I get a warning after a moment and the power steering gets semi hard. Before the error the power steering is fine. Power steering ABS FIX.
Can someone point me in the right direction?

I found that when I remove the Park ECU plug the error goes away.
But the car drives kind of erratic.
How would you call this wiring harness, if I wanted to purchase a new harness?

Most likely this is going to be the dash harness, but can you let me know which module you are unplugging this from? I am not sure what the park ECU is so do you have a part number or a little more detail as to what this is?

As for this issue, I would suggest we start with checking the codes and finding out what is there.

The fact that the power steering is operating when the light is not on sounds like a control module issue, but we should have some codes that will point us in the right direction.

Just unplugging this module does not mean that this harness or module is the issue so let's start with this info and we can go from there.

Thanks

We need to start with the C codes that you have, and I am attaching the info below on these.

However, based on this info we may have an ABS module issue so let's start with this info and we can go from there.
