Having posted this in one community I realised Renntech being referenced a lot in my research so I figured it would be worth raising my question here.  I also appreciate that ICARSOFT is a very low end scan tool however I do think it is telling us some good information.


The car is failing to connect with some of the front electronics, most notably the power steering, front windscreen wiper, headlines/aux lights, starter relay.  Then I noticed if I use the jump points in the engine bay she comes to life.  The power steering does not seem to work at all though.


Further research shows all these components have a common ground located near the jump points (GP-15).  So, I was just really wondering if anyone knows of any 'weak points' in the system in the front left of the engine bay?   The car has evidently taken a big knock to the front left wheel and I am suspecting dislodged something. 

During my diagnosis I figured I would ping all the systems, and this is what I have found:
