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,

its like iv got no power steering anymore and yes iv checked my fluids,

i got so pissed off i took to a workshop and got them to fit a hicas look bar with all lines removed.

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

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.

    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
