    Got local Toyota to perform ECU flash as per TSB 0036-19 and it solved the problem on my 2019 Tundra. Finally towed today with no problems confirming it works in my case.

    I gather some dealers couldn't figure it out but it does exist and it did work in my case.

    See attached and show service department if they can't figure it out.

    Good luck!
