OBD compliant ECU

Does anyone know if the Mazda 323F BA has an OBD II compliant ECU?

Whats the VIN :?:

By OBD2, do you mean giving 4 digit P codes and being able to monitor/simulate PCM outputs/inputs :?:

Is "one of those" a learning ECU?

(takes back to other argument!)

OBD2 is that a friend of R2D2 (starwars)

Sorry lads couldn't help it, anyways back to the topic :lol:

i would also like to know the answer to this question. You can buy kit like this

ISO OBD2 diagnostic interface USB

and plug it into your car and a laptop to show you loads of settings and I think this would be really handy, if not cool.

If they are not obd2 compliant, then what DOES fit into that diagnostics plug under the bonnet?

It is a diagnostics port interface standard. I believe European cars after a certain age (can't remeber, but think it was about '96/'97) should have them by law.

I kinda answered my own question I think. If theres a port inside the car on the driver's side (visible from a crouched position with the driver's door open), then it's OBD2 compliant. It will also mention OBD(I or II) on the VIN plate somewhere.

I wanted to know because, as Adam pointed to, I wanted to connect my Palmtop up to it to display various info (RPM, throttle position, air intake pressure, exhaust oxygen content, speed, temp, etc). Not for any particular purpose at the moment - just thought it would be nice.

I've got a little black thingy just behind the main fusebox in the engine bay with "Diagnostics" written on it. Lift the lid and there's a socket thhere with about 20 connections - I suspect that may be it ???

No, pretty sure it's the wrong sort of connector - I have one as well. The OBD standard specifies the connector and roughly where it should be.

Well the one Smotter is on about is the one i saw too. can anything be connected to this as I am fearing that our cars are not OBD compliant.

I want my laptop connected!

Later 323F's (can't remeber the VIN change point) have a serial port connector in the 18 pin connector under the bonnet. This is not a "standard plug". You can monitor PCM outputs/inputs from this with the right equipment. Mazda dealers have the NGS (New Generation Star) or WDS (Worldwide Diagnostic System) for this purpose

Which are hand held testers. Don't get this system confused with EOBD or EURO3 systems which have the 17 pin connector under the dash. Mazda have only used this since about 2001, so only on late BJ models

I'll see if I can get hold of and bring an NGS along to the Bury meet for a bit of a play if you like

That would be good to see Robbie. It would also be nice what Mazda do to charge £40 for "re-setting the ECU"?!
