Lexus IS airbag warning light

My 2023 Lexus IS with a gasoline engine is showing an SRS airbag warning lamp in the speedometer. I've run diagnostics and the code points to a possible defective cable or plug connection somewhere in the airbag system. Mileage is currently at 85977 km. Anyone else seen this?

I had a similar issue with my IS. Have you checked the connections under the seats? Those are often the culprit due to movement and potential interference.

Thanks for the quick reply. Which connection specifically were you referring to? The one for the seatbelt pretensioner, or further back towards the airbag ECU?

Yes, it was indeed the seatbelt pretensioner connection under the driver's seat. Ultimately, I'd recommend taking it to a trusted workshop, but checking those connections first could save you some diagnostic time.

Appreciate the advice. It was indeed a loose pretensioner connection as you suggested. The workshop charged 95€ to diagnose and fix the loose cable. Thanks again!
