Re: Lexia 3 V48 PP2000 V25 Diagbox V6.01 installation

Hello all again and thanks for the support.

Giving this a good go the last few days , determined to get there.

Yes Taffy, we have just discovered that having the Lexia connected to the PC before bootup makes it much better behaved - thanks , a great tip.

Mandrake , everything you have said is true , including the USB port, cause we just bent down and plugged the Lexia in by touch, didn't notice that we picked the top port and not the bottom one.

Here is the progress so far - all done on a PHASE I DW8 Xsara.

Diagbox ,select car, typed in RPO and VIN , unplgged and re-plugged Lexia, then pressed return , Lexia application launched.

Went into replacement parts in lexia

Clicked airbag/seatbelt

Clicked airbag

Switched off ignition and switched it on again

Pressed return

Initialisation of dialogue with ecu in progress

Ecu SAC_AKF validate to continue

Pressed return

Clicked on identification

Read configuration - 100%

Identification screen appears with lots of values filled-in


We click F9 and go all the way back to Diagnosis

Click on Diagnosis

Click on Test by Function

Click on Anti-theft

Click on Passenger Compartment Protection ECU

Switch off Ignition, Switch it on again

Press return

Initialisation of dialogue with ecu in progress

No diagolue with ecu during initialisation, Validate for a new test or press return key

Do it a second time -

Get Ecu CPH_TEXTON validate to continue

Click on Fault reading

Please wait - faults being read

Get -

Intermittent fault - no response from Engine ECU

Intermittent fault - locking failure caused by the right door locking button


We know that last one to be true - we appear to be in at last

However - it is very tempermental - get into airbags one time and not the next.

We can clear faults , check again and no faults reported.

Also , cannot get into engine,

Can get into anti-theft and erase faults.

Also , there seems to be a strange combination of remove 16pin socket from car , on/off ignition etc.

This all seems to tie in with what you say Mandrake about bad connections.

What about that engine ECU though, any ideas ?

Going to try it on the Phase II today, which actually has an Airbag fault.

Hope this topict not only helps us but also some other misfortunates who com along afterwards when trying to set up their own Lexia.

Thanks again

Thought that might be the case... :) once the driver is installed on both ports you can use either, however I would advise that when do the unplug / reconnect before clicking Lexia to always re-insert it in the same port it was in when you launched Diagbox.

Sounds good - the replacement parts section is not normally a section you would go into though, as aside from showing ECU identification its primarily for configuration of options - such as enabling/disabling the alarm, listing or delisting optional features, programming keys etc. Most of the time you'll want to be in the diagnosis section.

The CPH is the alarm/central locking/immobiliser unit. It is permanently powered so is one of the only ECU's you can read while the ignition is turned off, and I have never had any intermittent trouble reading the CPH on mine so this would tend to suggest your cable connection is still a bit iffy.
Click on Fault reading

Please wait - faults being read

Get -

Intermittent fault - no response from Engine ECU
This means the CPH didn't get any immobiliser unlock confirmation back from the engine ECU when the ignition was turned on - this can happen if you turn the key on while the engine ECU is unplugged, or very rarely it might happen for no good reason. As long as it doesn't come back after clearing I wouldn't worry about it.
Intermittent fault - locking failure caused by the right door locking button

We know that last one to be true - we appear to be in at last
All this code means is that central locking of all the doors was interrupted by the drivers door lock not engaging. This could be a fault with the door lock mechanism or the lock switches, but its far more likely that you just tried to lock the doors via the remote fob or the passenger door while the drivers door was ajar (on some cars the siren will bleep when you do this) as the door being open prevents the lock button going down and triggers the other doors to open again and this fault code to be logged.

Again if it doesn't come back again after clearing the code and some use of the car (or you can remember trying to lock the car with the drivers door open) I wouldn't worry about it.

However - it is very tempermental - get into airbags one time and not the next.
I wouldn't worry about that too much, my airbags do the same! Rarely do they respond on first attempt. Same with climate control.
We can clear faults , check again and no faults reported.

Also , cannot get into engine,
What engine do you have ? Some of the diesel engine ECU's can take a very long time to read - the Xantia 2.0HDi ECU takes 2-3 minutes to respond to an attempt to diagnose it while my petrol 3 litre engine ECU just takes a few seconds.

Also silly question - but if its an early Xsara diesel does it actually HAVE an engine ECU ? :lol: The early Xantia 1.9TD's didn't have an engine ECU and were entirely mechanical injection....just checking... :wink:
Can get into anti-theft and erase faults.

Also , there seems to be a strange combination of remove 16pin socket from car , on/off ignition etc.

This all seems to tie in with what you say Mandrake about bad connections.
Yeah I think you have poor connections - as I said try to get hold of some good electrical contact cleaner and spray both the round connector and the OBD-II connector then work them in and out a dozen times each and you may notice a world of difference. The pins could be oxidised, and different pins are used for some groups of ECU's which means a bad connection on a certain pin or pins could prevent communication to some ECU's but not others.

Now that you have some degree of communication, what happens if you go back into global test ? It might be worth taking a screen shot of the ECU list in the global test mode so we can see what ECU's it is attempting to communicate with.

It chooses which make/model of ECU's to attempt to communicate with based on an inbuilt VIN number and RPO database which knows which ECU's were fitted at the factory in every individual car made - hence the importance of entering the VIN and RPO precisely. Make a mistake in either (especially VIN) and it might be looking for a petrol ECU instead of a diesel!

Re: Lexia 3 V48 PP2000 V25 Diagbox V6.01 installation

Post by xsaras4ever »

Great post Mandrake - thanks again.

Yep , after posting last time we thought that the 1.9 DW8 probably doesn't have an engine ECU.

We connected it to our Phase II and we can get into the engine ECU.

Also , and the reason we bought the Lexia, we got into the Airbags on the Phase II (cause the light on the dash is permanently lit) and got "Permanent Fault , Drivers Level 2 Airbag igniter Open circuit"

Clicked on it and got

Fault Code - 1802.
Fault characterisation - Coherence.
Fault type - Remote.

Al least we can maybe begin to fit that now.

The next dilema is - do we begin to install all the updates on the Installation disk - or just be happy with the version we have for a while....Its got Diagbox up to V7.16

This is made up of

7.02 - 7.04 , 7.02 - 7.06, 7.06 - 7.07, 7.07 - 7.08, 7.07 - 7.09, 7.07 - 7.10, 7.07 - 7.11, 7.11 - 7.13, 7.11 - 7.14, 7.11 - 7.15, 7.11 - 7.16 ..

However, we think we will leave it for a while - just happy to be working.

We paid 68.12euros for our kit so we are happy today.

Thanks again to all.

If your car can be read by your Lexia as it is, then you (personally, anyway) don't need to do the updates. However, if you want to help anybody with a current PSA car, you almost certainly will need to install them, as what they (mainly, at least) do is to update the Lexia with the newer vehicle information (such as ECU info, etc.).

For a Xsara and other models of similar age there will be no benefit to updating past 7.02, I would leave well enough alone for the time being now you have it working :wink: Diagbox 7.02 is less than a year old (6.22 was the latest version when I bought my Lexia a year ago) so only cars made in the last couple of years would need a later version.

As for the air bag fault itself - I have no experience of troubleshooting airbags (I've been lucky to never have to yet) so I would suggest that you start a fresh thread with the topic of the air bag fault to get the most eyes reading your post. People that have solved air bag problems before might not necessarily read a thread regarding Diagbox installation! :)

Morning all.

Thanks again Mandrake and Hell Razor5543. Its quite a relief not to be updating the software.

We have posted a new topic about the Airbag.

Suppose we will leave DocBackup alone for a while too.

Will find some spray for the electrical connections to improve things there too.


Was it you Mandrake that wanted to also get Multi-Diag working with a Lexia ?

If you are going to get some contact cleaner make sure to get the proper stuff (and not something like WD40), as it should produce satisfactory long term results, rather than a quick fix.

Agreed. Not sure why everyone uses WD40 - it's not a contact cleaner. (In fact for most uses its rubbish :wink: )

This is the stuff that I've used for years, available over the counter in hardware stores in NZ but a bit hard to find in the UK:

http://www.lpslabs.com/product-details/560" onclick="window.open(this.href);return false;

As a contact cleaner it is very long lasting (years) because it leaves behind a thin, dry, dust repelling anti oxidising film, unlike alcohol based cleaners that clean but don't provide lasting protection. (Its great for potentiometers too)

This is where I managed to find some in the UK:

https://www.cromwell.co.uk/LPS7271150P" onclick="window.open(this.href);return false;

A can usually lasts me many years :)

Hello again ,

firstly, thanks to you too Taffy, didn't mean to leave you out.

Got some contact cleaner - before we read the posts on which ones to buy - its the 3 in 1 brand, or "3-en-un" here in France.

Though it was a miracle cure as Lexia connected first time - but back to intermittent after that.

Mind you, the 16 pin connector on our Phase 2 Xsara is terrible, its a really loose fit into it and you have to poke 2 fingers behind the block on the car to stop the connector pushing through the plate.

However, after what we have been through, any communication with the car is a glorious triumph.

Not wishing to hijack the thread but as a n00b to Citroens, what is Lexia and Diagbox?

On the Galaxy we own, I use Vagcom and VCDS software on the laptop with a simple lead that plugs into the diagnostic socket. You can then scan the different components and read/clear codes etc.

Is Lexia similar or is it a little more involved? Reading through this post Im seeing hours to install software which wasnt the case for my diagnostic software.....Having said that I did get the Ford/VW software on DVD's which took about an hour to install but then the updates took an absolute age!

vagcom and lexia is just different software fordifferent makes really..lexia is forcitroen peougoet vagcomis for a larger veriety of makes..its the same idea as vagcom same method of gaining access to the car but i think lexia has alot more to it..i think u can use lexia as a scan tool too but im not sure..
someone will come along soon with a much better explanation mate ;)

I came over here from the peugeot forum as they suggested there might be someone here who has diagnostic software and lives in the North Somerset area who can help.
I need the CD changer enabled on a 206 so I can add an auxiliary input, and the dealers want silly money to do it.

If anyone here can help I'd appreciate hearing.
