Hello everyone, I have 2019 ES350 Ultra Luxury, whenever I turn my car on the RCD OFF light flashes only once in the instrument cluster. during the service time, I spoke with the technician and he said it is normal that the system is working properly

and I never saw this in any other ES350 Ultra Luxury

and then in the NHTSA manufacturer communications section, there was a communication and I don't know if this is applicable to my situation
