r33 4wsteer not working on hoist @60kph

[skylite]

just wondering if the 4 w steering should work when the car is doing over 60kmph on the hoist. i suspect my car done a bit of drifting in japan, is there a fuse to disable the 4w steering that may have been taken out.

i think you'll find the hicas only works after 80kmh

[Duncan]

and only a degree or 3, pretty hard to see with the naked eye?

[skylite]

just have to go a bit quicker than 80 and getsome one to watch the rack ends. thats when i get another turbo. and get licence back. anyone know of any big turbo kits available without the fitment fuss of a new exhaust manifold or not wortha fortune.

cheers dave

search the forums for instructions to perform the hicas diagnostics.

with the diagnostics you'll see exactly how much the wheels move etc. (not much)

more like a twitch

this is what all the information states however I disagree.

I believe it comes on as low as 35-40km .

It doesn't come on at low speed to help you park???

:confused:

2 years ago i was having major problems with my hicas..... noone could figure out what was happening not the mechanics... not the nissan hicas test software not nothing.... the light always used to come on when doing low speeds...

the reason why it was coming on was because small fragments from the broken horn button had found they're way into the path of the steering angle sensor. I could make the hicas light come on when doing U turns, when going around corners really on cue....

When taking these corners these bits of plastic moved infront of the sensor blocking the information the sensor need to adjust the rear wheels so hence the light came.

question: If hicas only works at speeds above 80km/h why was my light coming on? I wasnt taking these corners/ u turns at 80km and above...... If it does only work 80 and above there would be no need for the sensor to try and read the angle of my steering wheel.

my conclusion: IT OPERATES BELOW 80km/h

once I found the bits of plastic and removed them I never had a problem again. Everything else was working fine as the entire car was tested using a hicas/ nissan computer in bayswater.

and no I dont park at 35-40kmp/h.

I am speaking from personal experience not from what I have read.

No. It's not like the Honda system.

The light does not indicate that the HICAS system is operating, only that there is some malfunction. In your case, from a sensor malfunction.

I am confused why did you write this?... isnt this what I was saying :confused:

[ylwgtr2]

i think what he is trying to say is that light came on below 80klms because you had a fault in the system not because it was working and had a fault....

[akeenan]

the only fault was that the steering angle sensor couldnt communicate with the angle of my wheel....

but why should it be doing this if i wasnt going above 80km/h..... there was no major fault as it was plugged into hiocas test equipment.

[Elithrar]

It most likely communicates all the time, processing information from the rear wheels; whether it is actually perfoming an adjustment at the time is irrelevant.

[ylwgtr2]

why should an ABS light come on all the time when the ABS module fails....after all the ABS does work all the time does it?

[akeenan]

2 rather interesting points here.

[FATGTS-R]

I have HICAS on my R31 GTS-R.

It definately works at low sped as I tested with the car stationary. Parked next to a wall and chocked a thin piece of wood to just sit there between the tyre and wall. Turn the wheel and it fell down. About the 60 or 80 km/h thing I was told that the wheels turn in the opposite direction to low speeds. Mine turned the same way the fronts did when stationary but at higher speeds could not tell.

[crooser]

one thing hicas wont do is give you a greater turning circle.

the rear is supposed to steer the same direction as the fronts. this is to help drive the a$$ around to reduce oversteer.

It is a warning light (like all the others in the dash). It is not an "ABS in use" light.

It's not like the "slip" light fitted to some.

Apparently the 4WS system only works from 0-60 km/h. This is what i have been told where as the mazda system like on the mx turbo mazda works all the time. Not 100% sure though just what ive been told...
