What it means
Common causes are a loose/corroded connector, damaged wiring, or a failed sensor. This is a Kawasaki DFI (Digital Fuel Injection) service code, read through the FI light or the bike’s service/diagnostic mode. It applies to Kawasaki FI models such as the Ninja, Z, Versys, and ZX range. Note: Kawasaki service-code numbers can vary by model — confirm against your manual. After the fault is repaired the code is kept as a stored "history" code; clear it through Kawasaki’s service/diagnostic mode.

Frequently asked questions
Will code 15 stop the bike?
Rarely — the ECU falls back to a default value, so it usually still runs. Fix it to keep fuelling right across altitudes.
