3 Amigos but only while parking

I have now fixed the power-steering pump which was leaking, but I had to replace the belt as a clever PO fitted one that was 1cm too small so it was a PITA to fit and ended up de-laminating.

Now a new problem has presented itself. When I reverse park into a space at work I get the Three Amigos come on. ABS TC and a another warning.

Could this just be a case of taking the truck out for a clean at the local foreign-worker wash? or Do I need to remove the wheels and clean the sensors?

The lights go off once I get up to road speed.

Did a search but not much about it only happening at slow speeds. Customer of mine had a reader thingy so cleared all the issues. Will see if it returns. Might just give it a clean.
