B1312 on Suzuki

Passenger seat occupant sensing fault, occupancy mat or module (Suzuki)

Severity: Inspect soon

A fault in the passenger occupant sensing leaves the airbag light on, and the owner complaints show an unresolved fault. Honda's and Toyota's owner's manuals say a lit airbag light needs prompt attention because the airbags or belt tensioners may not work as designed.
