my 4WD light comes on every now and then when i start the car, although all i have to do is turn it off then on again and it goes away. By the way, the car loves to get sideways when the light is on... good old RWD :whistling::):P

Doesnt say what the abnormality is - it's just a warning. As per Andy's post it obviously stops working otherwise he wouldnt get it so easily sideways in the dirt.

As the car is constant AWD there is no switch to turn it off or on. except for the synxchro (S) button which I believe acts more like a central diff lock. Which is why the steering gets heavy on full lock when synchro is activated.

Not that I know any of this by expereienxce as mine is 2WD only.

abnormality? like...?

not operating correctly, low attessa fluid maybe (in the boot) ??? dodgy wiring, stuffed attessa pump, or anything related with the attessa stuff, try accessing the attessa ecu in the boot as per another post i showed pics of where its located and read the diagnostic light sequence and check it up on the workshop manual for what is the problem.

i have mine come on every now and then, when it does, i just turn the car off and on.

I also had it come on once because i didnt put the plug back right into the ecu and one end was being held up.

also, i got it when i disconnected the vac line on the bov for some flutter, car stalled and then the 4wd light would come on every now and then along with the car driving like poo. It went away after a while, guess the ECU taught itself.

Please dont ask for manuals.

Other than that, I dont have a 4WD light, mines a HICAS light, same thing as I have a 260RS dash, and mine never comes on, only when the key is in the ON position but not actually started the car....?

But all that said, Brad is spot on, check fluid levels and/or attessa system!

4wd light on all the time = not bled or no fluid...if it goes sideways, its prolly not working, check the resovoiur in the boot and see if both the top and bottom tank is full? and maybe bleed the system too...might fix ur problem...but my light stayed on when i put my engine back in last week until i bled the system out :D

There is a $189 / 491 page R33 Service Manual, I think thats the one they mean. There 'was' once a link to it for a downloadable PDF file of it, but thats been shutdown. Im pretty sure JPNZ own the rights to this translated manual, and therefore it breaches copyright if it is 'exchanged' between ppl wiothout $$ rights going to JPNZ.

I dont know how Funky has gotten around all that, maybe becasue his manuals are in Japanese writting and the local Japanese copyright may not be applicable in Australia, whereas JPNZ is a New Zealand company who translated this Japanese manual, and being based in NZ therefore AUS laws apply.

Hope that helps! I was lucky enough to come across the service manual in pdf format (via GOOGLE, hahahaha) just before the webpage was shutdown. I saved it to disk and have not reproduced it in any way shape or form. Lately I have been asked a lot if I can forward this pdf.file onto ppl.........

My manual came with the car - its a JPNZ one, but only 258 pages. An abbreviated version like the type you normally would get in any jap car that tells you every useless bit of info about how to turn lights on and off and how to drive the car up and down hills. But never contains anything mildly important if you want to fix something - standard reply is, "if in need of servicing please refer to your nearest Nissan dealer."

All that aside, it did have extra info on the 4WD light dilema. And I qoute:

The 4WD light will illuminate when the ignition is turned ON and it will turn off when the engine is running.

When the 4WD warning lights shows or will not illuminate when the ignition is ON, have your vehicle checked by your Nissan dealer as soon as possible (told you it was helpful)

If the warning light flashes check that all tyres are the same size and brand (This includes air pressure) If the light continues to flash, then (you guessed it) have it checked by your Nissan....

If the light turns on when driving, the ATTESA system will cease functioning but normal driving will be possible.

The 2nd last point makes sense - if the tyres are rotating at different speeds then the ATTESA isnt going to engage because it will be fighting against itself like trying to engage two gears at once, so it will opt out and not engage at all, hence the warning light.

So light could be on because of uneven tyre pressure? Would that apply to just the rear tyres though.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      After market rear camber arm adjustment

      By V35Newbie · Posted

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
