Timed out HICAS issue

[Baz]

I've been following this issue on my R32 for sometime now ever since I first got it.

Basically the HICAS light comes on after I travel a certain distance. It has made me wonder because it doesn't come on after a certain period of time but a certain distance everytime after first travelling in my car. Leave it to rest for a while and it resets itself and the same thing will happen again. Also I have no clue about HICAS diagnostics either.

One thing I have found though, is that my HICAS never actually seems to work. And I've never actually had the 4WS kick in on me before. But the thing is that I don't have a locker bar because all the lines still connect into the rear steering rack and there doesn't seem to be any tampering with the HICAS ecu at all.

Is there any dodge way of eliminating the HICAS? Removing fuses? Cutting/crossing wires? Also people with the lock bars, does the HICAS light come on at all times or something similar to my case that after it travels a certain distance the light will come on?

Cheers,

Scott, it would appear that your steering wheel is not centred (I'm guessing an aftermarket wheel) so the HICAS goes into disabled mode after about 6-7km. There is a sensor in the steering wheel to tell the HICAS where it is pointing and if it is not centred/doesn't move when driving it shuts down HICAS.

For more info on HICAS go to the tutorial in my sig.

Yup same thing happens with me hicas light only started coming on when i changed the steering wheel... does this have any long term or major affects?? or is it ok to leave my wheel on

[Jolinator]

it usually means you have the incorrect boss, or your as geoff says, the steering wheel isnt dead center, both are very easy and not time consuming to fix

[froggy]

well my boss kit is the right opne it fits straight on,.,,.. i think its the steering wheel isnt dead centre problem and i need an alignment... so if i just adjust my wheel so its perfect straight this will fidx it>??? i still dont see how just taking the steering wheel off affects the sensor.. damn nissan

I too have the same problem, but not after any set time or distance.

I asked a mechanic who also owns a 32 and he put it down to a dodgy solonoid or to that effect. It started happening to me after about 3 weeks from purchase, since then I have changed my after market wheel twice. Made no diff, will follow this thread with interest, wiered.. :confused:

I too have the same problem, but not after any set time or distance. My handbrake light does the same. Neither everyday, nor at the same time, just every so often. Before you ask, yes my h/brake is all the way down.

you can disable the HICAS by unplugging the KYB motor located in front of the rear steering rack. I would advise against it as it makes steering much heavier. You will know if the 4WS has been working or not because of the difference it will make once you unplug it. The light may stay on constantly though, can't remember.

The problem has been covered a hunred times

Your problem is likely to be:

a) A lack of powersteering fluid.

B) An incorrect boss kit.

c) An incorrectly fitted boss kit.

Just because the boss fits, doesn't mean its the correct one. You need a boss with holes for the HICAS lugs offset at about 2AM and 8PM: see this tread:

I also had an issue with the piping on the powersteering resevoir coming loose. I pulled the hoses up as high as possible (which was bloody hard) and then replaced the standard clamps with ring clamps.
