Heavy steering + HICAS faults

[dojobi]

Hi all,

I've been having this problem for about 6 months now, but I've been too lazy to fix it.

Basically I've got incredibly heavy steering - almost like I've got no power steering - and when I turn the steering wheel slowly, the revs don't rise like they used to. The fluid levels are fine, so it's not that. I had Mark at Hills hook it up to his little diagnostic machine and he said some sensor for the steering was screwed and not sensing properly (possbily on the steering rack? I can't remember). Does anyone know what this sensor is? This all seemed to happen when my wiring burnt out and I had to get it replaced (the guy in Japan did the DODGIEST wiring on his gauges).

I've also got error codes 22 and 32 for my HICAS which is kind of bad too I'm sure. I'd also like to get rid of that. Anyone know? I read a thread a while back that said if some wire from the speedo to somewhere else was missing, then the HICAS would give error codes. Does anyone know about this either?

Sorry for all the questions

Cheers,

Michael

Damn. I'd swear I put this in the maintenance section. Sorry admins.

Anyone? Any help would be appreciated.

Even if you've had a seemingly unrelated problem with steering/HICAS, I'd like to know about it so I can at least get an understanding of what kind of things go wrong with the steering.

slack how no body replies....

Yeah I think I might go and post it at SDU. There seems to be more general knowledge about this kind of stuff over there. It's probably because the Kiwis have a bigger and older Skyline scene than us.

Well I'm not replying cos I have no idea what is wrong.. but now I guess I've replied ?!

have u checked all the steering components out? like the steering rack and arms. get it checked out at a suspension specialist like whiteline, they might be able to spot the problem youre having.

hope that helps

his happened to mine after a dodgy alarm install, get an auto elctrician to check the wiring behind the dash, it can become loose and if a wire opens up through wear etc, it can cause a relay fault and you loose power steering

[dojobi]

Yeah I'm pretty sure it's a wiring problem, as I had the whole thing rewired when it burnt out. The thing is though, when the steering wheel is turned hard, power steering kicks in. This would mean the right wire is attached. It makes it a bitch to drive in relatively smooth curves in the road as I can't always tell when the power steering will kick in.

Randy, I haven't checked it out as I thought someone here might have been able to just say "it's the XX sensor on your steering rack". I might have to take it in to a place like Whiteline if I can't resolve it myself.

Has anyone looked at their steering rack? Are there any sensors on it at all?

Cheers,

Michael

The hicas steering wheel angle sensor is in ya steering wheel, well, just behind it... check that out first...

[dojobi]

Thanks, I'll have a look there.

i had a similar problem while driving my r33 gts-t...

we were going around a corner at slow speed, and for some reason, the steering went incredibly heavy, like the power steering had cut-out and the HICAS warning like came on...

As to why this came on, i don't know... any help would be greatly appreciated!
