MY ABS Story, 1997 R33 Gts-T: (skip to see resolution)

Over the past few months my ABS warning light has been on, no big deal, breaks still worked fine and it somehow it passed NSW roadworthy. But I wanted to know what the problem was and I didn't want to spend $250 on a replacement ABS unit.

I had the car data streamed and It responded with "ABS motor [off] or fail" no real help.

My Issues started about 6 months ago where the ABS motor would not switch off, it continued running even when the car was completely off. I figured faulty wiring or faulty abs module, and just unplugged it.

I downloaded the R33 workshop manual and traced through all the wiring, fuses and relays*

I found two 30amp SPDT (single poll double throw) Relays in a module attached to the abs pump

Part Number:47605

Long Story Short, I tested the Relays one would Close Circuit when powered, the other one would not.

I cut the faulty Relay apart and found the small connection point broken off, I re-applied the contact and put everything back together, All worked 100%. I will buy a new relay and replace the old one. The original Relay was matshita, but it can be replaced with a Panasonic.

For a $4 part the problem is solved. This is definitely worth checking.

hey guys,

this problem just happened to me a couple of days back. after a good thorough wash, this stupid ABS light comes up whenever i start moving my car. at first it was intermittent but now, it became permanent.

i have decided to do the following checks before bringing down to a mechanic.

1. check, clean sensors

2. pull out the relay

however, i am not really sure which the sensors and the relay are. it will be great if someone can help me out with this.. pics do a thousand words =)

Hey has anyone got any pics of this relay? as I have an 96 GTST with the ABS light on and its realy starting to piss me off?

I know its an old thread but surely someone out there would of done this check surely??

Regards,

Draren

Sorry for digging this thread out of the grave, but my car has just failed the e-Safety check due to the ABS light showing!

I'm about to ring an auto-electrician to see what he can do. I would have had a crack at it myself but am at work and need to leave for Melbourne on Thurs (it's Monday today), so don't have time.

Will let you guys know if it works!

Sorry, forgot to follow up on this... yep, basically I just replaced the whole box that contains the 2 relays. Took me 5 mins to replace and worked like a charm straight away! Only downside: cost me $75 and the guy tried to charge me $100. I think I got ripped off? Nevertheless, I had to buy it on the spot as I really needed the car registered quickly and didn't have time to play around taking the relay box apart and waiting for relays to arrive from overseas :)

Was also thankful that it wasn't the ABS pump - the parts guy said it would have been about $250-300. Also think that's a bit steep?

I ended up just buying another block relay, was impossible for me to desolder the pins off the relay as I don't have a proper desoldering tool (with built in vacuum) using a hand vacuum pump and a decent side soldering iron, I still couldn't remove all the pins.

Probably easier if you brought the relay to an electronics guy and ask him to desolder & resolder the relays on. Relays can be bought from Jaycar.

I'll take photos of the horrid mess I made tonight LOL

remove the relay block (1x 8mm bolt) and unplug all the connectors... give it a hard shake, it is sounds loose I'm sure it is dead.

I actually threw mine in the bin so I can't take photos of it.. but if you crack open the housing there are 2x pcb flush mounted relays.. I tried to desolder them but don't have a proper vacuum desoldering iron. Ended up melting half the PCB so I gave up. A hand desoldering pump won't do it, as the relays are flush mounted.

Went to a wrecking yard and paid $50 for an entire ABS unit and block relay. Tested on the spot, worked done :)

    • Welcome buddy! Plenty on here and YouTube. What are your plans for it? Good luck with the Rwc and Rego bud!
    • Love this so much! Please post a photo when you have a bike on the trailer.  I was a little bit worried about having a tow bar on the Skyline, but having it hidden behind the number plate is genius
    • Came here to say, put all the wiring from the new motor and gearbox in that you can, then throw the stock ECUs in the bin, and get an aftermarket ECU. Should be pretty easy if you can use a multimeter and read a wiring diagram to then use a PNP aftermarket ECU to suit the motors wiring loom, and make the minimal changes you will to get it to work in with the body loom (If any). This will mean you can very easily circumvent/bypass the Park/Neutral start disable switch, and get everything running really easy!
    • If the roof is dual skinned the whole way, IE, there's a "top" metal piece, and a "bottom" metal piece, to slow it down as much as you practically can, you should be able to get an attachment for a spray can/your spray gun, where it is a long, thin flexible hose, and when you're "spraying" it is spraying it in every direction possible. The I'd get that, and feed it through the roof as much and as far as you can. It's basically like fish oiling the car, but you're soaking it in rust converter. Then do the fix like Murray has described having cleaned up the existing metal as much as you humanly can. I'd also throw as much rust converter on that exposed metal before putting the fibreglass/metal filler over everything.   As for welding a replacement in. I've owned my own MIG welder for about 10 years. I've also worked in an industry doing MIG welding for a job for about 3 months dead straight, and we were doing 11.5 hour work days 5 days a week, plus a Saturday 6 hour day. (I then moved over to running the massive CNC plasma as I could understand the technology, and work with the main guy out there). I also f**k around with my welders a bit at home. So what I'm saying here is, I've probably got more hours on a MIG gun than you'll manage to get under your sleeve doing home sorts of jobs over the next 5 years. I also have an ACDC TIG that I got myself a year or two back. I've got a short amount of experience on the TIG only. My home MIG is also presently setup for doing thin sheet metal. Unless I didn't care about how that roof looked, and I just wanted a functional metal roof, and it being out of alignment, warped, and bowed, I would NOT attempt a roof replacement UNLESS I could do it as a whole panel like Murray described where the spot welds were.  Welding has this REALLY annoying thing, where if you want something to be perfectly square, unless you can clamp that thing to damn perfection (Welding fixture table), it is NOT going to be square, so you start to learn, the type of metal you're working with, how thick it is etc, and weld in VERY specific ways, and by knowing how YOU are as a welder, so that as the welds cool, the metal work pulls itself into place. If you want to see some cool tricky shit done, Bennets Customs is an Aussie guy, and he mentions a guy a lot call "Kyle", who is from "Make It Kustom". Watch some of their welding videos, especially on sheet metal. You can use the welder to shrink the steel in, and you can also use the welder to stretch the panel out. When you have the skill level that I have, you can shrink the metal in and out... But never on purpose like those two guys do. You just manage to f**k it all up. Then I smack it around with a hammer till it sits lower than I will want it too, then I shove filler on top and then pray to deitys that I can sand it into some form of sane shape that doesn't look like a dog has taken a shit, after eating a tonne of pumice stone... I'm all for DIY, and for learning, and please, feel free to give it a go, but be aware, you need to live with the consequences of how time consuming it is to do, AND that it's going to look no where near as good as what you can make it look with just some filler now. Oh AND, even once you replace it, it's like to still rust away again eventually, because you'll have missed putting primer and paint on some part of the newly welded in sheet metal, or against part of the existing metal you couldn't get to...   Oh, and to weld all that in, you will need to pull the window out, and strip at least the roof and A Pillars of interior trim and wiring. You'll then need things like the big fire proof/weld spatter proof mats to lay down, OR you'll end up needing to strip the ENTIRE interior to avoid sending it all up in a ball of flames. If you want to see how annoying sheet metal is to weld, head to bunnings, buy there 600x600 1.6mm mild steel (Not GAL!) sheet, and cut a few pieces, and try and weld them together. Then understand, 1.6mm sheet is nearly 50 to 100% THICKER than the cars sheet metal.   The photos I posted before, I'm replacing with 1.2mm thick mild sheet, and it's very easy to blow through both the original steel (Especially if I hit an area that should have probably been cut out a bit more) or straight through the new sheet metal. And I'm doing the floor, which can be hidden easily, and doesn't matter how pretty I make it, as long as it's damn strong! I'm also doing it in a 4WD, that has seen many off road trails, and doesn't need to look that pretty ever
    • This sounds like a perfect excuse to install a Haltech R3.
