B1650 on Toyota
Occupant detection/classification system malfunction (Subaru, Toyota)
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. Subaru and Toyota tie B1650 to the system that decides whether the passenger airbag deploys.
This page covers only what differs on Toyota. For what B1650 means, the ranked causes and the test order, see the B1650 guide.
