Had a moment a few days ago where a parking brake yellow warning light came on and said need to apply footbrake for calibrations. Did it and it went away.

Week later and now my EPB isn’t working and I can only put the car into park? The amber warning light comes on. Also I noticed that for some reason I can’t use my cruise control now as well as it just says cruise not available so I assume skmehow is also linked to the EPB! Before I send it into the garage is there any test or fix I can do myself?
