiring

How to Diagnose the B0092 Code
While DTC B0092 is a generic powertrain code, keep in mind that its steps for diagnosis and repair can vary from one vehicle to another. Diagnosing this trouble code typically involves using items like a scan tool, digital multimeter, airbag system tester, and vehicle-specific test harness, among others.
If you’re not familiar with the mechanics of using these tools, it might be best to have a certified mechanic diagnose your vehicle instead. But if you’ve had your fair share of diagnosing trouble codes, then you can go ahead and do it yourself.
How to Fix the B0092 Code
Attempting to fix a B0092 code can be tricky, especially if you don’t have the right tools and technical knowledge. Under these circumstances, it might be best to bring your vehicle to the nearest auto repair shop and have a trained professional perform the necessary steps to fix the issue.
But if you think you can do the job on your own, make sure to have the right equipment and guides before starting. Guides like those from Chilton or an ALLDATA subscription contain vehicle-specific repair information, which can be handy when repairing trouble codes like B0092.
