❗[Help] Seat Belt Warning Not Working – 2008 Corolla (JDM)

Hi all, I have a 2008 Toyota Corolla 1.6L (Made in Japan) and the seat belt warning doesn’t work — no chime, no light.

•	Door switch works (dome light, key chime okay)
•	Found grey plug under seat and matching white connector
•	“B ON / B OFF” doesn’t show in cluster
•	Everything else in the cluster works normally

Is this feature missing on JDM models? Or could it be disabled or unplugged?

Appreciate any advice — thanks!
