ok, start with a n00b question, what does HICAS stand for and what does it control?. Something to do with the steering or 4WD system right!

I asked about this in someone elses thread but noone replied....why does my HICAS light flash on and off randomly and frequently?

I just had new wheels and a wheel alignment done and ever since then its had a problem

always on for a minute or so on start up and then flashes on and off

Grants right. The power steering pump tends to breath a bit out of the top of the reservoir. It doesn't take much loss of fluid to get the light flashing. So have a look & top it right up. Problem should then go away.

If you want a drift look to your engine bay, put a white cotton glove over the top of the reservoir.

also if wheel alignment is out the light will come on

thats what it might be then because when I turn left it comes on and when I am driving straight or turning right it doesn't

but thats only when the car has warmed up tho...

strange :)

isnt it just running a different size tyre on the front and back that drives the hicas crazy on gtrs?

I'll admit i dont know too much about these cars, but i remember reading something in HPI magazine about the light coming on to let you know that the car has activated the HICAS.. definatley could be wrong though since i dont own one :lol:

To clear a few things up:

- HICAS light only comes on when there is a problem with the HICAS system

- Sometimes the light will only come on after a period of time driving as that is when the system detects a fault (eg no speed input)

- Tyre size does not affect HICAS (does affect the ATESSA 4WD system though)

Start with doing the HICAS diagnostics, that should spit out a fault code telling you what the problem is. Do a search for how to do this....

Also do a general search for HICAS - problems with it have been discussed many, many times before....

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
