Seat belt light

[Fryer]

The seat belt light has suddenly stopped appearing in when I enter the car(Rx450h 2011) and start up. No chimes either if you drive off. Any advice gladly welcomed. Thanks in advance.

With any modern car with multiple ECUs the first step towards diagnosis and repair is a fault code read and then a communications check between the module responsible for the seat belt detection and the sensors involved.

Do you still have warranty through Lexus servicing?

Have you moved the seat position recently?

[Fryer]

Thanks for the reply. I don’t have warranty. Seats are moved only slightly with the memory settings.

Also could I have a Toyota dealership look at this issue ?

They use the same Toyota Techstream diagnostic kit but even though they are both the same company some dealers only accept their brand, if your Toyota dealer is more convenient just give them a ring and see what they say.
