The B1915 diagnostic trouble code is an indication that the air bag driver circuit has failed.
There are several components that aid in the deployment of the driver side airbag when/if the vehicle is in an accident. The air bag deployment system will not be able to work as intended if one or more of these components are not working properly. When this happens, the air bags will not deploy and the driver and passengers will not be provided protection from the impact of a crash. When the B1915 diagnostic trouble code has been stored and the air bag light is on, this usually indicates that there is a short to battery in the air bag driver circuit. This may also be an indication that there is a short in the clockspring wiring or Air Bag Control Module wiring.
When replacing the clock spring, it is important to make sure that it is not moved from its set position as this may cause the clock spring to become defective. Be sure to inspect the clock spring wiring for damage and corrosion before making your diagnosis. Damage and corrosion in the clock spring wiring is commonly overlooked as the cause of the B1915 diagnostic trouble code. Also be sure to check the air in the steering wheel.
A diagnostic trouble code is normally considered serious when it causes drivability issues or a change in performance. The B1915 diagnostic trouble code will prevent the air bag system from working properly and the air bags will not deploy if the vehicle is involved in an accident. For this reason, the B1915 trouble code is considered serious and extremely dangerous. It should be diagnosed and repaired as soon as possible.
Replace faulty air bag deployment system components.
Replace faulty clock spring.
Replace air bag control module.
The air bag system should be properly disabled prior to completing any repair. If not properly disabled, the air bags may go off and cause serious bodily injury. It is also important to use great care when replacing the clock spring to not move it out of position. This may cause the clock spring to be defective.
