Hey I took my car in to get a problem with ABS diagnosed (Light stays on permanently), this was their response:

"Scan ABS Module for fault codes. Code 21 - ABS Motor.

Checked ABS wheels sensors for operation, all ok on current data.

Suspected faulty ABS motor unit"

I am now in the process of buying a replacement motor. I was wondering if someone could help me identify it. I've attached a pic, is this the 'ABS motor' circled???

Thanks for your help.

ABS is driven by hydraulics. At the bottom of he ABS unit there is an electric (12 volt) motor that drives the hydraulic pump that makes the ABS work. No motor = no pumping = no ABS working.

My experience has been that it is cheaper (when labour is included) to buy a complete ABS unit. Check around the import wreckers for one and compare prices, they vary a lot.

:) cheers :P

Yeah what you have circled is the ABS, what you will find as with most modern systems is that it is the module (like computer) and also the hyraulic motor. Look forward to paying top dollar for one of these... it would be unwise to buy second hand because they are a precise peice of gear and internal clearances are extremely tight, so for peace of mind go new.. bummer.

Jeebuz christ! :geek:

Thats just crazy!

I've bought a second hand unit for $80, which i'll get installed and hopefully solve my problem. Failing that, i'll check out the relay that you're talking about.

Where abouts did you source the relay from?

i got that quote from Nissan in the brisbane area.. Cant remember which one cause i tried a few.

But yeah, the bloke at nissan did tell me to try an import parts place as they will be a lot cheaper... and they were right..

Anyway, i got my relay from rscomponents.com.au. They will have to order it from the UK. I did an exact search (from the info given on the relay) and that's what they provided me with.

hope it helps.

Sorry to bump and old thread..

But does anyone know if a 33 gtr abs unit till work in a gtst series 2?

If worst comes to worst, if nothing else works, then i will have to buy a new abs unit.. Im sure i wont have to.. Probably a dead sensor or relay etc. .

But just curious if a 33 gtr abs unit till work in mine

ta

Best thing to do would be to just purchase a ABS unit looking at the part number. When you mention 'GTR' to a wrecker, they'll just over charge. When I had to replace my unit, I just asked for an ABS unit for an R32 with 'X' part number.

    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
    • You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
    • Funny, but really not funny. Thank god (most) f the world has moved on since then
    • Lots of votes for driving onto a plank first; that is the quickest way I've found, 25mm is enough for my case but that will vary by car It also depends where you are going for. On the 32 I can get to the rear diff with my floor jack if I do that end first, and get it up on stands. Then I lift the front from either front tow hook as high as needed, also onto stands. Sometimes I need a small lift on the other tow hook to get it level enough If I do the front first I can't get to the rear diff because of the angle of the car Other options are getting to the front mount of the rear subframe from in front of the wheel (if only lifting one side, or just do both which is a bit of a pain compared to one lift from the diff), or also the gearbox cross member mount on the driver's side if you are  just trying to lift the driver's side. I This is the jack I use; it says 75mm clearance but of course that is only on the lower section so if you have to reach too far in like the diff you still get stuck. https://www.snapon-bluepoint.com.sg/category/Floor-Jacks/product/Floor-Jack,-2-Ton-Low-Profile
    • On the bright side, the weather will turn much nicer for working outside shortly....sounds like you might need to start on a neighbour's garden next
