Well when you have a switch like that it ussually is two driving modes, didnt know the 34 came with it but basically tunes the drive down in snow, or off in off, or launch mode if you have that option too.

Nothing fancy, most cars ive driven have that feature.

nope na doesnt have traction control. the snow button changes the gear ratios and said above, prevents wheelspin.

yup i drive with tc off everyday....don really like traction control much

from what i know non turbo came out with snow mode and turbo has TCS. dont think auto or manual made a difference. snow mode turned on only works on take off, in 2nd or 3rd (not sure which one) like said above to prevent wheel spin. U shud have a 'snow' light on the dash panel. TCS monitors a bunch of inputs and works continuously. shud have 'TCS' light when turned on and 'slip' light when slip is detected and starts working.

i dont think snow mode wud actually change gear ratios cauz thats like a teeth on gears. but it does sumhow manage to bog the engine down so power is cut a great deal.

correct me if im wrong, im a new onwer of a r34 so im also finding out alot of new things on the car.

thanx

Hi guys

Ive some questions pertaining to the AT snow switch. I have discovered theres no light on the dash to show if AT Snow when i flick the switch. Anyone knows what is the problem? How can i fix it?

Can I check what is the position of the swith when AT snow is switched off?

Secondly, i think the previous owner drove the car with the AT snow turned on as it was pretty sluggish till i toggled the switch. Will prolonged driving in AT snow mode damage the vehicle?

Thank you

thats one of the things i'd like to find out about also, prolonged driving with switch on, also is there any sort of speed limit u have to follow with it on.

turn ur ignition to reds and u shud see 'snow' light up in the right hand side cluster of warning lights (above engine temp gauge), regardless of the actual switch position. maybe ur globe is buggered behind there.

I think the globe has fused in my car...but do u know what is switch position when the AT snow feature is turned off? Thanks

    • Thanks heaps Duncan and GTSBoy. I'll get my old man to sit in the driver's seat and turn it on and off while I test with the meter. Or maybe other way round, depending on whether he remembers where his glasses got to
    • This is the GTR fuel pump. Yellow shows 12V, orange shows earth. The ECU provides the earth to activate the fuel pump relay. The ECU side of teh relay will pull low when the ECU activates. This is the RB20 fuel pump. Almost the same, but a little simpler. You can see I indicated (above) where the 12V line goes down to the RB20 diagram on the overall diagram, whch shows both RB26 and RB20. This is where I show it coming in on the RB20 diagram below. You can see that the dropping resistor is handled differently. When the fuel pump control is not providing earth to the pump, the pump earths through the dropping resistor and thus runs at lower voltage (some is wasted over the resistor) and runs slower. I showed that "not 12V and not quite earth" portion of the wiring in a paler orange. The rest of the wiring that I did not colour on that little section below the pump would be orange when the fuel pump coontroller is providing earth. This drop is handled inside the fuel pump controller in the GTR. Regardless, you can see where 12V is supposed to be, where earth is supposed to be. The key on prime is via the ECU providing the pump for only a few seconds the switching off. You should be able to see that happen.
    • Yeah so when you turn key to IGN the fuel pump should run for a few seconds. If you find the fuel pump relay (and have a multimeter, and a second person) to can check the relay inputs.  One trigger pin should be either fully earthed  The other trigger pin should get 12v from the ECU for say 3 seconds when you turn key to IGN, and at all times that key is at START (note, I said this from memory, it may be the other way around, ie one pin always has IGN 12v and the earth has continuity to earth when you turn the key) One Pin should have a good battery voltage The last pin goes to the fuel pump + Also note that if the power to the relay is good, and the relay is working, it is worth checking the pump has a good earth too. There is a computer in the standard system that increases the earth resistance to slow down the pump when not required, pretty old school and it may have failed
    • All this talk about fuel and fancy ECUs, meanwhile my poor old R32 has neither.... When the ignition is turned on, should there be power running o the fuel pump constantly or just for the few seconds it usually takes to prime the pump? About to go have another look at it, have watched some YouTube vids on how to use a  multimeter and looked at some wiring diagrams but really have NFI what I'm looking for because electricity is invisible  
    • Yuh....but weren't all the supertourers, except maybe the Audis, FWD? I don't recall any of the others being AWD.
