    Mine turns off in the rain. I think that’s common as the radar doesn’t work with rain. Mine always comes back on though on its own.

    Had a 2.5" level kit put on along with wheels and tires today. Now dealing with all these lights on. Front is little higher than rear but I've never had them come on when I pulled it up on my ramps and started it. Why would all these lights be on?

    Mine does the exact same thing. I had a 2018 Camry rental with the TSS and it did the same thing turned off in rain and turned back on...seems to be a generic issue with TSS And rain.

    My 2018 Tundra has not done this since the update. Did it once but some fool changed 2 lanes and cut right in front of me and the system worked correctly.

    My wife’s 2019 Honda Pilot does it like 2-3 times a week. Super annoying..

    This is scary . I have a 2020 SR5 and want to level it and put a trd pro gille on it but think I might have to wait a bit . I have 2217 miles and no issues thus far.

    I’ve got a post recall sensor on my all stock 2019 and just tonight in rain had a sensor malfunction error. Seems to be rain related

    the sensor will turn off in bad weather. It states all of this in the manual.

    18’ with 6112/5160. Never an issue since day 1.

    haha. It’s a radar. If there is too much “noise” while driving, ie, heavy rain, snow, etc. The sensor will turn itself off since it cannot get a good read from the sonar. Albeit you shouldn’t be relying on the TSS in bad weather anyway.

    Makes sense, but the PCS off warning on the dash is annoying.

    And to think anyone would rely solely on TSS to prevent crashes is idiotic. I can see the lawsuit now blaming the PCS for rear ending somebody: “but the PCS sensor failed! That’s why I crashed into him!”
