My hicas light has started to come on after a bit of driving too. I've just put on an aftermarket steering wheel, but the bloke said that it should be ok.

I've checked the fluid level and it is all good, so i would have to guess that it is the steering wheel.

Anyone know a good place to go to get a boss kit for a momo steering wheel that doesn't screw around with hicas?

I am having problems with my hicas... After about 15 - 20 minutes of driving, the light comes on. There's no noticable changes to the way the car drives, and I can see the rear wheels move ever so slightly while steering to full lock. The first thing I did was to top up the power steering.

I have been trying to get the diagnostics to appear, with no luck. Either I'm doing it wrong, or there's something wrong with a sensor like brakes or speed, etc... So just to verify my procedure:

1) Turn off car, leave in neutral

2) Turn it on

3) 20o left and right 5 times.

4) Pump brake 5 times

5) Press brake again

6) Drive (or roll, really) 5 metres ahead really slow.

1) From the time I turn on the car, to the time I start the 5m drive, how many seconds do I have?

2) In step 5, do I hold the brake in slightly and heel-toe it foward, or tap it in and out?

My car is a stock R33 '95 model. The 4WS appears to be fully electric.

i used to have this prob - just went away about a yr ago by itself.

whenever it came on, i just pulled over and restarted car... gone for another couple of weeks.

the only time it would come on for me was when doing long straight stretches of road that required next to no steering.

i used to drive a same long stretch of road frequently - 7 out of 10 times the hicas light would come on... ALWAYS at the same spot give or take 100m

im dont understand what you mean here? if you are saying your rear wheels move when you are not in diagnostic mode just sitting on the spot and you turn your wheel you are wrong!

Skyline 4ws only opreates when you are travelling and not stationary unless you are in diagnostic mode!

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
