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?

A 2023 Lexus IS displayed an SRS airbag warning light, with diagnostics indicating a potential issue with a cable or plug connection in the airbag system. A similar experience suggested checking the seatbelt pretensioner connection under the driver's seat, which was found to be loose. Fixing this connection resolved the warning light issue, saving further diagnostic time and cost.

Did this summary help you solve your problem?

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!
