Here are all the customization options available with VXDIAG VCX NANO Toyota Techstream 16.00.017 on a Toyota GR Yaris. All models will have the same options but with empty menus for unavailable items like the Slide Roof, Seat etc.
Techstream version example: 16.00.017 (better version, some reported cannot see customization menu on V17 and onwards version)
You are able to make lane-change indicators flash 4 times instead of 3, enable the auto windows up & down from key fob and lock turn, and disable ESE, disable door warning, disable tail remind buzzer, remove seat belt warning and more.
can’t see anywhere to enable auto door locking when starting or driving off because Auto door locking isn’t on the GR Yaris.
The utility function can also act a bit like a ‘customisation’. Like turning on the mileage to oil change on start up and AWD mode etc.
