JZZ30 ECU Pinouts (Urgent)
|

Does anyone know the pinouts for the JZZ30 ECU ?
Mine has the 4 plugs (34P, 22P, 16P, 28P) in the back of it (Part # 89661-24281).
I urgently need to find out how to extract the check engine / error codes out of it as I am having a troublesome  misfire issue.
Thanks 
Ash

You legend Peewee ! 
I've been searching for that for sooooo long.
Does this sound right :
So if I connect my test lamp to 12V at one end and "W" terminal at the other, then I should be able to get my error codes from the test lamp ?

Yes, W goes to ground inside the ECU

No luck.
I tried to get the code straight out of the ecu, but couldn't get the lamp to blink once.
Does anyone know of another way to get the error codes ?

Turn the key ON, with the jumper not in there.
The light should be ON constant.
If its not, then the motor is not at rest.
Most likely the TPS is not at IDL

Sounds like a reasonable explanation peewee.
How can I test/check that ?
Thanks

Can anyone confirm the terminals' and readings you should get when testing a 1JZGTE TPS ?

Play around with the TPS and a multimeter.
Its only 4 pins, work it out.
You can't blow it up.

I have the uncanny ability to blow stuff up with the greatest of ease.
I enjoy working on cars myself, but I do worry about doing the wrong thing and making more problems.
