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

      Thanks for all the replies fellas. Gonna finish putting it back together and see how it handles the set up. If it starts pinging it’ll be parked.

      J50 clock date suddenly reset to January 1

      Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).

      I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating.

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
