Defect
The driver's seat belt warning system contains an alert switch inside the buckle that was improperly assembled. Repeated buckling and unbuckling causes abnormal wear on the switch contacts, allowing wear debris to accumulate between them. This debris creates a short circuit across the contacts, which may prevent the warning from canceling even when the seat belt is correctly fastened.
Corrective action
Inspect the buckle on all vehicles. If the condition is confirmed, replace the alert switch inside the buckle or replace the buckle assembly with a corrected part.

状況
運転者席シートベルトの非装着時警報装置において、バックル内の警報スイッチ接点の組付けが不適切なため、シートベルト脱着の繰返しにより接点が異常摩耗して、接点間に摩耗粉が堆積することがある。そのため、接点間が短絡し、シートベルトを正しく装着した場合でも警報が解除されないおそれがある。
改善措置
全車両、バックルを点検し、該当する場合はバックル内の警報スイッチまたはバックルを良品と交換する。
