I recently purchased my first gtr (very very very happy) on the dash the "HICAS" light is illuminated when driving, i received no manual with my car. does this mean that the four wheel steer fluid needs toping up or ???? if so where would i purchase such fluid etc ??? please help cheers guys look forward to meeting some of you guys.

Hey GTRIIN,

OK - I'll post a serious answer for you - I hope

The HICAS is the four wheel steer - and as far as I know - if the light is on, your 4WS will be off line.

If you have a non-std steering wheel, without a proper 4WS boss kit (which has a 4WS sensor in it apparently) - that will cause this problem. I thought this only happened after exceeding 80klms / hr (which is when the HICAS actually starts to work). So if it's on ALL THE TIME - this may not be your problem.

If you are low on steering fluids - this will cause the HICAS light to come on. If your light is on all the time - this seems like a good place to start.

Lastly, this seems to be a common problem with the older GTRs (I have an '89 R32 GTR BTW). HICAS seems to be more trouble than it's worth. Long term you may want to look at a getting a HICAS locking kit installed, and then just pull the HICAS bulb from behind the dash.

my 2c worth :(

my 89 gtr drives fine for a couple mins, then the steering goes heavy, then the hicas light comes on further down the road, i had a feeling this is too do with the ecu so im borrowing the ecu from a GTSt today to see if it remedies the problem, if it does i will try write up a 'how to stop a damaged ecu guide' as the ecu physically looks fine inside, other than that i may have to remove the hicas, something i dont really want too do

woot woot!

sucsess.

Vehicle: R32 GTR

Problem: After a minute or two the steering becomes heavy, soon followed by the HICAS light illuminating on the dash cluster.

My Solution: HICAS ECU is kaput! This can be located in the boot on the drivers side under the parcel shelf.

How to test yours: Under the parcel shelf three 10mm head bolts hold in the ECU, undo these then unclip the ECU, replace with one from a car with working HICAS. For my test I used the HICAS ECU from a R32 GTSt, worked excellently, only took 5 mins to d the swap and back, and probably about 10 minutes driving it.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel

      What should I do next to hold the head on

      By MBS206 · Posted

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
