ABS and STC warning lights

I have a 1999 S80. The ABS and STC light comes on every few days. If you shut the engine off and restart they go away. Any ideas?

If problem with sensor then light is permanent.

If connector is bad or wire is broken inside harness but still touching then you get intermittent light coming on which is alleviated when you switch off engine. When engine starts computer senses everything ok. After warming up and or hitting some bumps connection is broken and light comes out. History repeats itself. This problem is common in the 850/s70 series.
