Auto Lights

[MattB]

Hi

Have Is200 53 plate, the auto light function seems less sensitive on this car to my last Is200.

I think it is possible to adjust, prob via laptop and obd.

Dealers want £50 to plug in the computer......nice.

so questions......

1. Can you buy lead and software to run on laptop (did this once for audi using Vag-Com)

2. What software and lead work.

3. Can the lights be adjusted.

Any help would be great

thanks matt

The only answer I can give is yes it can be adjusted, mine was adjusted by the dealer on my IS200. I had to provide the instructions and they insisted on asking Lexus GB for permission first !!

It used the Lexus Diagostic tester:
