This problem is driving me insane, especially since i have a track day tomorrow.
Where to start..
I removed the hicas a few years ago, no problems there kept the ecu in the boot, even the abs one to be sure.
Recently i have gutted, stripped the weight and here it comes, cut out alot of wiring..
Now i didnt touch anything that i thought would be related to the hicas but alas as soon as i hit about 50-60k's my steering goes into limp mode
I tried disconnecting the smaller plug on the back of the hicas ecu and that makes no difference, if i unplug the bigger one on the right the power steering is heavy as soon as i start it.
I have spent hours reading most of the threads going back to 02 and everyone seems to have a different fix and thats fair enough because there is alot of things that can go wrong with hicas.
Today i fitted the hicas globe back and tried to get it into diagnositc mode, either im hopeless at it or perhaps due to a lack of sensors its not reading that im trying to get it into that mode.
Checked all connectors in the engine bay seems fine, everything plugging into the back of the cluster is fine
Even wired the rear abs sensor back in with no luck
Only thing in the back of my mind was a metal ring i tossed behind the new steering wheel i fitted, but i dont think that is part of the steering sensor at all, its wasnt under the 19mm nut that holds your steering wheel on.
Im now reading wiring diagrams from meggalas site but they arent the best quality
Im now thinking about fitting a non hicas rack and maybe a r33 power steering pump but there is not alot of info out there...
