The hicas light stays on occasionally, after i start the car. If I turn the car off and on again, it goes away.

It's happened maybe 6 times now, in the last 3 weeks.

It never comes on after start up, while driving.

When its on, theres no issue with steering etc. Car drives normally. So i'm guessing some sort of wiring fault with the light, or a switch?

Any tips or known issues to look for here?

The power steering fluid was on the low mark when i checked, so i topped it up, but that wasnt it.

My hicas is intact, and i have no issue with it. So the lock bar suggestion isnt what i'm looking for.

cheers

ive tried getting into hicas diag mode. no luck.

can someone spell out the procedure for me?

this is what i tried.

start engine

turn wheel left then right 20deg 5 times (i tried 6 times too)

press brake pedal 5 times (tried 6 times too)

then i read somewhere, a faulty steering posiition sensor will prevent entering diag mode

if i have the procedure correct, i need some info on the steering position sensor. ie. how to get to it, and remove/replace, or test.

if i have the procedure wrong, slap me, and show me the way

cheers

the day i removed my hicas was NOT a day i look back fondly upon!

make sure you have a good couple of hours... its kinda tricky to get happening the first time

Dont listen to him :) It is a simple job and if your on a hoist will take about 40-50 mins max. And i even had to drop the rear muffler to get at one side.

Use the guide on SAU and its a piece of piss. Even easier if you have a mate helping.

I had this same problem, I ended up ditching hicas but before I did I found that just disconnecting, cleaning and replugging in ALL the wiring plugs to do with steering and hicas stopped it from happening. I couldnt trace it to just one connection.

i've read conflicting reports on r33 lockbar installs.

what i want to know is....

does it affect the progressive power steering? i.e. does your steering still remain lighter at low speeds, firmer at higher speeds?

or is that lost, and you get heavier steering all time when you fit a lockbar

edit: is the steering position sensor used for anything besides hicas? does it need to work?

Yup yup. Leave the computer where it is and just remove the globe.

The track (just got home) was amazing.

I wish id put the lock bar in sooner. Coming out of corners a bit quick and having the ass step out is so much more controllable! I was just stomping on it in 3rd and "power sliding" haha. With the Hicas i was getting thrown all over the place.

I got a couple of vids of some minor skids ill link when theyre uploaded. But the best ones were at the end of the track that there was nowhere to video from :huh:

So, go DO IT DO IT!!

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
