The B1914 diagnostic trouble code is an indication that there is a short to ground in the air bag crash sensor #1 or the air bag crash sensor #2.
The air bag system uses sensors to indicate when it is necessary to deploy the air bags if the vehicle is in a crash. If the air bag crash sensor has received a short to ground signal in the seat belt assembly circuit for at least 0.5 seconds, information about this error will be sent to the Air Bag Control Module. The B1914 diagnostic trouble code will then be stored and the check engine light will come on.
The most commonly made mistake when diagnosing the B1914 diagnostic trouble code is neglecting to check the seat belt assembly circuit properly. Other mistakes that are commonly made are overlooking faulty wiring and not taking the time to follow the diagnostic steps properly.
A diagnostic trouble code is usually considered serious when it causes driveability issues or a change in performance. The B1914 diagnostic trouble code is serious because if this trouble code is stored in the Air Bag Control Module and the air bag light is on, the entire air bag system will be disabled. The air bags will not be deployed if the event that the vehicle is in a serious accident. For this reason, the B1914 diagnostic trouble code should be diagnosed and repaired as soon as possible.
