My HICAS light keeps coming on after about 15 minutes of normal, straight highway driving.

I had the rear HICAS bar replaced as it was bent, but the light still appears. The steering feels ok, but is a little notchy when you turn the wheel either way.

Im going to take it to Wilkinsons the next time Im in Perth, but in the meantime, anyone got an idea what it may be, or experienced similar?

Dude the light comes on when the power steering fluid becomes low as well.......

Check that before spending any money man

seen the same when a boss kit wasnt fitted properly - I know your case is different, but you did ask :)

Lock your hicas, the car will handle better, you get the added bonus of weight reduction and you can just remove the light bulb from the days. I did this, much better to drive, never looked back.

rossco,

One of the joys (not) of an 89 GT-R is the randomness of warning lights. Check your power steering fluid levels (top it right up anyway). Also when the warning light comes on, go and have a look at the module in the boot. With the engine on there should be a flashing light. It will flash anything up to twenty something times & then briefly pause. Count the number of flashes & compare with the diagnostics in the manual. I will try & dig the page out if you don't have it. Usually turning the car off/on again makes the light go away.

:(

I have this problem too. Mine only comes on when im driving on the highway. From what i have been told it can b anything from the non standard steering wheel or HICAS capable boss kit to air bubbles in the hoses. I dont know if the air bubbles in the hoses is true but thats what i was told. I know a few people who have skylines and their lights come on too. Mine has no change in driving when the light comes on so im not gonna stress about it.

Mine has started to play up again :O, it was ok for a while after instlling spacers but now the light is back on again.

jaygtr, they run hydrolically and can only be stopped with a HICAS lock kit or HICAS removal bar.

If i fit the lock kit will it stop the knocking coming from the hicas motor?

After-market steering wheels can also cause hicas issues. The stock steering wheel holds the steering sensor in proper place. I've heard that there are boss kits that cater for hicas (someone please confirm this, i'm looking for it as well). If the sensor is off alignment, it tries to calibrate for roughly 10 mins and when it cant it gives up and fires the warning lamp.

When you start to get notchy feedback and all of that, bar that baby up. not worth the dollars to troubleshoot.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      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.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      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)?
