The B1917 diagnostic trouble code is an indication that the air bag memory clear circuit has failed.
The air bag control module is separate from the powertrain control module (PCM). When there is a problem with the air bag system, a fault code is stored in the air bag control module, instead of the powertrain control module (PCM). Once a diagnosis and repair is completed for the stored fault code, this code can be cleared from the air bag control module using the proper scan tool. The air bag memory clear circuit is the component of the air bag system that allows diagnostic trouble codes to be cleared from the air bag control module. Following repair, if the original diagnostic trouble code is unable to be cleared from the air bag control module, this is an indication that there is a problem with the air bag memory clear circuit and it has failed. When this happens, the B1917 diagnostic trouble code will be stored in the air bag control module and the air bag light will come on.

The most commonly made mistake when diagnosing the B1917 diagnostic trouble code is failing to inspect all of the necessary components. It is important to inspect the fuses for the air bag system, the instrument cluster, and the wiring harness. Make sure there are no blown fuses, faults, or damaged wiring.
A diagnostic trouble code is normally considered serious when it causes driveability issues or a change in performance. When there is a problem with the air bag system, it is considered serious because it is possible that the air bag system will be disabled completely. This can prove dangerous if the vehicle is in an accident and the air bags do not deploy. For this reason, the B1917 diagnostic trouble code should be diagnosed and repaired as soon as possible.
