Firstly use the search function. There is heaps of info on here and you will get more help from others if you üse search first.

It could be many things from the fluid level, blown fuses, loose screw in the Attessa ECU even, dirty sensors in the wheel hubs, G sensor.

Is the ABS light on as well ?

Check the 4wd fuses in the fuse panel in the cabin and the fuse in the engine bay.

Check the fluid in the reservoir in the boot on the drivers side behind the trim panel (with ignition on)

- then get back

No abs light on, checked the attesa box in the boot had 9 flashes, abs actuator relay or circuit. But the ABS has been removed :s

The unit is reporting correctly (9. abs actuator relay or circuit) Yours has been removed so that s norm

Call the owner or visit him and ask what he has done. Doesn't sound like it has been bypassed in any way as its working as it should (Error Msg)

Maybe it is possible to bypass so the error is not reported.

Your solution may be to remove the globe from the cluster if it annoys you.

Got in the car this morning to take it for a drive and the light wasn't on I think I'll see how it goes next few days. I don't think it's anything to worry about. Thanks for your help.

Nizmoman asked the obvious question, "Does it have an aftermarket steering wheel?"

Now you must do some test driving NOT on the freeway, just normal suburban stuff that involves corners.

If your light stays off after the 20 or 30 minutes, the steering wheel boss is your problem.

A lot of aftermarket wheel kits don't locate the sensor correctly in the boss.

So the car thinks it's turning a huge circle when it's actually going straight ahead.

If you do suburban driving with corners etc, the HICAS ecu won't care but on a freeway with lots of straight ahead driving, eventually the HICAS ecu will throw a fault. (I found it to be around 20 minutes of straight steering)

Key on/off and you're usually you're good for another 20 or so minutes before the light comes on again.

However if your light returned even in suburban driving, you'll have to keep digging.

Hicas would put Hicas light on (if globe in cluster) and would be associated to 4WS and steering wheel as above, lock bar?.

but suppose could be an issue too...I'm not sure how 4ws and 4wd are connected.

First post mentioned 4WD light is on.

This definitely involves ABS, Brake system, Attessa ECU, Resevoir, Speed sensors, Pump, Solenoids and the G sensor. (and Attessas electrics)

So the guy I brought it off got back to me, says he never realised it :s but what ever!

He also informed me that it has a tomei hicas lock kit on it so maybe that has something to do with it, I don't even know what that is so will research it and see of it could be the problem.

Maybe I'll also get a new boss kit just to reduce the source of problems to choose from.

      Duncan's V37.......race car?

      By Duncan · Posted

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.

      Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.

      The BES920 is like the Toyota Camrys of coffee machines. E61 group head is cool, however the time requirements for home use makes it less desirable. The Toyota Camry coffee machine runs twin boilers and also PID temp control, some say it produces coffees as good as an E61 group head machine.
