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

  • 5 weeks later...

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?

so far i havnt even noticed a difference in the steering with the lockbar.

No noticeable change in heavyness at low speeds etc etc so couldnt comment. Im taking it to the track on tuesday. 1st trackday without it so ill let you know if it was much different to with it in.

Daily driving tho.. hasnt seemed to effect much

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!!

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
