Master caution plus
Tried to start our 2019 ES350 this morning and the battery was almost dead. The lights on the panel dimmed out and flickered. Put the charger on it and got it running but now the Master Caution is flashing and there are 2 error messages. OBD shows no faults. Any ideas?

So what's the fix? Take it to the dealer? Local dealer wanted $250 to diagnose, then there is no telling how much the repair might be. The service writer hinted that the ECU might need to be changed..... Seems like the dealer could "reset" it without too much problem.

When my battery won't start my car, I always take it out and charge it outside the car...slow trickle, plus check water level. You may want to disconnect the battery overnight to see if it clears your codes/messages, and also get a battery hydrometer to see if you have a dead cell...assuming you aren't looking at replacing the original battery.
Unless the service writer thought you fried the ECU by charging the battery in car, I'd avoid that dealer like the plague. $250 to diagnose your initial dead battery, or to read the error messages? That's pretty steep.
It may also take two trips/cycles to clear the codes/messages you created with the dead battery.
Good luck.

Have you driven it to see if that would turn off the warning light? When I replaced the battery in my wife's RX, I had some caution lights illuminated - they told me to drive a few miles and they would go out. They were right.

There is a way to reset rear camera detection. There was discussion about it recently.

Winner winner chicken dinner! The YT video you suggested did not work, but looking at several videos I got er done. For those that care, on the 2019 ES350 you have to go into the service menu: With the car running you hold the menu button by the touch screen and turn the lights on and off 3 times. Then you chose the Function setting, then the camera setting. You arrow down with the back or return button next to the menu button. You choose the greyed out setting button and hold your finger on the touch pad for 3 seconds. That take you to the menu where you can memorize the center and angle settings. Center the steering wheel and select the center setting. Now you turn the wheel all the way to the left, then all the way to the right. Center the wheel and select the Angle button. Turn the car off and then restart it and all is good!
