elm pro 327 vs picasso2003

sven1973 · 02-07-2007, 03:01 AM

Hello,
I connected my elmtester pro 327 on a citroen berlingo 19d – 2002

Everything went well and i could read the error codes.
When i try to do the same on a citroen xsara picasso 2.0hdi 2003, he is not recognised.

Normally it's an obd2 compatible car.
Does anyone has some experience with this.
With hyperterminal he doesn't recognise the codes i'm typing

Maybe I have to manipulate something on startup ?

Thank you
Sven

Are you the Sven1973 from youtbe.com?

What responses are you getting from the ELM on the commands you are entering through hyperterminal? If you post a sample session, might be able to help you out more.

Hi Sven

I have a UK spec Citroen Picasso 2.0 HDi (2001).

I connect to it using an Elm323 with no problems at all. I can confirm that your car is most definitely OBDII compliant.

Hope this helps,

PJ

Hi Sven,

I use an Elm 323 based interface from www.espautomotive.com. They no longer sell the exact model. I connect to my CarPC using a serial to USB converter.

The Elm 323 only supports connections at 9600 baud, which is therefore what I use (the 327 also supports 38400) and the car uses the ISO protocol.

I use the OBD package I got with my scanner (scanmaster) and also the built in OBDII that comes bundled with Centrafuse.

I had to push the connector on quite hard to get a reliable connection on the picasso and move some of the power cables from the fuse box as they seemed to interfere, and make me keep dropping my connection.

Let me know if I can help further

PJ

Using the 323 chip only 9600 baud was possible. Baud rate on the ELM should have no affect on communication. If you can talk to one vehicle, you should be able to talk to second vehicle with the same settings. If you provide more details on the exact response coming from the vehicle I am sure I can help.

With hyperterminal on the berlingo (because i tested it on a car that fonctions)
elm327 v1.1
(type) atz(enter)

elm327 v1.1

(type) 0100(enter)

codes (numbers) i diden't put them on paper because the obd2 is working
type 011c(ent)

numbers

type 0101(enter)

numbers ............
...........

when i do the same with the picasso
i get

ELm327 v1.1

(type ) atz(enter

elm327 v1.1

type 0100 (enter)

......
.........
NOT RECOGNISED

??????????????????????????

That is very interesting and appears to be an error within the ELM. I have looked over the ELM327 spec and see no mention of that response even being possible (It is interesting to me that you spelled recognize as recognise as well ~ used more in Britain) did it actually spell it that way or were you writing from your memory?

You can view the spec here:

http://www.elmelectronics.com/DSheets/ELM327DS.pdf

It could also be you are not actually using an ELM chip, but an emulated chip ~ or perhaps it is using the ELM327 chip, but I do not believe that response is coming from the ELM chip. I do not know how else it would be possible to receive responses that were not in the spec (Unless ELM purposesly did not publish such possibilities). I would contact ELM electronics directly or the company you received your interface from. If you tell me where you purchased the interface from it might also provide a few clues to the issue.

edit: You will notize the ELM documentation uses the word "recognize" a few times. I find this odd that the chip would reply with "recognise" ~ maybe I am reading into this too much (ELM Electronics is from Canada and who knows where the guy who programmed the chip was from), but if you take that into consideration with the fact that the response is undocumented... Something does not add up.

if you want the exact replies i can give them this weekend if you want

i bouth it from a german site

I found a post here where you state that the response is "UNABLE TO CONNECT". You have to realize when you are looking for help on something like this you have to be extremely clear, certain responses have specific meanings.

What this means is the ELM chip has cycled through all the protocols and was unable to find an ELM327 supported protocol. They suggest you make sure your ignition key is on as well (obviously this can not be your problem). I am confident at this point your vehicle will not work with this chip, but you will need to contact ELM Electronics for exact reasons why.

I know very little about this vehicle, is it a diesel? Perhaps this is a J1939 supported vehicle? Someone else might have more insight on this.

michbound · 02-08-2007, 01:40 PM

I wonder if somehow the chip got into a specific protocol.

try setting the protocol to auto and then issue the command.

so type ATSP0 then hit enter

And then send it the 0100

digimotojoel · 02-08-2007, 01:47 PM

That's a good thought Paul. However, the docs state that if the chip attempted to connect to a protocol other then the currently defaulted protocol (if not on automatic search) it would reply with a BUS INIT error. Definitely worth a try though.

sven1973 · 02-09-2007, 11:09 AM

Joel,
I'm sorry for the UNABLE TO CONNECT, i read a lot of things that at the end you don't know what you saw.

Now,
Hyperterminal;
baud rate 38400
yes - terminal keys
emulation - auto detect
telnet terminal id - ansi
buffer lines 500

ASCII setup
ASCII sending (nothing yes)
ASCII receiving
yes - append line feeds to incoming line ends
no - force incoming data to 7 bit
yes - wrap lines that exceed terminal widh.

CONTACT ON

(H = hyperterminal - E = enter - T = what i type)
H = Elm327 v1.1
T= atz E
H= Elm327 v1.1
T= 0100 E
H= searching......
H= unable to connect
T=011c E
H= searching........
H= unable to connect.
....

Paul,
I restarted the hyperterminal and
H= elm327 v1.1
T= ATSPO E
H= ?
T= 0100 E
H= searching...... unable to connect

Scantool 1.13:
options
metric
com2 (obd)
38400 (baud r)

startup
reseting......(that was quick)
waiting ecu timeout...
detecting obd
protocol could not be detected
please check connection to the vehicle and........ignition is on.

By the way, thank you for youre time

Sven
