According to lexia it detects this ecu model...but why?

I will continue to experiment... :oops:

Do you have access to Diagbox? This might "see" the system differently even if all it does is to launch its own internal version of Lexia!
Hi
I think I have the beginning of an answer and it goes in your direction!
I also thought old car equals old lexia...
Apparently not to recognize this calculator written in 2002 you need diagbox 5.02

I hope this 3rd installation will work

The "?" at the injection ECU is unimportant - the control unit is recognised and can of course be called up.
The error query can then be used to determine further.

Hi

precisely it gives me the message that the ECU is not recognized and that the information cannot be guaranteed.

In the previous message I show what he thinks he recognizes is it's a ecu that exists but not my model.

I'll try to make a video maybe it's more telling

THANKS

Hi

I reinstalled lexia 3.47 and this time it "works"
-He offers me some more model
-all dialogue is yes with no "?'
-he no lets me choose my ecu from the list, he chooses sp2000pm1, telling me this time that it corresponds to my vehicle.
-it only reads stft (the ltft is unavailable)
-data recording still does not work, it remains blocked. "Please wait"

I downloaded diagbox I will also test...

If installing Diagbox, Version 7, upgrade to at least V7.58 as I know there was some issues with the S2000PM1 on the C3 on versions earlier than this.

Hi
I installed diagbox 7.02 with the hope of being able to log.

The communication not doing so I used the application provided with "PSA interface checker" it is explained there that it is necessary to update to use diagbox.

It is written to activate then select a first file "appli" then download the flash app.

Then install the second file "vci updater"
problem I have no more communication after the first flash.

The tool flashes 3 times and stays green but psa checker is no longer connected..

So I deleted diagbox and put lexia back but lexia doesn't work now "no vci"...

Should I throw the interface in the trash?

Hi

I managed to get my interface working again.
I returned to the starting point.

I can not:
- do live data
-read stft ltft
neither reset adaptation
like in this video
(I have not this option in lexia)

Your interface probably has missing hardware so cannot communicate with certain ECUs on the CAN network. You need a Revision C with all the hardware for these vehicles. Cheaper clones are cheap for a reason - they are missing hardware, but were OK for older vehicles.

1. the video shows a Diagbox 9.68 VM and a very specific C5 R - each Citroen model has different intervention possibilities because there are different control units. The video is only valid for this specific vehicle type.

2. the LEXIA present in the 9.68 VM has mostly identical applications as the old LEXIA 3 - but sometimes less.

3. you probably still have an older VCI, which only works up to firmware 4.2.2 and therefore cannot be used with the V07.xx and certainly not with a V09.xx. Sometimes the VCI can be reflashed - but rarely does it work perfectly and it does not always survive the intervention.

4. any DIAGBOX can be used but for all old Citroen vehicles up to approx. 2009 the DIAGBOX is not necessary - the old LEXIA 3 is mostly optimal and also the older VCI can be used.

If possible, the old LEXIA should be updated up to ..348 (347.99).

If you think you can reach your goal with a higher software version, you will probably need a newer VCI with a corresponding laptop.
I understand a large part of your experiments only rudimentarily - but practice makes perfect.

Hi

The idea was to use lexia to do diag and live data.

The goal was to first find out why the car is idling weirdly.

Finally it's a little cheap Obd bluetooth and a free software that allowed me to start the diag with trims +15% on 98 gasoline.

And then make logs to change the injector of tu5jp4 to switch to ethanol.

I'll find out what I have as hardware and if it can be updated...

I thought diagbox would be more modern, especially for live data.

Finally lexia does not allow me to do anything except diag and live data it does not even recognize the correct ecu and the live data crashes "please wait"
yet it is the old tool for an old car.

I still find it strange that it is less efficient than a standard Obd...

For the moment my tests with diagbox do not work.
(I must be about 10 years old trying to install different versions)

Thx all

Hi

Apparently I'm already in C.

The DIAGBOX is not more modern, but it contains 3 software packages.
The old LEXIA for Citroen until approx. 2007
the old Planet for Peugeot until approx. 2007
and all newer PSA vehicles (also Opel) depending on the software version up to current.

For a Citroen vehicle before 2008, it is possible to start via the DB interface - but a diagnosis is only possible in the LEXIA 3 contained in the DB.

Depending on the software version, appropriate PC constellations are required and the software must be installed and used.

There are also conditions attached to the quality of the interface (VCI) - and many China clones are overwhelmed and no longer work with the DB.

Your VCI is probably a China clone, which - as I understand it - works with the old LEXIA 3 - why don't you just leave it at that.

I myself use the old LEXIA 348 - the DB 7.57 - the DB 9.68 VM and the DB 9.96 with original VCI. All ECUs are recognised and of course all offline work can be carried out in all ECUs - not only in the injection control unit - component tests//parameter measurements//reading out/clearing errors/etc.
And more is apparently less for you, because you want to diagnose an old car with a senseless higher software, at which your VCI drops out.
The old LEXIA 347 and yet it works???

and just to add... the Revision 'C' reported via the interface checker doesn't necessarily mean it is actually a revision C unit or has all the hardware.
