JOBD on Japanese models?
Yousuf Khan
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 involves 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.
yeah, definitely try contacting some folks at these links;

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.

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...

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.

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

<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?

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. :/

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).

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)
bugalugs
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.

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)

A few of them around. the Ozzies race them:

Over here it's regulated by the state. I live in Mass, and rust is frowned
upon. And we DO use salt! Kills Japanese cars. In the next state up (New
Hampsire) they either don't bother or tell you to put some Duct Tape over
it, something that ended in Mass about 15 years ago...

Yeah, that'd be them! They used to sell them here, Ranchero by Ford and El
Camino by Chevy. Like the Oz counterparts, they were based on some pretty
hot cars, especially at the end (~ mid-80's). They were kinda cool, but
the mini pickups (Chevy LUV and Ford Ranger) killed them off.
The other day I saw one, a custom job made from a '53 Mercury! (NOT a
factory job! ;)
Yousuf Khan
Just an update. I found out later that even 2001 model JDM vehicles had
the JOBD plugs, so it looks like JOBD and EOBD came online at around the
same time, 2001.

JOBD is definitedly design for Japanese vehicle. As there is OBDII for
america, EOBD for eroupe. Japanese vehicle has their own special protocol. So
they develope their own communication protocol for their car.

propocol - if what you say is true Subaru has to make a minimum of 3
different versions of every computer - and possibly different
harnesses as well?
Yousuf Khan
or less. Maybe a few unusual codes are different between them, but the
basics are the same.
Yousuf Khan
cl...@snyder.on.ca
using the same SAE J1962 pinout and connector. Only the actual
"regulation" has any appreciable difference. Within the OBD2 standard
there are 5 different "protocols" used.
Each protocol uyses a different pulse train - with different
frequencies and coding.
SAE J1850 PWM (pulse-width modulation - 41.6 kbit/s,) is the standard
of the Ford Motor Company.
SAE J1850 VPW (variable pulse width — 10.4 kbit/s) is the standard of
General Motors
ISO 9141-2 .(This protocol has an asynchronous serial data rate of
10.4 kbit/s. It is somewhat similar to RS-232; however, the signal
levels are different, and communications happens on a single,
bidirectional line without additional handshake signals.)
ISO 9141-2 is primarily used in Chrysler, European, and Asian
vehicles
ISO 14230 KWP2000 (Keyword Protocol 2000)
I'm not sure how this one works or who, if anybody, currently
implements it.
ISO 15765 CAN (250 kbit/s or 500 kbit/s). The CAN protocol was
developed by Bosch for automotive and industrial controllers. Unlike
other OBD protocols, variants are widely used outside of the
automotive industry. While it did not meet the OBD-II requirements for
U.S. vehicles prior to 2003, as of 2008 all vehicles sold in the US
are required to implement CAN as one of their signaling protocols. It
is used in conjunction with one or the other of the standard prorocols
on most current vehicles.
Your scanner can tell which protocol to use by a combination of which
pins are used and the frequency and/or voltage on the pins..
On top of the mandated OBD2 standard, many manufacturers supply a lot
of other data from other systems on the car through the OBD port using
a "standard" or "protocol" called EOBD2 - which is not "European" but
"enhanced".
Some EOBD2 codes can be read by some basic OBD2 scanners, with
better/later scanners also able to read CAN bus codes , and the higher
end units capable of reading the EOBD2 codes of MOST manufacturers. No
manufacturer is "required" to make their codes available on generic
code readers and some may choose to require specific diagnostic
equipment to access these codes.
