Well guys as some of you may have read from another post I created I have been having issued with my cars ABS SLIP VDC lights coming on the dash

The problem is intermittent in that sometimes "rarely" I could do a whole drive to Brisbane from the Gold Coast without the lights coming on. Where as other times when the ABS dose its self check usually once the car has been turned on and gotten up to 10kph it will then start pumping the pedal and make lots of noises from the front drivers side whilst at the same time the speedo wont be moving or is not displaying the proper speed.

The problem has become progressively worse over time

I was told by the local brake shop who hooked up a scan tool to the car that the front drivers side ABS speed sensor was throwing a fault code.

So I got a 2nd hand one off a 350Z from a wrecking yard posted up to me, I switched the sensor over last night and took the car for a 400M drive around the block and everything seemed to be going perfect, ABS was working and no funny noises

Anyhow in the morning when I went to work I got no further than the end of the street "100m" before the lights came back on as the pedal started making its funny noises

I noticed when I changed the sensor last night that it might read the speed of the wheel by magnetic fields or something as there was no COG/gear just a flat bit of metal that sits close to the inside of the wheel hub/baring

I also noticed it looked rather rusty/dirty where the wheel hub/thing was spinning near the sensor so I am going to pull it off again in the next day or to and try and scrape/clean some of the crap off and see if that fixes the problem

I was so pissed off after having switched the parts and thinking that everything was going to be FINALLY sorted particularly after the drive around the block. If I didint install the sensor properly one would think that the warning lights would come on straight away when the car was turned on/driven around the block

Hey

Sorry to hear about your woes mate. Ifeel ya

I had a similar problem with my car when i first got it. When i scanned it, it reports that the wheel speed sensors are faulty.

Had a mechanic look at them and turned out it was just loose and dirty. So give it a clean when you can then see how you go.

Maybe the replacement sensors themselves are no good? Get the part number and post it here so i can help you look up prices.

Also, if it still happens afterwards, try to swap the sensors around from left to right to troubleshoot it.

i am having similar issues i have resently fitted extractors, high flow cats, and disconnected the battery so as to do a system reset and as i took off after the front wheels started to lock up but only when i had turned my steering the slip flashed than i breaked and it stoped flashing drove forward again and it happened again than the vdc was illuminated and slip also. pissing me off so much, so now i have to disengage vdc before i go any where once engine has been switched off.

but if i start up and drive in a straight line the slip and vdc become illuminated, there fore no traction control on. any ideas and these sensors where are they? thanks

Well I not sure why your having that problem, Im thinking that I might pay a visit to Gavin wood in the not too distant future as he has all the fancy scan tools to work out what exactly is going on Im thinking that you might have to do the same or go to a willing Nissan dealer and have them plug in whatever their tool is "consolt" I think is what its called

      Possible swap on R34 RB20DE NEO?

      By GTSBoy · Posted

      If the RB29 box in the car is a push clutch, then yes, you will need to deal with the pull clutch on the turbo box. You either buy a pull clutch and don't use the old one, or you do the things needed to convert the turbo box's clutch arrangement over to push. Which is a bit of a f**karound. "Making" a custom tailshaft is the easy part. But you will need to source the front clip yoke - the bit that goes into the output of the gearbox. These are not as easy to find. They are out there, but they don't grow on trees the way that they used to.

      Turn signal wiring question

      By GTSBoy · Posted

      Indicator bulbs are way too bright to use as a "corner marker" (we call them parking lights too). Sure. Go ahead and do it. But realise that you wil need to come up with all your own wiring to do it, as no-one will have a standard howto worked out for Skylines. It's just a matter of abandoning everything that Nissan have done and starting from scratch. You'd probably be better off retrofitting tailght/brakelight globe bases into the front indicator housings and using the taillight circuit for your corner marker and the brake light as the indicator. You'd need to work out how to kill the marker circuit while the indicator is flashing, otherwise it won't flash on-off, just bright-less bright.

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
