Lexus IS Power Windows Not Working After Battery Replacement

Hi, I've got a 2008 Lexus IS with a gasoline engine. After replacing the battery, the power windows stopped working. Now, I get an error code, and I can't operate any of the windows. I suspect the window regulator needs re-initialization. Any ideas?

After replacing the battery in a 2008 Lexus IS, the power windows stopped functioning, and an error code appeared. The issue was suspected to be related to the window regulator needing re-initialization. Attempts to reset the windows manually were unsuccessful, leading to the recommendation of using a diagnostic tool at a workshop to resolve the problem. Ultimately, the window regulator was re-initialized at a shop, successfully fixing the issue.

I had a similar problem with my IS. After replacing the battery, the window controls went haywire. Have you tried the reset procedure?

Reset procedure? Could you elaborate on that? I've tried holding the window switch down, but it didn't seem to work.

Yes, I tried resetting it myself, but it didn't work. It turns out the regulator needs to be initialized with a diagnostic tool. I would advise you to visit a workshop.

Thanks, I appreciate the advice. I ended up taking it to a shop, and they re-initialized the window regulator. Cost me 290€. Problem solved.
