B1916 shows up on Nissan and Infiniti as an airbag circuit fault, commonly described as a short on the driver airbag side. The exact wording varies by model and year, so this is one to read carefully.
B1916 is a Nissan and Infiniti SRS code that points at a problem in an airbag circuit, most often reported as a short, frequently on the driver airbag loop. A short can connect the circuit to power or ground where it should not, and the module flags it because it cannot trust that circuit to fire correctly in a crash.
One honest caveat: B1916 is less consistently documented than the big crash-data codes, and its precise definition can shift between Nissan platforms and model years. [VERIFY exact circuit and short type against the specific Nissan or Infiniti model and year service data before condemning a part.] Treat the general meaning here as a starting point and confirm the specifics against the service data for your vehicle.
It reads as a circuit fault, which is a live hardware problem. A short gets repaired at the wiring, the connector, or the component causing it, and the code clears once the circuit reads right. The most common culprits on a driver airbag circuit are the clock spring and the harness, so those are worth inspecting before anyone assumes the module is bad.
Not on its own. B1916 looks like a live circuit fault, so the short gets fixed at the wiring first and then the code clears. If B1916 turns out to be paired with stored crash data from a prior event, our airbag module reset handles that part. Send us the module and the code set and we will help you sort out what is actually wrong.

Inspect the driver airbag circuit, the clock spring, and the connectors for a short or corrosion. Repair the circuit, then clear codes and run the SRS self-test. If you want a second set of eyes on the module or the code set, reach out. Related codes: B1015 (diagnosis sensor unit), B1620 (module internal fault), and B1000 (airbag ECU malfunction).
