unable to connect DDT4all correctly

[Chnord59]

Hy guys,

I try to connect DDT4ALL (last release) under windows 10 in BT mode with an ELM 327 CHIP PIC18F25K80). It seems to work but when I try to write in expert mode, nothing happens. The messages are :

Initialisation ELM a la vitesse 115200... Tentative d'ouverture du portCOM7 @ 115200 V├®rfication vitesse de port: 38400 Vitesse port communication : 38400 1581 ECU charg├®es en base de donn├®e. RadNav v1.5 Audio QLayout: Cannot add null widget to QHBoxLayout/ QLayout: Cannot add null widget to QHBoxLayout/

and in the window at the bottom of the screen :

UCE utilise diagnostic session 1003 Envoie requête :StartDiagnosticSession.Extended Delay 0 ms Changement de mode session 10 03 Envoie requête :DataWrite.RadNav Configuration 1.1 Requête abandonée (verifiez les parametres en rouges): NO DATA

Any idea to fix that problem ?

To go on : here are the errors when I start test ELM

Tentative d'ouverture du portCOM7 @ 115200 V├®rfication vitesse de port: 38400 Vitesse port communication : 38400 Traceback (most recent call last): File ".\ddt4all.py", line 1201, in check_elm res = elm.elm_checker(port, speed, self.logview, core.QCoreApplication) File "C:\Program Files (x86)\ddt4all\elm.py", line 1333, in elm_checker print cm[2] + " " + res.strip() File "C:\Program Files (x86)\ddt4all\Python27\lib\codecs.py", line 369, in write data, consumed = self.encode(object, self.errors) UnicodeDecodeError: 'ascii' codec can't decode byte 0xc0 in position 25: ordinal not in range(128)

Thank you

what year is your Renault car - could it be that the OBD port has security gateway firewall - the later Renaults all have gateway so you cannot change parameters until you unlock gateway with token

ah right I should not think 2016 car blocked by security gateway then - did you do a search for all ECU's in your car with the DDT4ALL magnifying glass first yes? You could also try increasing the CAN timeout to 600ms too and see if that helps

[Chnord59]

I will try How to do to increase the CAN timeout ?

[AndyIreland]

[Chnord59]

Ok thank you I did it Here are the results

[AndyIreland]

what parameters are you specifically trying to change on your car?

does your ECUS show up ok here after searching with the magnifying glass?

and are the read parameters in red or not?

[Chnord59]

I select

[Chnord59]

i select XFB MEGANE IV I try to activate the Race mode

[Chnord59]

Is that the good way to select the car ?

[AndyIreland]

no, did you choose that radnav v1.5 manually? - i would not do that. all those read parameters are in red - I would not try changing any parameters where the read in is red! - you could end up bricking ECU if you not careful

[AndyIreland]

Plus have you got a specially wired up obd2 cable or rewired ELM327 cable so that you can read radio/nav through the OBD2 socket of the car???

[Chnord59]

Yes I choose manually I follow a specific tutorial on the french website "au bon coin du Rlink" I have no specific cable

[KarelSvo]

Show the files elm_ddt and ecu_ddt. Show the link of the used ddt4all version. Radnav transmits on Vehicle Can. No adapter cable necessary.

[Chnord59]

[Chnord59]

where are these two files ?

[Chnord59]

I've no files with ddt extension

[Chnord59]

I have elm.py and elm.pyc and ecu.py and ecu.pyc

[Chnord59]

elm_ecu.zip

[KarelSvo]

ddt4all/logs/elm_ddt ddt4all/logs/ecu_ddt

[Chnord59]

logs.zip

[Chnord59]

good version is here, don't use the previous one logs.zip

[KarelSvo]

Your Elm interface is not suitable for this software.

[Chnord59]

which one can I use ? Where is the error in the files ? Thank you

[AndyIreland]

you have a bluetooth ELM 327 OBD2 with CHIP PIC18F25K80 ? - I would have thought it should be compatible. - unless its got PIC18F25K80 written on the outside or in the listing, but really has not got a PIC18F25K80 - is there any way you can crack open the case and see if there really is a PIC18F25K80 chip on the main circuit board?

[AndyIreland]

I dont know if I would be of any help @Chnord59 - but if you want me to log on remotely to your laptop over the internet while you have the OBD2 plugged into your car and see if anything jumps out at me just let me know.

[Chnord59]

Thank you for your help. Is it possible for you to morrow in the morning ?

[KarelSvo]

To go on : here are the errors when I start test ELM

`>[16:19:11.835]ATZ <[0.914]ATZ ü

OBDII v1.5 ` Your Elm sends a non-ASCII compliant character (ü) in connection with the ATZ command. Therefore the test aborts. You can find the list of commands for testing in the elm.py file after the line cmdb = '''. In order for the test to work with your Elm, you must delete the ATZ test lines and then save the file.

[AndyIreland]

Thank you for your help. Is it possible for you to morrow in the morning ?

tomorrow in the afternoon after 2pm UK time I can do if any good?

[Chnord59]

I've just opened it, it strongly difficult to read but it's a PIC 18F25K80

[Chnord59]

Thank you for your help. Is it possible for you to morrow in the morning ?

tomorrow in the afternoon after 2pm UK time I can do if any good?

OK so 3 pm in France

[Chnord59]

Thank you for your help ! I've just opened the ELM to see the chip inside : it's a PIC18F25K80 like written on the box. I'll see to morrow with Andy Ireland who will take control of my computer while connecting to the ECU.

[AndyIreland]

Yes thats right - if you need me to have a look just let me know. I might not be of any help though, especially if it is an incompatible ELM327 . It is bluetooth adaptor is it?

[Chnord59]

yes bluetooth, and I use Windows 10 The car is a MEGANE year 2016 model 1.6 GT 205 HP

[Chnord59]

Does I need to install PC anywhere ?

[AndyIreland]

anydesk from anydesk .com if OK

[Chnord59]

it's done

[KarelSvo]

I've just opened the ELM to see the chip inside : it's a PIC18F25K80 like written on the box.

I had given you a link where you can see pictures with fake unsuitable PIC18F25K80. The Chinese also fake the writing on the microcontrollers.

These chinese...

[AndyIreland]

amazing they go to all those lengths

[Chnord59]

I just think that i won't be able to connect my PC to the wifi outside of my house. So I will use a phone to create an access in order to connect the PC, but it won't be so fast (4G)

[AndyIreland]

ah it might be ok tethered to your phone. We shall see, if its too bad connection we might have to abort it. but I have done it before with others that have tethered to 4G and it werent too bad

[KarelSvo]

These chinese...

give me your elm.py file to edit.

[Chnord59]

if it doesn't work I'll buy a 30 meters RJ 45 to connect to the box !!

[AndyIreland]

thats another way yep

Replace file and run Elm test.
