WELL!!!!!!!!!!!!!!!!
Checked fluid . Cleaned all connections.NO CHANGE. Called TOYOTA who told my brake pads were low so they would reshod them.They were only done 2k miles ago. And have those squeal tabs fitted anyway not electrical ones.
Although I have the Toyota electrical manual for the car and I thought I had traced out the circuit fully . I was employed in medical electronics. But there in all the leads was another wire sneaking off to a blocking diode which then ended up at "stop light system"
I had a DUFF STOP LIGHT. This brings on my dash indicator to CHECK BRAKE FLUID LEVEL according to user manual.
My user manual does not mention this at all. And even gives the wrong replacement bulb type in its listing. So there you go.
Its fixed now.
Thank you for the replies.
