Hicas ===> Not again... :(

[Gav]

Bugger - new boss kit fitted but still light comes on and the odd unexpected steering input.

Old "dog chewed" steering wheel is going back on for comparo. testing this weekend.

Re: the Mines computer - well it was an unexpected find that I came across when fitting a new stereo.

I know for sure that it has removed speed cut, probably boost cut and rev limit increased also.

The fuel map is probably altered as it runs pretty rich (puff on black smoke on full throttle - flames from zaust on quick throttle off!).

Have a PFC on the way over from Japan and will compare before dyno readings before and after.

Without it car are hard to drive while stay with it car give you more trouble.

After disabling the hicas on my R33 the car is EASIER to drive if anything and it is definitely a lot more predictable and easier to control when the back steps out.

I have an even stranger hicas problem.

Sometimes when driving and I come to a stop (like at the lights or in a traffic jam), then press the accelerator, I lose power steering for quarter of a second and the hicas light flashes quickly.

This ussualy only happens in the rain, or just after it rains.

I know there is a tiny leak in my boot, but I don't think it is letting water under the parcel shelf.

i hav a r32 and ever since i bought the car the hicas has been on constantly but i hav never felt the effects of loss of power steering.

does anyone know y my hicas light stays on?

[BOoStEr]

When I started my R32 after a week it seemed to crank against some extra load.When it started there was a loud belt scream and the hicas light was on. After about 30 seconds the noise stopped and light went out. Maybe power steer pump was siezed or perhaps a valve or something was stuck in that complicated looking hydraulic gear near the rhs chassis rail. Any ideas?

I've got a R31 GTS-R and it has HICAS too.

What OIL is recommended ?

Is there a specific Brand to put in there... ?

My light flashes on and off as i go over bumps so that's just a case of a little low on the oil ?

[Doctor]

Any type of power steering/auto tranny fluid is ok to use.

[R31Nismoid]

Is it ok to mix types?

Or are P/S all the same

Cause i know that oils are all different grades and stuff.

Should i flush it out maybe?

If i do have to flush it... how ?

(i've got no idea with cars)

Sorry i need some help here. I am guessing when it rains water is getting into one of the sesors (or the HICAS comp). Has anyone heard of this before, or know where I should check for water leaking in?

Thanks.

Greg.

Greg , unless you have a water leak in the middle of the rear parcel tray , then the puter will be fine.

As I said before , when the problem occurs , dive under the said rear tray and check the code flashes on the bottom or side of the box. Should be a little opening somewhere with a red LED.

Get the number and I will check the manual.

There is something like 20 or 30 different things it could be , so getting the code is going to narrow it down.

Cheers

Thanks Ken I will try that.

I tried the Hicas Diag mode, I can seen to decript the flashes tho.

Thanks,

Greg.
