What is All Wheel Steering? Does the Skyline have it? | Rob Dahm

[@UhgeneIgnorian]

"steering is pretty straight forward" and left and right

[@schwabentutorials]

pretty straight forward... except wenn you are turning..

[@claudedottin1312]

Uhgene Ignorian you totally turned me straight

[@justmechanicthings]

really set the record straight with that comment

[@itsalic]

Rob at high speed (60mph +) the Z and the GTR change the direction the wheel turns, so if you turn left the rear wheel also turns left. Imagine a high speed lane change it keeps stability rather than pushing the back end wide. Low speeds it turns the other way to turn harder without losing grip. The GTR system is more complicated than the simple system on the Z :)

I was just answering his question so people can know

[@Gridnack]

It's called HICAS (High Capacity Active Steering) and upgraded to a SUPER HICAS system it was available on the Nissans of the late 80s and early 90s. what Rob filmed was sidewall deflection, look closer and the entire sidewall of the tire moves to the inside. I think the hicas system on his is bypassed. plug in the car and put it in diagnostic mode

[@g35tho11]

TheGridnack I got an 06 g35 coupe 6MT and it has hicas .but every time I turn the key switch to “ON” the HICAS component rattles and the two axles going to each side seems to go in and out and makes car slightly shake . What could this be ? Is something wrong ? SHould I stop driving it . I have no check engine light . Please help. I have video of it but won’t let me upload

I also notice once the car is warm and say I go somewhere and park it then go and turn it on it only vibrates for like half a second .. the dashboard light for the HICAS system isn’t ON .

Not Stupid a lot of the world think skylines are amazing too not just Americans

[@schwabentutorials]

Not Stupid, I wouldn't say that, skylines are rare in the rest of the world too, and they are great cars. At least in their time when new they were. Powerful and with a lot of little back then mechanical features to keep traction. Obviosly nowadays there are tons of cars with those features and tons of cars with more power.. And now as they are that expensive if you go for power and features only there are better choices.. Still, the Skyline is a legend.

[@christianrichardson3824]

If you turn steering wheel left to right 90 degrees each direction 5 times then hit brake 5 times it should enter hicas diagnostics mode and you can see rear wheels turning while parked 😁

In my opinion 5:32 looked like the tire was just deforming. When I watch the rim while cornering, doesn't look like it steers at all. (maybe it just steers so little that its difficult to notice?)

[@Trades46]

The R32 has HICAS, something Nissan put in almost all their sports cars in the late 80s up to early 2000s. Though later R33 & later had Super HICAS which went from an oil actuator to electric. Strangely the R35 removed this feature...even though the current Infiniti Q70 still has it.

Looks very similar to my 3000GT VR4's AWS. Funny thing tho... the spare wheel looks exactly the same in design to the 18" VR4 spare. It totally feels like the rear is sliding INTO the turn when it activates... works but feels odd, like driving a forklift with RWS.

[@383mazda]

Galant VR4 had 4WS that only worked above 30mph, and turned with the front wheels up to 1.5°. It felt weird, and most people deleted it due to leakage, inoperability, or cause it felt scary. I think there's a reason most OEM's try rear steer for a year or two then stop - it might took great on paper, but IRL maybe not so much, just like the early 90's automatic door tracking seat belts...

[@ponchodutch]

Your a good bloke now, seeing you can speak Australian and drive on the correct side of the car. Cheers mate. 👍🏼.

[@crxdelsolsir]

Super Hicas is an electronic version of the Hicas that is controlled by electric motors or servos rather than being hydraulically controlled. Honda was first with this set up on the Prelude before the Nissan. Honda's system was actually superior but was over looked due to racers placing more emphasis on Turbo and power rather than control.

[@jaconessjaconess7834]

thank you

[@fabulousprofound]

the few people i know with this did the HICAS delete because it tends to leak like a sieve depending on mileage/age

[@CKilger12]

[@oooLASTODSTooo]

fabulousprofound hicas is also aids. Have had it kick in going around a sweeping corner and almost throw me off the road in a couple of different r32's. Throw it in the bin.

[@mareksumguy1887]

LOL!... that means its MALFUNCTIONING. A properly working system will not do that. Its a form of traction control (VSC). If you like to go sideways and maintain a slide.... you get rid of it.

[@boosted_l6787]

If the steering wheel has been removed it spazzes out the system and needs to be reset, it usually happens about 80kph too

[@TempoMontages]

i did that on my 3000gt vr4 i tried to patch it but it was impossible so you have to buy a aws delete thing

[@MrMichaelBrotherston]

i have a 300zx with hicas,, works great

[@phreakyeggz]

Easiest way to see if your car has HICAS is look for the rear steering rack lmao. On the 300zx HICAS only works at 55+MPH on turn in. There is a diagnostic mode to make it work while park

[@JimmyLLL]

In the R33 the back wheels turn in the opposite direction at slower speeds (like in your vid) and kind of rotate the car but at higher speeds they can also point the same direction and crab across a lane. Would be god to set up the camera again and see what happens.

[@Snoo42]

A pool of information as always rob ❤️

[@kyleramsumair1678]

Bro this is really detailed I must say its good for research

[@AlexSchwartzATV]

I wonder how the 4w steering on the Aventador S compares to the old system of HICAS.

[@torquesteer4594]

That is very cool, how close is this to the SH-AWD that acura uses in the TL?

[@sausagedog52]

last time I tried the same thing with an r33 gts25t it worked while stationary, I do hear that it goes in an opposite direction to the front below 60kph and the same way for changing lanes, etc above that speed

[@DSHanska]

At higher speeds it's supposed to turn towards where you are steering. Cornering hard left it turns the rear wheels left to hold the car in neutral steering insted of oversteer or understeer. Could you make a video of this also? Becouse this is what I have been told by the japanese masters of Tsukuba in some random Option videos :D

[@samson_BNR32]

correct me if im wrong, the r34 back wheels do turn most of the time?

[@purplesalad]

So at highway speeds, do the rear wheels turn in the same direction as the front wheels? I think BMW has it where in parking lots you can have sharp turns, but on a highway you can merge lanes more smoothly.

[@FasterthaMyou]

Teach it, Rob! Never knew it, learned something new.

[@theranter]

If it's anything like the 4 wheel steering that was found on the 3rd generation Honda Prelude, then all you had to do to get the rear wheels to turn was start the car and turn the steering wheel while the engine was running. A friend of mine had a 3rd gen prelude, and that's all he had to do to show that it had 4 wheel steering. Considering that the 3rd gen Prelude was the first car to have 4 wheel steering, and the R32 came out in roughly the same time period, I wouldn't be surprised if the R32's 4WS system was similar to that of the 3rd gen Prelude.

[@kenkozawa9810]

most english is words -rob dahm

[@FroztiProductions]

I heard with super hicas the rear turns outward in slow parking lot turns to give you better angle but turn inward (towards inside of turn) to correct tail in high speed turns.

[@DESUDESU24]

From what little knowledge I know about the HICAS system, there is a way to put it in diagnostic mode where it gets input from the steering wheel. How to do that, I don't know. I could also be severely mixing up HICAS and Super HICAS.

[@malekzain13]

Awesome video as always, one question do you own the gtr? I'm new here

[@anguscopland7422]

Ive had a r32 gts t type m for about 8 years . I notice when u drive on the highway after 10 mins the hicas light comes on, I thought that this was a problem but apparently it indicates the car has stopped the four wheel steering for highway driving..

[@The_JDM_Dynasty]

Time to pull that Dahm hicas system out of your GT-R!

[@strongfp]

It's called the HICAS system... took me about ten minutes to find the feature back in 08 when I first got my Skyline. Wasn't hard to find out like a needle in a hay stack. Most Skylines, and pretty much any Nissan performance car made in the R32 era had it. But majority of Skylines that come over tho have is disabled / removed. since they were either A) Drift cars, or B) Toy cars taken to the track. The system would take quite the beating and the foot work would break, or cause issues, hence the removal. I had a sedan, and it was still enabled. Although, didn't really notice it making a difference really. I guess I wasn't going fast around corners enough.

[@karigreyd2808]

Way ahead of its time

[@l.pmedia]

Only problem with the HICAS steering in the 32's is that it often will fail causing the rear of the car to steer at seemingly random times and has caused accidents previously. That's why so many people to HICAS deletes in them

[@epoxeclipse]

Rob are you sure its not the same setup as the VR4 that activates at a certain mph? the VR4 kicks in at 30mph if I am not mistaken. Same type of hydraulic power rear steering. You can stick a vr4 on blocks and watch it kick in via mph.

[@blahblah-js5ux]

thanks for posting.

[@colindavis5250]

great video Rob

[@Antmattroman]

Is it just inertia driven? Like i remember reading somewhere that i think it was old vws that had inertia driven back wheels that turned when the car was thrown in a corner

[@valcone42487]

correct me if i'm wrong, but I don't believe you need to loose traction for it to work. also, at low speed it is against the way you are turning decreasing your turning radius, and at speed on the highway it will be with the direction you're turning for a faster lane change. unless the high speed is only on the super hicas, i'm not sure about that.

[@josbanse]

You probably should know but I guess the video title would suck if it was: Skyline all wheel steering explained, or would it? A quick info about how HICAS actually works. The system activates when you are going around 80km/h or faster. It turns the rear wheels to the same direction as the front so if you turn left, the rear of the car tries to take itself closer to the corner which prevents oversteering and makes the car feel snappier/quicker on the corners when you maintain traction. In detail level the system might have a bit more to it when initiating turn or if the car detects some movements but that's basically it. The car fights oversteering by holding the rear in the corners. If you raise the car with lift so that the wheels spin freely and give it gas you can film how it works and there already is youtube videos about it. I owned a gt-r and now an R32 sedan with HICAS also.

[@aigo44]

Rob i have a 97 prelude which has an active all wheel stearing set up and it is active as soon as the car is in gear, however it has a actually stearing rack in the rear of the car and the steering angle is more about 10 degrees it looks insane and people constantly freak out thinking my cars broke

[@seanharrison6162]

Watching this and seeing Rob now is so weird from talking about gtrs to making his own rotaries

[@JackastDrift]

there is a self diagnosis for the HICAS with the R33 GTR. turn on the engine, turn the steering wheel 5 times left and right (left-right-left-right-le...), then push the brakes 5 times, HICAS lamp starts blinking, another one on the breaks to activate blink code diagnostic, then about 5-6m very slowly forward, brake... and the rear begins to wiggle :> i don't know if that works with the bnr32, because its HICAS is hydraulic and the bcnr33 has super HICAS (electric).

[@HunterDugasVideos]

Fine. I'll order a damn shirt. I can't afford gas right now but that shirt is absolutely worth it. 😂

[@unknown_user283]

Is it not because the engine was off, there was no oil pressure to move the rear rack?

[@alessiocarlevaro6934]

In the slow mo it looks more like the tyre stretching under load rather than the wheel turning. Try the same turn in the same way but put the camera on the front side of the tyre facing backwards. If the tyre still goes in it's tyre stretch if it goes out it's steering.

[@viktorkaevski3228]

God dahm you're good at explaining

[@Lolfnatic1]

If I'm not mistaken Matt Farrah had a r32 as well and he did mention something about rear-wheel steering in one of his The Smoking Tire. Would be cool to see both of you share some info and maybe drive some cars just saying.

[@LukeTehGamer1]

[@That_NJ_guy]

Kenyon Goetsch Well I never drove one but my parents had two from the early to mid 80s. My mom loved them because they were very controllable cars. My dad liked them but loved his Toyota Cressida. He said his Toyota was crap in snow but for the mid 80s the car was loaded with modern equipment. My parents weren't car people so all the cars were automatic but they were pretty cool. I was young when they still had these cars in the early 2000s. My mom for her first prelude stolen and destroyed the transmission in her second prelude. The cressida was also stolen. 80s cars were strong but so easy to steal.

[@SI0AX]

Now if you look at the front side of the rear wheel, you'll see that wheel itself doesn't change its angle. The side mowement showed on this footage it's the tire mowing sideways because that's what flexible tires do. And you also can see it on the front side of the wheel
