I have a problem with my HICAS but never get the light on the dash whilst driving.

I've put the hicas in adavanced diagnoistics mode,

I get error codes 22 and 32 which both have something do do with the neutral switch,

anybody had this problem before or can point me in the right direction as to go about fixing it all the plugs into the gearbox look ok!

BTW its a 1994 R33 All Electric type HiCAS (No Hydraulics)

Thanks

22 is the steering angle sensor - have you replaced your steering wheel with an aftermarket one? If so you will need a HICAS boss kit. It's also not unheard of for the steering angle sensor to crap out either. The sensor is in your steering column.

32 is the engine speed signal not present - I don't know where the signal comes from in the R33

Dude you should of bought a silver one, that's the problem.

Also you need to put a stock exhaust and 14inch rims on it, plus 80 series profile tyres. Bumpin'

:(

Dont call me DUDE :)

Mate it sounds like you only have a stocker when you get a HKS super Drager zorst and some 18 X 9" wheels (and a clutch) we will take heed of your comments :shake:

My car still has the stock steer wheel

How do I test it?

when in advanced diags I turn the steerwheel and the rear wheels move about an inch or so left and right.

I have a switch that connects the speed sensor (This disables the speed limiter) but I rearly use it, could this be the cause of this code? although I did reset the ecu before running the diags! which would clear this error.

The engine speed sensor couldnt be a problem as the rpm cut still works and that would be a part of the crank angle sensor circuit.

The 32 code error could be many things (I still think its the Neutral switch) as below

HICAS 1994-1999

22 Steering angle sensor not present

23 Steering angle sensor neutral or not present

32 (Auto) Inhibititor switch input not present,

(Manual) Neutral switch input not present

32 Engine speed signal not present

Can anybody correct me if Im wrong please!

    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
    • When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
