Today when I was coming back from work my power steering just stopped working suddenly. The HICAS light also turned on a few moments later. It is a r32 gtst with a rb25deneo . Checked the fuses and power steering fluid and it all seems fine. I turn the car on and drive for a few seconds before the power steering gives way. So initially the power steering works when I turn on the car.I took it around the block a few times and the hicas light didn't turn on ( was only driving for a couple of minutes at a time). I put on a aftermarket steering wheel on a week ago but never had this problem. What could it be ?

The aftermarket steering wheel is the problem

Unless it accomodates the steering wheel angle sensor the hicas aint gunna like it. .when I got my R32 gtst the hicas light was on ... the(stock) steering wheel had been taken off but when it was put back on the dot on the column and dot on the back of the wheel werent lined up... . Lined them up.. reset ecu, no light

Some race day guys just cancel the power steering. With the old rack. Steering feels like a go cart but its fine, not that much of a difference. No more leak problems and sensor crap anymore.

there is only one way you can put the boss kit on to line it up with the horn clip. I never took the lines off the hicas bar when the changed the diff i only took the two bolts off. Like i said, the when i start it it initally works but then stopped after driving down the street. i might need to do a diagnostic test on my ecu. my mechanic who even put the engine in didnt really have a clue really

OMFG just spent the whole f**king day trying to swap over the pump and guess what...IT DIDNT DO JACK SHIT!!WHAT A WASTE OF 6 HOURS AND $160!!! ANYONE HAVE ANY MORE IDEA'S? I cant be any clearer, it works when i start the car and drive it for 10-20 second...i can turn the car on and leave it on idle forever and the power steering will work...but it stops after driving...the HICAS light comes on after about a minute or 2 when the power steering stops working.

i had enough of these jdm's man...too many headaches and its making my wallet empty!!

Did you do the hicas diag?

alright the HICAS light comes on, then 4 quick flashes before the HICAS light stays back on, then 2 quick flashes then the light stays on, then 1 quick flash before it stays on again. It repeats this and you can hear knocking noises coming from the back of the car.

Unplug the smaller plug from the HICAS computer and see how you go.

alright, i did that, and the power steering worked for a few seconds before shutting off like usual. Could it be that the smaller plug has gone and needs re wiring?

Doubt it's the plug. Take the HICAS computer out and have a look inside, there might be a loose screw or bad solder joints or something. Mine randomly craps out and it's pretty annoying. Makes me wish I bought an R33 GT-R :(.

My car does this some times if I don't warm it up enough. when I come up to a stop the power steering stops, HICAS comes on and it try's to stall and a banging from sound comes from somewhere it's got me f***cked what it is.

i already tried putting in a working hicas comp and the same thing happened. Maybe it's the hicas position sensor behind the steering wheel?

And Dylan, that noise might be the diff because when I do hicas diagnostic the noise comes from the diff Edited by IM-32-FK

i know its got something to do with the speedo because i read it on other forums. Like i said the speedo doesnt work anymore as well. I had to get a custom speed cable because its a neo in a r32. I took the cluster off and the needle behind the speedo wasnt snapped or anything, but i dont how its supposed to operate when its working and when its not. Someone please point me in the right direction

    • I get that taking off the head is best but that's a bit much for "just" valve seals. I was just under the impression that one would be able to rotate to TDC and be able to temporarily drop the valve without losing it and effectively having to remove the head to then recover it. I never knew people actually pushed rope into the cylinder to do valve seals hahaha So just to confirm, just going to TDC will not work? In that case I know when I do valve seals I'll maybe just remove the head and do some other things while I'm there, or just wait until I do an engine build.
    • The old approach was to fill the cylinder/chamber with a length of rope pushed in through the sparkplug hole. The new approach is to connect compressed air to the sparkplug hole and fill it with enough pressure to push the valves up. Doing either of these things with the head on and the engine in the car is a lot less pleasant than doing it properly.
    • Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?
    • One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching
    • Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.
