By now, you’re likely aware of the features that can be customized on your Highlander via the infotainment system (if not, see your owner’s manual for details). These include a variety of climate and light-related settings, the behavior of your door locks, the height of your liftgate, etc.
But did you know that there are a variety of “secret” settings related to your power windows, moon roof, turn signals, etc. that can only be customized by your dealer? Or by you, if you have access to the right software.
Want to roll the windows down with your remote? Customize the number of flashes when tapping the turn signal? The default is three flashes, but you can set it to five or seven flashes. Etc., etc., etc. Well…
If you take your Highlander to your dealer’s service department, they can plug a diagnostic cable into the OBD2 port, fire up a piece of software called Techstream, and tweak the settings to your liking.
Hopefully they won’t charge you for this service, at least not for initial setup, but… They might. The good news is that you can skip the dealership, as well as any potential fees, by buying your very own copy of the Techstream software, along with the necessary Mini VCI cable.
Where to buy Techstream?
Believe it or not, you can find copies of Techstream + the required cable on Amazon for less than $30 total w/free shipping. That price is so low that I question the legality of the copies that they’re selling, but…
I know of several Highlander owners who have picked up their own copies (and cables) from Amazon and freed themselves from having to rely on the dealership to customize their vehicle’s settings.
What about you? Have you visited the dealer to have any of these “secret” settings changed? Or have you used Techstream to do it yourself? In either case, please share your experience in the comments.
