Avalon power windows failure after battery replacement

Hi, I have a 2018 Toyota Avalon hybrid with 102659 km. After replacing the vehicle battery, the power windows can no longer be operated and an error is stored in the error memory. Any ideas?

After replacing the battery in a 2018 Toyota Avalon hybrid, the power windows stopped functioning, and an error was recorded. This issue may be due to the window regulators losing their initialization. A suggested solution is to reset the window regulators by fully lowering and raising the windows while holding the button. If this procedure fails, it may require professional assistance to initialize the regulators, as was ultimately done at a workshop.

Did this summary help you solve your problem?

I had a similar issue with my Toyota Avalon (though not the same year). It sounds like your window regulator lost its initialization. Have you tried resetting the window regulators? Usually, you have to bring the window all the way down, then all the way up and hold the button for a few seconds. Does that do anything?

Thanks for the suggestion. I tried that procedure, but it didn't work. Do I need special tools or software to reset the window regulators?

No special tools should be necessary. However, it sounds like the reset procedure isn't working for you. In that case, there might be a deeper issue with the window motor or the regulator itself. If the usual reset does not work, I suggest you go to a workshop.

Thanks. I took it to a workshop and they initialized the window regulators for 290€. Appreciate the advice.
