B1448 on Kia
Front passenger seat occupant sensor mat fault (Kia)
Severity: Inspect soon
The airbag light means the system has found a fault, and Honda and Toyota owner's manuals say to have it checked promptly because the airbags may not work as designed; Kia ties this code to the sensor that decides whether the passenger airbag should deploy.
This page covers only what differs on Kia. For what B1448 means, the ranked causes and the test order, see the B1448 guide.
