Warning lights on dashboard

[petrolhead239]

My 2006 GS300 recently had a Battery changed after standing for some months. Upon being driven, the tyre pressure warning lit up. After setting tyre pressures it remained on and then was followed by vsc, brakes, engine etc. The runs and drives perfectly with no faults ~ how do I turn off the warning lights?

It should  reset its self but you may need techstream but try taking off Petrol cap and reseating it those lights do come on when petrol cap seal goes.

i had a 55 gs300 and that did that on regular basis i changed the petrol filler cap and it never did it again

If the warning lights don’t go off after 3 trips then you have a current fault. You need to get the errors code from a fault reader to understand the problem as there are hundreds of reasons why the warning light can come on.

Thanks guys, I've never heard of changing a fuel cap, but because they're pressure sensitive, maybe it makes sense. The filler cap on my Toyota C-HR is identical, so I've just swapped them over. I'm going to be amazed and overjoyed if this works. The systems have been checked and there are no faults at all. Hence It's been a mystery.

Wish me luck, and thanks

That is obviously untrue, otherwise the lights wouldn't be on as they signify a fault. Needs a better code reader to be used, one that can read all the systems rather than just standard engine codes.

Sorry to whoever just called me a liar! Tell it to the extremely well equipped diagnostic specialist who not only checked out the codes, but also spent time physically checking the systems. I find this kind of comment both counter-productive and personally insulting!

Well then someone is lying to you if you believe that to be true. 

The lights only turn on at all when the computer generates an error code. 
No error code, no lights.

So if the guy told you there are no codes, he's either incompetent or lying to you. 

The only other realistic possibilities are a complete computer communications failure which would result in no display on the dash at all or everything lit up on the dash + no speedo e.t.c. or a dash failure which should have a lot of other noticeable consequences.

You know what I find counter-productive and personally insulting?
People twisting what other people said. Colin never said you were lying, he said it was untrue that there were no faults. He even explained WHY.

Get a code reader that reads all faults instead of just engine codes and you'll have your answer.
