Hicas Lights Coming On Alot

[wokburner]

Howdy lads,

need some advice, I have a 94 R32 GTR and the HICAS lights keep coming on. Its seems to be coming on once I get up to speed and not when travelling slowly as should this system in normal operation. We have checked all the fluids etc in the 4ws etc and it only happened after my mate gave it a bit of a kaning the other day befoer that no problems. Any advice on what to check or how if there is any way to reset the system.

thanksMB

My R32 Gtst does the same thing, I've checked the fluid level and everything, but once i get up over about 120-150kph, the hicas light comes on. I'm not really sure what is causing it, and from the looks of things, it's just annoying, and not affecting anything.

Of course you do that speed on private roads wink wink. But yeah, you tried running the HICAS diagnostics yet?

Of course on private roads! How do I run the diagnostics on this system?

Thanks MB

If you have an aftermarket steering wheel and the sensors arnt lined up perfectly it will cause the light to come on. My gtst does it too.

Pretty sure its the standard wheel, well the one it came from japan with, but will check that.

I have a 32 gtr and the hicas light always comes on after about 10 mins of driving. Previously had a 31 gtst and the same thing happened. Apparently it is a very common fault. Tried numerous fault finding techniques over the years to fix, without success. Now I just live with it!

Cheers

Mine was comin on every now and then.. Had my car data streamed and it turned out to be a power issue with my hicas module. The data stream is not expensive either 100bucks and I also got my ecu reset (yes a real reset not some dodgy disconnect battery thing). Also got other little things that was picked up by the data stream fixed.

I am not sure if the ECU reset has cause any changes, but car seemed to be more responsive now..

Oh this is for an R34 GTT. Would say the data streamin well worth the 100bucks to find out what faults there are with the car and also the ECU reset.

My hicas light tends to come on sometimes after high speed or going over bumps. I have an aftermarket steering wheel fitted. Once i turn the car on and off it dissapears though. Apparently aftermarket wheels can do something to the hicas sensor or you might have a faulty hicas sensor. My car seems to drive fine even after the light has came on so i dont worry about it; however i've read in a past post about someone nailing it on the freeway and the hicas light came on and the car started changing lanes by itself at 160+kph.....I guess you could always get a hicas lock.....**** hicas.
