Hey guys I have a question about the HICAS system. Well like most of you I stored my car for the winter and just today when I was getting it ready for winter I found that my rear HICAS lines were leaking. I knew they were bad and needed to be replaced but just glad it happened now. So my issue is Remove it or repair it? I’m sure you all heard this before and the most common answer is Remove it.
The deal is I love the turning radius the HICAS gives me and on the track if I want to grip I want the HICAS system to help out. However when I decide to drift I want 2 wheel steering. Both Repairing and removing will cost around the same (Repair will be a little more) but there is fare more work involved with removing it.
I read something that said that the HICAS has a fail safe mode that will automatically switch the cars wheels to 2 wheel steering if there is an issue. Is this true? And if so can I somehow modify the HICAS so that at a flick of a switch I send the HICAS into Safe Mode? Essentially having 2 wheel or 4 wheel steering option right at your finger tips. If I can get any info about the HICAS that would be great. I know only what the manual gives me.
If this isn’t possible I will remove it. Because the system is heavy. So removing it will give me less weight and a simpler car.
i haven’t tried, but i imagine you could easily do it by putting a switch in the wiring to the control box on the passenger frame rail in the engine bay.
I was actually having the same discussion about this with a friend a week or so ago.
I also think its possible to wire a switch to the power or control box that activates it, OR since its leaking, why not put in SUPER HICAS? some that come on R32s have a switch for 4 and 2 wheel steering modes.
if I’m not mistaken it is the SUPER HICAS in the 92 wasn’t it? Well the deal is i don’t think you want to shut off the box because the box I believe scenes if there is an issue with the system then it activates the fail safe mode that locks the wheels into a foreword position.
However if you were to hook a switch up to the steering position sensor to cause it to work and fail on command. That should cause the SUPER HICAS system to go in and out of safe mode. Plus the steering position sensor sits right beside the steering wheel so its an easy wiring job as long as you know what your doing that is. As well i believe there is a fuse or a relay in the fuse box next to the battery that could also be simply pulled out if you want 2 wheel steering or put back in when you want 4. Not sure what kind of side effects it might have though doing this kinda stuff to the car.
The other question is why would you need a HICAS stabilizing kit if this works and its free and stupidly easy.
Yeah I know I do need to look into it more. It is just that it’s hard to find people that know anything at all about HICAS. Hell even the people at NISSAN have little or no clue about it.
Well HICAS was apart of a long list of Nissan cars and trucks. They SHOULD know all about it. I was really hoping someone on this website would know quite a bit about this too. Maybe I should just have it fixed then mess with it on my own.
