Hey AKHTAR RAZA KHAN,

You have replaced the PCM and under hood fuse box which has fixed the non start issue?
Was it a PCM issue or the fuse board causing the non start?

Now is the only fault code for communication with the EPS?
Does the EPS work, do you have power steering?

If you have no power steering and there is only an EPS communication code I would start by checking the fuse and then the power/grounds to the EPS module.

Regards, Joe

Hello,

It sounded like he EPS control unit is out and not communicating, but to be sure we can run a CAN scan to confirm the failure. Here is a video that shows you how with steering wiring diagrams and EPS control location so you can see how the system works:

If the control unit is bad you will need to have it programmed.

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
