What Would Make The Hicas Light Come On?

Just wondering what would cause the Hicas light to come on while driving.

The other day I was driving (in the rain), when the orange Hicas light on the dash came on. The steering went really wierd, varying between too heavy and too light. After about 1 minute or so, I pulled over, turned the car off, turned it back on and the Hicas light stayed off, haven't seen it since....

Any idea what might have happened there?

check your power steering fluid in the engine bay and also the hicas 'bottle' in the boot (?)

maybe they are just below the 'line'

also check the connections to the battery for corrosion - I had an issue like that where one of the wires on the positive terminals was corroded and made an intermediate connection causing the hicas light to go on and off while driving.

Thanks guys, Merlin I must have missed your thread on my first search, but I saw it afterwards and answered some of my questions.

Seems a bit wierd that it came on once, then when I turned the car off, and back on again it never came back.

I think i will probably end up getting a lock-bar anyway, but I was curious to know why it may occur. I will check the fluid levels to start with.

my hicas light comes on afta awhile of being on a freeway, ive never worried 2much about it, my car has a momo wheel fitted, any ideas bout these tomai hicas kits?
Is the BOSS kit designed for HICAS?

I have used a Tomei Lock kit for the last 2.5yrs, works well and have had no problem. But if your Boss kit is NOT HICAS compatible, the HICAS light may still come on, so you may be required to remove the globe.

HICAS is the 4WS system.

Quinny: do you have an aftermarket steering wheel?

No, it is stock. The fact that I have not seen the light again could just be a glitch or something, but it is rather strange. I think I will probably get rid of it anyway, I have never been a big fan of 4WS.

yeah there is a bottle on the drivers side of the boot, behind the boot lining.

i know my car is supposed to be 4WS but how much does the rear wheels move?

i have sat in my car with the door open watching the rear wheels as i turn the wheel completely and they never moved.... how would you find out if something like a "lock kit" is installed?

Best notify everyone that you have a 32 :). R33s do not have a resivour in the boot.

I believe the 4ws only operates when car is in motion

Isn't the remote resovoir the attesa resovior? Which feeds into a pump under the boot?

Whereas R32 hicas is taken from the power steering pump...

I dunno why it goes on. I fixed it by removing the warning light from behind the dash. No warning light, No problem...

And I doubt your car would have a lock bar.

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
