JOBD on Japanese models?

[Yousuf Khan]

Hi, sorry for the slightly off-topic here, I asked on the Toyota
newsgroup, but it seems to be a newsgroup in turmoil (off-topic
outnumbers on-topic). I'm currently in a country which gets a lot of
used right-hand-drive Toyotas straight from Japan. I have my OBD-II
connector plug for my laptop with me, and I was about to try to read the
codes from a '98 Corolla, when I found out that these models don't have
a JOBD port. Later I found that some 2004 models of cars had these
connector ports. So does anyone know when these ports became standard on
Japanese-model cars? In North America, they became standard after the
1996 model year.

My only suggestions involve where I would start my research. I'd
probably try to email the guys at www.troublecodes.net with my
question. Hoping that they knew of a way to force a 'blink code' or
maybe one of their 'link partners' that deal with reading systems
other than OBDII.

I would also post the question at NASIOC and at www.ultimatesubaru.org
..

Maybe the Australians get the same vehicles you are getting? Search
for folks building sandrails - some Aussies build them with soob
parts.

good luck

yeah, definitely try contacting some folks at these links;

Could somebody explain what the acronym "JOBD" means and what it is?
Thanks!

Hi Catherine!

In the US, we have cars with OBD-II. That stands for On-Board
Diagnostics (version 2 ?); a standard that allows external devices
such as a laptop to communicate with the car's computer(s) for
diagnostic purposes, and to get real-time engine and other auto
systems performance data. Very useful for many applications.

Visit these guys for more than you ever wanted to know on the subject:
http://www.obdii.com/ http://www.scantool.net/

I'm guessing, but JOBD is probably something like "Japanese" On-Board
Diagnostics. I'd guess the major differences are the character sets
involved (ASCII vs Kangi ((whatever it's called; Japanese writing)),
but don;t take that as an authoritative answer.

ByeBye! S.

I bet you guessed right, but I hope somebody who speaks Japanese and is
familiar with Japanese car stuff can confirm this. Thanks!

The common term used here is JDM (Japanese Domestic Model). A
significantly large proportion of "first time registered in this
country" vehicles are second-hand JDM vehicles. As far as I am aware
OBD readings in KIWI are not a problem. I would imagine that OBD output
would be universal and it is the readers which would interpret the
display to the language of the country.

In North America, the standard is called OBD-II (On-Board Diagnostics
v2). In Europe, the same basic standard is called EOBD (European OBD).
In Japan, it's called JOBD (Japanese OBD). The European and Japanese
versions are pretty much completely compatible with the North American
OBD-II. The only difference I would think are that the Euro or Jap
versions would have some extra problem codes for their own specific
markets. But I can't think of anything that a Japanese or European model
of a car would have that isn't also on a North American model of car.
I'm thinking of emissions related stuff, and what not. Most vehicles
throughout the world these days have similar emissions equipment, but I
suppose the potential is there for the Jap or Euro regulatory bodies to
add a requirement that wouldn't be on a NorAm vehicle at the same time.

Thanks much. I think that I have the idea now. Would a 1999
Forester have anything remotely resembling OBD of any kind? I was
thinking that it might be fun to hook my laptop up to the car and see
what I can see....

Turmoil? Nah, no turmoil. We just have so little to discuss about Toyotas
that we tend to "wander" a little!

As far as OBDII, I thought the port was universal. My '95 Tercel had one,
although it was required until 1997.

Are you in the US? OBD-II was mandated for the US in 1997.
Also, be careful. You can do damage in there! (You can also make the car
run like a bat out of helk, possibly at the expense of emissions
compliance or fuel economy, and possibly engine damage.

Bear in mind an ECU is ~$800...

Hi Catherine, Yousuf, All!

Yousuf, as an example, I know for sure that mid 80's JDM Toyota's
(anyway) didn't have EGR valves. I can imagine where there might be
subtle _other_ differences, even in newer cars, but as you say,
probably nothing that would keep the OBD interface from functioning.
It's generally not cost effective to re-invent the wheel (so to speak)
for every possible market requirement. Rather, you build everything
conceivable in, and selectively disable the pieces you don't
want/need.

But I certainly wouldn't want to offer bets that this is the case

Catherine, to connect to your laptop, you need an interface module,
and appropriate software. Hit that "Scantools" link for an idea of
what's involved. I have been using one of the original Elmscan modules
for several years with great results, but I'm sure there are other
perfectly good packages out there. The basic software is included
(with the Elmscan), but again there are numerous selections; some
freeware, some shareware, some commercial. And you don't necessarily
get what you pay for, either.

Email me directly if you want more info on this.

ByeBye! S.

Yes, I am in the U.S., and the Forester that I own isn't greymarket. So
I guess that answers that question.

Also, be careful. You can do damage in there! (You can also make the car
run like a bat out of helk, possibly at the expense of emissions
compliance or fuel economy, and possibly engine damage.

<nod> I gather that any damage that I did would be in reprogramming
things, not just in retrieving the current settings and looking at them.
Right?

Bear in mind an ECU is ~$800...

I already know that -- one had to be replaced on my 1998 Subaru Outback
Sport after a weird air conditioning compressor condition caused the
original one to be soaked and shorted it out. :/

Where's the fun in that?! ;p

Yup, if it's a North American model. Any car from '96 onwards should
have it. If it's a European model, then only cars from 2001 onwards
would have them. If it's a Japanese model, don't know, that was the
subject of the original question, after all.

OBD just reads and/or resets data from the ECU, you can't reprogram the
ECU through any of the OBD interfaces.

That's because yours is a North American-market model. I'm talking about
an actual Japanese-market model (with right-hand drive, and all of that).

Lucky SOB...

Here in the states, we are limited as to what has been "Federalized" to
meet safety standards. I would love to get my hands on one of those little
Suzuki vans; they are sold here as Cushmans but are only to be used for a
closed-campus application like a college or a large company.

But, you guys have a much more rigorous "certification of fitness"
(INSPECTION) than we do; a guy from NZ told me his friend's Corolla failed
because the door hinges were worn!


But you get some pretty cool Jap cars there! I LOVE wonky Jap cars.
(I imagine you also get Holdens and those Ford "Falcon" car style pickup
trucks, too)

Would have to be an 'well used' model for it to have worn the hinges
sufficiently to 'fail'. We have to pass a WOF (Warrant of Fitness)
inspection annually for the first 5 years and then every 6 months. Some
of the requirements are tough. Any rust is looked at critically. Wile we
do have a little snow and ice we don't salt our roads.

But you get some pretty cool Jap cars there! I LOVE wonky Jap cars.

Generally if it's been on the roads in Japan it will be here.
Eventually. (it helps that they drive on the same side of the road)

(I imagine you also get Holdens and those Ford "Falcon" car style pickup
trucks, too)

A few of them around. the Ozzies race them:
