Hicas Problem

[JordansR32]

Since doing my engine conversion I pulled all my hicas out and put a lock bar in, changed the pump to a rb25 pump, made sure all the system is bleed, and the steering seems heavy still. Now I do plan to put a non hicas subframe in with all new arms and stuff just havtnt done it yet.

I don't know if its something I have missed but do u have to do something with the hicas ecu in the boot like cut and join to wires to trick it?

If anyone can helpt that would be good, sick of semi heavy steering haha

There is a solenoid as part of the steering lines, on the pressure one. Some guys remove and blank it off, but I would think running a 12v ignition fed to it would be easier.

On the actually pump itself?

no on the line

Courtesy of my Neo transplant (and non-HICAS subframe) I deleted everything to do with HICAS, except the HICAS computer and the sensor on the rack. The PS in my car is exactly as it has always been - ie it works properly.

The only unusual thing about my setup is that I disconnected the smaller of the 2 plugs on the HICAS computer. This was in fact done 14 years ago when I first got the car because the HICAS was crook anyway. It's all it takes to disable it on an R32. It may be necessary for you to keep the HICAS computer hooked up to the larger plug.

Well yer thats what I did to my car, pulled all the lines out to the rear of car, pulled solenoid out everything. Swapped pump to a 33 pump with just the one port coming off it, Just didn't have time to do the subframe, so lock bar so time being it was. I havnt actually checked the rear plugs, don't think I have undone anything back there.

Is there any plugs that plug into the power steering rack itself fort the hicas I can't even remember if there was.

Solenoid is on the rack.

Hmm interesting never knew this helped, will give it a go

[JordansR32]

Tried blocking off the solenoid on back of the rack didnt work at all, just blew oil out the bottom of bracket. Does anyone have any other sugestions? Like any wires that need to be earthed out or at the ecu?

And also the solenoid on the rack with the 2 wires coming out of it with the plug on it what does that have to plug into, mines not plugged in, thinking thats causing the dramas to?

Well...it plugs into the matching plug on the driver's side engine bay loom.
