R33 Abs Problem Fixed! For $4

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.

The problem with mine was that my abs stopped working.. No idea how coz it was working few hours b4 hand..

Anyways i found the problem to be a dead solenoid. If you receive same error you will have to replace the whole abs unit. Only cost me 80 bucks i think 2nd hand.. Fixed my problem..

but im glad you got your fixed for 4 bucks.. good work on hunting down the problem

Hi guys, does anyone know the part number / code for the substitute Panasonic Relay? I've checked the wires, fuses and wheel sensors appear in good condition so I think its the relay.

Nissan quoted me over $100 for a genuine one when I enquired. This was after they told me they couldn't help me diagnose the issue because they couldn't get their consult unit to interface with my factory nissan ecu, there is possibly something wrong with your ecu.... Absolutely Hopeless bunch they are, I had it interfacing with Nissan Datascan yesterday except that software doesn't read the ABS fault codes....

Does anyone know a decent performance workshop in the Illawarra / Sydney region that is familiar with Skylines?
