It means intermittently there's a problem with the 4WD system.

In the boot, in the RH corner, behind the lining, there's a fluid reservoir. Check the fluid level is between the marks (check with engine running). Takes auto-trans fluid.

Otherwise, there's a faulty earth contact (maybe, have fun finding that one!). But I would lay money on the fluid reservoir.

I think its somewhere different on R33. Can someone confirm this.

My car also does the same but it happens if the car is idling for more than 2 mins.. You can actually hear the 4WD drive pumps running and as the light turns on the pump turns of at the same time... while in traffic i turn the car off and then back on and it back in 4WD drive mode...If i take of while the light is on then its in RWD....

This is quite annoying especially as i drive it everyday in Sydney peak hour...So if there is a fix it would be great...And yes i have check the fluid already..

I dont think the reservoir being full or near empty is that important...if its bone dry maybe but as long as there is oil in there.....and someone correct me if i am wrong but i think it doesnt have anything to do with the split drive system...I had an R33 GTR before and have replaced the clutch in it myself and it looks as tho that oil is the feeder for the gearbox oil...i was under the assumption that the gear box works on the Drysump principal....i may be wrong but thats what i can gather and it looks like the split is further towards the front of the gearbox on via a clutch pack in the transfer case ....i would be checking for computer related problems ...run an on board self diagnosis test and see if you can extract and codes from the ecu.

O k I just went to check it out. The the empty max mark is halfway on the bottle which the fluid should be in between right?

The bottle on my car is "totally" full!

Can this make the light come on?

Does your abs light flicker before the 4WD light comes on?

The bottom part of the reservoir is the return. If the air gap between the fluid in the bottom and the top part is the big you may need to bleed the 4WD system. There is a max gap something like 5 or 10 mm.

Another common problem is earthing.

You can get an error code out of the 4WD computer. I forget how to do that, I can look it up in the manual on the weekend.

Thanks much appreciated. I will will drain my fluid to the correct level first and then bleed if I have too. I will wait for the error code posting

Thankyou once again.

Hey RH9GTR I know how you feel LOL

Its annoying!

There is a procedure to bleed the 4wd system. From memory on a 32gtr it goes something like,

1. fill the reservoir to about 3 cm over the max.

2. remove the air from the bleed valve on the unit above the rear diff.

3. turn the ignition on

4. disconnect the bleed connector which is behind the kick panel near the accellerator pedal. It should be a white or yellow wire with an inline connector that you need to disconnect. You should hear the pump start for a couple of seconds.

5. there is a bleed valve on the back of the gearbox/transfer case, you need to unscrew it nearly all the way, then open and close it quickly for 1 sec at a time. You should hear the pump pulse then close then value. Do this until all the air has gone.

6. there is pipe (the return) on the side of the reservoir on the tail light side (the reservoir is on the right hand side in a r32). Open this to drain the excess fluid by connecting and disconnecting the bleed connector near the accellerator pedal. The pump should turn on when you connect the bleed connector if not turn the ignition off and off then try again.

7. connect the bleed connecter and turn off the ignition.

Sorry for the confusing explaination, it is easier with pictures although the engrish in the manuals is probably worse.

Unfortunately this didn't help my friend, his problem is abs or electrical related.

DR,

I have the same problem, except my ALSD light comes on as well. If the fluid is over 12 months old replace it. Mine is just getting to 12 months now and I have noticed that the lights are starting to come on more frequent. Bleed the system almost completely making sure you keep re-filling the 4WD Bottle.

I have also noticed that removing the connection from the computer under the back shelf and using some connector cleaner on the plugs also stops bad joints which also can bring the light on. If this does not fix it, then sell it and buy another one. I have a friend who spent $20k and 10 months and he could not find anyone in Sydney who could fix it. His come on continuously so it was a slightly different story.

      Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed

      hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me

      Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
