Warning light in the speedometer of the 2007 Toyota Highlander petrol engine: System readiness check possibly not completed

Hi guys, I have a problem with my 2007 Toyota Highlander gasoline engine. I am concerned about a warning light in the speedometer. I think the system readiness check may not have been completed, but I'm unsure. Have any of you had anything like this before and can give me any tips as to what the problem might be? How did they solve it at the garage and what was your experience? I would be grateful for any tips!

Hey, I had a similar problem with my 2005 Toyota Rav4. I only have some experience with cars, so I'm not really an expert. But it actually worked fine at my garage. They said the battery was recently disconnected or replaced, which was the cause of my warning light. It cost me 90 euros to fix the problem. What battery do you have in your car and when was the last time it was changed? That way I might be able to help you a little more.

Thanks for the tip! My battery was last replaced at my service with 35011 KM. I think that was only a few months ago. But that would make sense that the warning light comes on because of the battery. I'll have it checked at the garage. How long did the repair take you?

Hey, I'm glad I could help! For me, the whole thing took about two hours. They had to do some tests and then the indicator light had to be reset. With waiting time and everything, I was at the garage for about half a day. Keep me posted, I hope it's nothing worse! Good luck!

Thanks for the info! I was hoping it would be quicker, but if it helps, I'll take my time. I'll drop by the garage tomorrow and let you know what I find out. Many thanks for your help and support! I also hope it's nothing worse. Keep your fingers crossed for me! See you then!
