[ali-turko]

hey guys,

im in desperate need of your help, one day i was on my way to work my steering was fine (no hicas light)

later that day i start my car and immediately my hicas light appears, but i noticed when the light is supposed to turn off there is a very quick flash so the light stays on,

but nothing has changed hicas light is still but i relaise is stay due to the lock bar but is as if i got no power steering.

can someone please help

Have you checked the wiring and plug that goes to the power steering pressure switch and the Power head on the actualy rack??

Also there is a fuse under the dash which might have blown causing the heavy steering.

Check that the solenoid under the plenum is unplugged electrically. I've found this as a cause of a lot of hicas problems involving heavy steering.

which fuse is it?

and i will see if its unpluged from the solinoid

i removed my hicas completely. including the solinoid in the engline bay. the power steering line that went to the solinoid got plumbed directly to the power steering cooler. this made it so i didnt need to replace the power steering pump. i still needed to physically remove the hicas light out of the dash as it stayed constantly on. the light indicates that there is an error with the hicas. there is no hicas anymore! thus no need for the light to tell you theres an error with it.

You can just cut the sender wire on the hicas computer. Bottom right of the smaller plug. Green with white trace line.

And that is the best way to loop the hicas lines. There are a couple of guides on here of how to do it, and I've done a detailed one on ns.com too.
