Abs, esp and check engine light just turned on.

Hi all, i cant seem to find info anywhere on whats goin on. I bought a ma xr5t couple months back and it is a great car and we love it. There are a few issues i have found but generally cosmetic so it didnt really bother me. We Thought we would really put it through its paces by doing a great ocean road trip from adelaide. All running smoothly till we were returning home and adelaide side of tailem bend the abs and esp light turn on. I looked through the manual and said abs had stopped working and same the esp. Which is strange as the both went at same time? Im pretty handy and would like to repair it myself. This morning we went to go for a drive and the check engine light is now on? Which is strange as its full of oil its not knocking and there are no strange noises. So im starting to think its a sensor or elec glitch in the matrix. If any one has any idea could they please let me know
