R33 Gts/-t Abs Module Wiring Schematic (not Gt-r)

[Dose Pipe Sutututu]

Hey All,

Hope someone has the wiring diagram for the ABS module for a R33 GTS-t... I've looked everywhere and also downloaded a few service manuals which all are focused purely on the engine and not the electricals themselves.

I've found a diagram which shows how the ABS unit is connected theoretically but that's quite useless when determining what wire is what.

Finding ABS schematics for GT-R and it's Attesa systems seems to be easy, but from what I've gathered from my visual comparison is that the wiring between the GTS-t and GT-R ABS / Attesa modules are different.

This is the GT-R one, when I visually compared this diagram to the ABS module bolted under the HICAS ECU it's quite different for my GTS-t boat.

Now you're wondering why the heck do I need this wiring schematic? Well... ever seen a modern car launch with minimum slip and no throttle cut? Yes.. they actually retard timing to reduce torque instead of chopping the throttle which cuts everything.

Now, I am planning to connect my front two wheel sensors to my ECU and will be retarding timing based on x % of wheel slip (front vs. rear).. the higher the delta, the more timing is retarded... however not too much retard, because I'll end up with anti lags and bang bang all day instead lol.

I did plan to run the wires directly from the ABS sensor to my circuit (converts sine to square waves) to the ECU.. but that seems a touch messy going into the engine bay.

So yeah, help me do high 10s down the 1/4 with a stock motor RB25

Manual method. Jack all 4 corners up. Start and run car. Manually spin each wheel and probe the wires at the ABS CU with handheld CRO looking for signals from the code wheels.

man that's way too much effort haha....

I'll just tap the wiring into the ABS sensor at the front... the rear speed sensor (from gearbox) is already fed back into the ECU.. just need F(RHS + LHS)

Just looks fugly if I run even more freaking wires into the engine bay.

Knowing Nissan, the wiring colour would be different from the ABS sensor plug to the rear ABS ECU.

Anyone? hahhaa..

some must have the abs ecu pin out for a GTS-t right?

I have some diagrams pieced together for R33 GTR, GTS4 and C34 ATTESA ECUs, though Im not sure that will help for a 2WD application

Nevermind, I read your title.

Let me know if this looks like it might be helpful and i can send some more screenshots or email it to you when i get home from work in the morning.

EDIT: I haven't exactly included the most helpful part of the diagram here lol but i can find all 4 wheel speed sensors and shows what pins they go to and plugs etc

all good, a helpful forum member sent me exactly what I needed

however, best I don't post it due to copyright, etc.

please tell me you still have this, I've been looking for this in english for more than 10 years, to fix my abs.

are you able to email it? I sent my email address to you.

I fixed my ABS. I didn't get the schematics from here but if anyone needs it, I have it, it covers all the electrical systems for R33.
