A/T ECU Pinout (Complete) Series 1 Auto Transmission ECU

[Kitty's VR4]

Ok I have finally completed Auto Transmission ECU Pinout



This is a sample as its to large to format to JPG and use here.

I have attached the complete Pinout in PDF format below.


I need to acknowledge & thank Nat for helping with the translations, Peter Thomson for the awesome macro photo's and Kieran for supplying the Japanese Workshop PDF's.

A couple of things to note; firstly while every care has been taken translating from Japanese Manuals to english, I don't accept any responsibility for any errors or omissions. Until I have completed pinouts for the FL-Series 2 A/T ECU I'm a little concerned about 2 pins on the Auto Transmission ECU Pinout, being Pin19 & Pin51 which according to the Japanese Manuals are not connected, but clearly in the photos they are connected to wires....

I think that this style of format makes it more idiot proof, and am considering re-doing the Engine ECU in the same format using photos may also include extra info such as expected voltage ranges, I think using this format makes it easy to identify correct wires when working in the workshop...


Any comments / criticism's welcomed, so if you want me to change formats, let me know....

this is good work.

i like the format/layout of the information makes it very readable and the pictures of the connector from each side showing the wire colours is a good ides Nice

thanks for all you effort i know this sort of stuff takes a long time to put together, but as i can see well worth it.

Well done! Very Useful info

[Confused]

Excellent - a great asset to the community!

Well done Kitty....these are truly awesome, especially as I believe the TCU has remained something of a mystery.

Interesting highlights:-
Diagnostics connector.
Temperature sensor calibration values! So a cheap voltmeter can be used to read mission temperature: hooray!

Input Axis sensor and Output Axis sensor : I assume the TCU uses these to check the gearbox is doing what it should.

Not questions aimed at you Kitty: what you've done is awesome! These are points for general discussion.

[Kitty's VR4]

All good Steve.... Do you think the engine ECU Pinout would benefit from the same treatment? Might make them more workshop friendly.

I'm not sure and I'll do a little schematic tracing to see if the Axis Sensor's have anything to do with Torque split's with TCU/AYC, - just my shot in the dark to get the discussion ball rolling, if I'm wrong shoot the messenger...lol, but I'll have a go at decyphering the schematics and translating them.

Your bi-linguistic skills are humbling Thank you.

And yes, if you feel like melting your brain translating Schematics you'll only end up more popular

[Davezj]

just out of interest what schematics are you looking at are they from the original Jap manual, or do you have another source.

can you post them up as i find reading schematics are better done first hand, although reading japanese is not something i can do, but schematics speek a thousand words and are quite language independant.

They are directly from original Japanese manual PDF's

Great work, have some more rep.

Are you able to do a pin-out for that stupid connector that attaches the gearbox?

Would be greatly helpful to those doing Auto/Manual conversions! (I still need to wire up the reverse light mechanism )

[bradc]

Heh, I don't have reverse lights in my VR-4 and it has never been asked about at a WOF, I don't think it is a legal requirement.

[GalantOnly]

There's one in member section too...

Sorry Kenneth, haven't been watching the tread (working on other Pinouts - ABS & TCU) I'll try and get that gearbox connector pinout done during the next week

[Kenneth]

Not so worried about WOF, I mainly want them hooked up for safety purposes...

Cheers, much appreciated

Kenneth, the red/green wire from the black selector switch connector is for the reverse light and R light in the dash...

[Kenneth]

Cheers for that I'll take a look at it.

Bringing this up, since we're looking for the torque convertor control pin. Does anyone have any idea which it is. Documentation gives no help on that matter.
