Today I started my car and both my ABS and 4WD light stayed on while driving. I got fuel, restarted the car and they were both still on. I can only assume something has happened in the past few days for this to happen... what are the normal symptoms of this?

Also, I can hear an intermittent friction sound coming from the front left of the car, as I speed up it gets faster. Its nothing to do with the pads being to close to the discs I don't think... could this be an ABS problem noise?

Recent work done to the car included a HICAS lock bar and new clutch.

any help appreciated

Try checking over all your fluid levels. The warning light can come up if your brake fluid is low. Don't forget to check the fluid in the boot aswell.

Bit obvious stuff to check, but you never know. Goodluck

when the 4wd light is on the attessa computer in the boot will be flashing an error code - go and check how many times it is flashing against the list in the 32 gtr workshop manual. If it is related to the abs sensor it will show that error #

I found a thread on here about the same type of issues...

forgot to mention I have 1994 R33 GTS4,

One thing I noticed is once the 4WD and ABS led flashes the SLIP led doesnt work anymore, normally it flashes when the rear wheels loos control or slips. which means it has switched back to RWD from 4WD.mmmmmmm, No I dont know why ABS led allways cometogether with 4WD??????

Maybe a electrical problem..................

Sounds like you rear ABS sensor/s are faulty or damaged.

Both ABS and ATTESSA systems use the ABS sensors to determine slip/skiding/etc.

I think it might be the G sensor or ABS sensor for me.... How much is a new G-sensor?

you don't want to know lol

error 16 is lateral g sensor so at least it is nice and specific.

Start with the g sensor unit itself, it has a small window on the front that goes red if the sensor is screwed.

much more likely it is just a wiring issue though.

there are 2 plugs on the g sensor, one 4 pin, one 6 pin, you need the 6 pin. I don't have the colours in front of me but in at the bottom of that plug (the 3 wires), centre is earth, one is 8v in and the other is signal out. Make sure you have power at one of the outside wires. More details on CH66 onwards in the gtr service manual its worthi finding a copy

I removed both of the plugs connected to the Gravity sensor and plugged them back in, no wires are broken or disconnected or loose and the 4WD and ABS lights are still on. I am stumped with this one :)

Where are the speed sensors ali? How many are there? I am assuming this is different to the G sensors?!

there are 4 of them one for each wheel, im not sure where they all are, but i no there one close to the alernator, thats the one that wasnt plugedd in my car,

i am 100% certain that one speed sensors are f*ked or not pluged in i had the same problem

    • Hi soviet_merlin, We appreciate your concern regarding this possibly being some sort of PR/Political hype, I assure you that is not the case, I wish we could claim something like that, but in this case, we merely reached out for comment on the basis of the outrage we too felt, as those heavily in the automotive industry. Ps. the original source in the social media post is CarExpert not CarExplore.    Best, CE.
    • Made a bit of a discovery, but while I was cruising, I randomly decided to test to see if it worked and it showed up on my IC7. The entire time I tested it before, I never thought to turn the ignition on. I only tested it with head lights turned on but with the ignition off. Huge oversight on my end. I’m a dummy. I know. 
    • G'day all, I have drilled and tapped the hole for the relocation of the timing belt tensioner. That was straight forward. I'm unsure if I need to also put another hole for the smaller stud that the spring behind the tensioner catches on (this is how it seems to work in its original spot). Or do you not use the spring behind it and just torque it down? Thanks in advance, I did a search but couldn't find anything related and it doesn't mention it in the rb30det sau guide.
    • Hi All,  just thought I would provide an update as I know smooth (Matt) was on this forum from 2003.    my brother Matthew passed away end of may 2024 at the age of 41 from liver failure. I am not sure how many of his original team krazy friends are still on here or active but thought it reasonable to let the forum know.    if you have any photos or pictures it would be great if you could share them.    it took me a while to work out he was active on here.    thanks so much
