I've just encountered a similar problem to this with my S2. Power steering seems to be heavier than normal but it's a constant not intermittent problem. HICAS is plugged in and no lock bar or dash lights. I'm going to check fluids soon but I'm guessing it's a pump issue or the speed sensor?

Check your fluids first there should be a light on your dash unless the globe has already been taken out. Has your car got an aftermarket steering wheel? By memory my was low fluid or the pump

Ah OK, no my steering wheel is a tired looking stock one haha, no dash light on when car is running but I'll check the fluids when I get some daylight tomorrow, otherwise I'm guessing its the pump on its last legs :(

Its strange because I had aftermarket steering wheel on my car and the hicas light would come on when id go over 100kph roughly and didnt go out till I turnd the car off then once I put the bar in the light was on all the time when I put the bar in I also put coilovers tie rods lower control arms ect so it went straight on a tow truck to pedders and the aligned it all for me and they fould the no power steer problem and they told me it was the pump or electrical I drove around for a couple days before I checked the fluid to find it was bone dry I topped it up had power steering again but driving it with no fluid must had wrecked the pump so when I changed it everything was fine just the hicas light and when I put the gtr dash in I just took the globe out im not sure if having a microtech or any aftermarket computer makes a differance

Hey guys new to forum and I was just curios due to my car has a lock out bar (not lock out kit) and my car still has hicas ecu plugged in and all I have done also is remove dash bulb and still retain factory sexy and I have never had an issue and have never had to do what blk94r33 did to fix he's issue, but in saying this my mates 33 power steering pump works on start up but stops working when you start to drive, he has lock out bar and ecu is still plugged in but has this power steering issue

Any advice will be very great full and both cars are S1 33 sedans

Does both you and your friends car have abs? Because the hicas ecus are different apparently and that may be why. Also does your friends car rev slightly when turning the wheel when stopped? Because if so it could be the speed sensor for the power steering, its working when stopped but not when moving? I am an amateur myself so I am just spit balling here, perhaps the experts on here can shed some light.

Hey dude both our cars are series 1 which don't have abs, andim not sure if it revs higher when u turn steering wheel, and speed sensor what does this have to do with power steering issues, but I was told by him that he's speedo has stopped working and at same time that's when he realised power steering was not working, but I've read up and not really finding anything about speedo affecting the power steering due to the power steering lines have one solenoid which is controlled via hicas ecu and as I said all my loom n hicas ecu is plugged in and works mint no steering problems and he's is same yet steering issues could it be he's speedo is f**ked and if yes please explain as to in like confused to y it would

My best guess is something to do with the busted speedo, as I've read on these forums that the sensor which controls how stiff the power steering is at which speed, is usually to blame for a problem like that, especially seeing as it works to begin with but soon stops once you start driving. I reckon fixing the speedo will fix the power steering too. Good luck!

Sorry to bring this alive again but THANK YOU SO MUCH SEVERE!!!
Joined up to SAU just to say thanks you to severr33
This solved my 12 month problem of no power steering. Tried so many other things (besides Hicas Ecu replacement)
But now that ive done this i can rule out the Hicas ECU. Solder those wires back together and try order one somewhere and hopefully it will fix it.
My forearms thank you again.

Hi all i tried the method of connecting pin 5 to pin 14 by simply unplugging the HICAS ecu, then getting a small wire and bridging those 2 sockets on the plug.

To my surprise it actually turned on my ignition and dash as if i had turned my key to 'accesories'. (my key was NOT in the car)

I started the car and the power steering was uneffected by this method.

Is the pin relating to the power steering solenoid in a different hole?

14 months on still functioning 100% and i've had no problems with any steering components.

Hi Paul, reviving an old thread here (hopefully).

Just wanted to check in and see if after all this time if you still never had any issues with the steering?

On a side note, does anyone know which pin is the speed input into the HICAS ECU?
According to the wiring diagram for the HICAS ECU, pin I see that pin 12 says "Engine Speed" and pin 31 goes to the "ECM", 'Data link connector" and "Vehicle speed signal (in meter)", but I'm not sure which is the input.

    • Yeah, the latter. No diff should have a centre replaced without checking clearances because its unlikely to be the same as whatever came out. Not that that stops most people just checking a new centre in
    • Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?
    • in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.
    • I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.  
    • If they just called it the "Mazda Tiffany", it would have been spot on.
