So managed to track down a g sensor. And boom all the lights go out. massive thanks for your help on this.???

Sweet mate I'll check that pin in the consolt port and maybe get a couple of them relays and a g sensor from somewhere and report back all wiring cuircuits seems to be good so far. Could do with getting this thing off me drive it's like have a bus parked outside.

Update battery been disconnected since last Friday put back on checked the fault codes still showing 61 63. do I need to clear code via the earth pins on the dignostic socket? ok so I've been around the earths at the abs pump. It earths from the pump it's self and it's only a small wire down to the inner wing via a rusty bolt. Getting good continuity to earth. Thought I would take it out and give it a clean checked the resistance that's all good. Still got the lights. Main fat wires are to the relay pack white and white with a red stop So I unplugged the relays from the abs and now I'm only getting code 63. But if I unplug the abs sensors or the g sensors the fault will not change from 63 Im starting to think this is not going to be a wiring problem an all the terminals look mint no sign of corrosion. So it must be a component causing issues What I also noticed today since it's not run since Friday my test light is still in the pump circuit line and the pressure from the attessa pump would have dropped over the last few days. Once you start the car the test light will light up and all the lights go off. 2 seconds later the abs and 4wd light will come back on. The test light and my home made relay stay active for 10-15 seconds once up to pressure the light goes out relay click off. I'm thinking I need a pair of these abs relays or the pump even thou that primes up when you start it, but is that priming for 2 seconds faulting then bringing the lights on and the attesa carrys on with its self checks and all that side checks out, I've opend the box for the valves but I'm sure what I'm looking at in there. Continuity check it and they all beep off every pin to each other like its all fuse together and every pin in the connector is connected to each other. I don't know my head is melted with this thing. time for a large beer.

I thought that would be the case, but I didn't use that one I used the one I found on google to bleed it up by the fuse board up by the pedals. Worked no problem. Thats a good idea I'll try that tomorrow. I did try unplugging a few of the wheel sensors and the g sensor to try and get the Ecu to read different flashes but no joy there still reads the same two. So sort of lead me to believe that it's more the relay circuit than the g sensor. But as can't be 100% sure I'm chasing the correct fault code. Also to find the final relay in the circuit would be a bonus

They all look good but I'm back on it tomorrow got an early finish tomorrow so will double check, There's some proper rotten 10mm bolts behind both the headlights but I've had the meter on them and there earthing. But I would think there earth points for either headlights or engine loom. I've not been near the car since sat night so the battery is disconnected hoping it will clear the codes in the Ecu. I have seen about the grounding of the consult pin but I didn't want to do that in case the info was incorrect for the model and end up smoking something. Is this something else I should be doing rather than a battery disconnecting? What I did find the relay by the strut top the connections were a bit poor. So I tweaked the terminal then I found the relay was a little intermittent. Temporally wired in a standed relay as the Nissan ones are all a stupid shape. But all still the same. That stopped the random clicking. Even after Ecu reset only for 10 mins at a time with the battery disconnect. Also ive put a test light in the main attesa pump wire so I can see when the signal is going to pump. I'm not sure how they came on or when it's a good friend of mines car and I'm a retired mechanic well full time anyway. He's taken it to a few garages and they have no look and cos the abs light is on mot is coming up so I said I would see what I could do. Maybe other thing to mention is the centre diff s button doesn't do anything but the light goes off once you start the car up. The switch is swtiching but I'm thinking that isn't working due to the attesa fault. My friend also said he though it was stuck in rwd but I noticed once I disconnected some loop connection by the reservoir This makes the systems work and then when you drive it it all feels locked up and you get wind up in the diff. So the 4wheel drive mechanical side is working. But once the residual drop from the hydraulics up turn free again. Thanks for your input on this phill ?

Yes g sensor is all connected all ok. All my info has either come from this site or google. I can see that fault codes 61 & 63 are different on the different version of attesa I believe that on the skyline 61 or 63 points to g sensor. this is why I registered on here to make sure I'm looking at the correct info. They don't make this car over here in the uk so no body really know anything about them to help me.

Thanks for getting back to me pal. Im pretty sure that both the relays on the abs pump are clicking. Ive got the whole interior out of the rear and I can't find the relay. i found a basic diagramme that shown the relays in the rear but I think that's for the skylines. all three lights come on with the ignition when you start it they all go off for a second then the 4wd and abs light come back on. Somebody must know where the last relay is.

No the wiring diagram I have is very basic so no plug pinout. The relays on the abs pump are a pair soldered onto a circuit board bolted on to the side. I'm getting 12volts to the relays on the side of the abs pump also pump primes up when you put the ignition on like that circuit is working.

4wd abs light on Hey guys need some help with my stagea rs 4 1996. i have both 4wd and abs lights on the codes im getting from the led off the Ecu is 61 & 63. I have found a basic wiring diagram and in this I can see 5 relays. so I've traced them to 2 on the abs pump it's self one in the main fuse box near the battery and one up by the strut tower. Where are the other 2 located. could anybody shed any light on to this fault as I'm tearing my hair out now. Checked all around the wiring all checks out ok. Just need to find these other relays to see if that where the fault is. any help would be great.

Uk member needs help Just though I would say hello I'm looking for help with my stagea Rs 4 as there is no info here in the uk. Not finding much on the search function on here so I thought I would register. I have abs code 61 and 63 do anybody have any infomation to follow these codes. Everything I have checked has come back good. please help its driving me insane.
