Diy: Stop Hicas Warning Light (Without Bulb Removal)

[Dose Pipe Sutututu]

I reckon the easiest way is to pop the pin from the relevant wire out of the plug and elec tape it to the loom . It doesn't take much longer and is reversible , not that you'd want to but why butcher something if doing it this way is so easy ?

A .

It's actually a little harder

I started with a small screw driver than just gave up so side cutters and headshrinks came out

[Chris32]

Did mine yesterday, with minimal time before kids soccer out with the snips and some electrical tape. No more light

[discopotato03]

A mate of mine who knows wiring , and has a good collection of pin prods did mine . A sparky I once knew used to grind mig wire which is good because it's fine and stiff .

Same result , cheers A .

you sure you cut the right pin? please use the schematic I posted on the first page

[Chris32]

It's green with a white line along it (mine was anyway)

All good,, I took the ecu out too but once I plugged it back in all was ok. Cheers!

Took the HICAS computer out AND cut the wire.

Will you be upset if we lol?

[Fantm 34]

Well I just thought y would u need a computer for something u just pulled out...

Sorry for the bump

Ive just removed the entire hicas system in my track car.

I didn't realize that power steering could be an issue.

Ive removef the entire hicas system including ecu and all the wiring back up the car.

Am I going to have issues???

[GTSBoy]

You may just have to work out a way to power the rack valve so you get assistance. The HICAS CU definitely is involved in the decisions about how much assistance you get.

God damn it

The power steer resivour dipstick has a magnetic reed switch in it,

the float on dipstick has the magnet, and reed switch is inside the dipstick.

Reed switch inside the dipstick can fail, I repaired mine a few yrs back.

If your switch has failed. the switch has a inline plug, unplug it, if light goes out then you have found the problem,

the switch is faulty

Jaycar had a new reed switch for $2 I pulled the wires with gromet intact out of dipstick paying close attention to correct height. took a solder iron to it and replaced reed.

easy and cheap fix.

solution = light went out.

cheers

Guys, just a little addition for those wanting to remove the pin from the loom plug rather than cutting the wire.

After about 15 mins trying to push the pin out, noticed there was this grey cover on the plug. If you lift that up you can get to the latch which holds the pin in. I just used a tiny flat head screwdriver to lift up the latch thingy while pulling on the wire. This was on a Series 1 R33 Gtst, but hopefully is much the same for others.

Thanks Johnny for this wiring tip. Got it sorted today after lock bar install, and no more HICAS warning

I just got all the hicas pulled out of my car,R32 gtr 1990 model and the mechanic said pull the globe out.Was checking out this post thats says pin 15 but my workshop manual says pin20 feeds the warning light,so maybe R32s are different???Anyone else here done it to this model?

Where in the boot is the hicas Ecu on an r34?

Where in the boot is the hicas Ecu on an r34?

I believe if you open the boot, squat down, and look directly in.. You should see it.

It may be covered by a panel of felt/boot material, but yeah.

On R32 it is near driver's side speaker. Shouldn't be too far away from there in a 34.
