Merged Lexia & Diagbox threads

[Mandrake]

Welcome to the forum, and hopefully your new Lexia can help you unravel the problems you're having. I've only had one for a few days and I've already learnt a lot about it, at least on the Xantia. I'd imagine the Lexia can do a lot more on the C5 as a lot more of the car is computer controlled...

One word of warning though, you can potentially cause serious trouble with a few options. I would steer clear of any options to download software updates into ECUs (as if the download failed the ECU could potentially become an expensive brick) and also avoid performing any initialisation procedures - these are normally only performed at the factory or when ECUs are replaced.

Most other options are safe including fault code reading, fault code clearing, reading live sensor data, and performing actuator tests, which are most of your troubleshooting tools. Some devices also have a configuration option, for example the CPH (body computer) on the Xantia can be configured to enable or disable the alarm and or dead locking.

I would imagine on the C5 there are a lot more configuration options, including setting the ride height and enabling and disabling various accessory features.

If you have any concerns about a certain option or are not sure what the right thing is to do, don't hesitate to post on the forum and ask advice from those who have a few months/years experience under their belts with the Lexia.

Some of us also have access to Citroen service data which gives advice and step by step instructions on how to use the Lexia for certain tasks, such as key/remote programming, so if there is something you think it should be able to do but you don't know how, give us a shout.

Thanks fo the welcome Mandrake. As I am already hitting some brick walls and not sure if its the way the lexia works or that getting the car jump started has spiked some bits, so i will ask some possibly stupid questions.

1/ doing a fault scan it comes up with various fueling problems. When I try to get into the the injection part of the program to view and clear faults the screen just shows a thin bar in the centre of the window i have left it for a minute or two still no action. Does this screen take a long time to come up or am I doing somthing wrong like not having the engine running?

2/ the electric windows do not show a fault but the switch on the drivers window will only wind down and not up. I used to be able to close the window by removing the ignition key the cycling the window switch on the fob but since trying a couple of battery disconnect resets to try and correct the problem that has stopped working for both front windows (the passenger front still works ok from the door switches though). I tried to customise the options from the lexia but when I wrote to memmory it came back with a memory access fault after the green bars got half way ( about 9-10 mins) three times. Before the current problems the drivers switch sometimes seemed to have a mind of its own and as it has not raised a fault code that perhaps the switch or the front end of the circuit board has a dud flipflop chip on it. is there a way to raise and lower the windows in the lexia program as each time I try it I have to take the door panel off and remove the motor so I can push the window back up. I am beggining to think about putting a manual winder on it.

any opinons are welcome

Cheers Phil D

You may get more response if you post a new thread in the forum regarding your problems - this is a long running sticky thread regarding group buys for Lexia's so I imagine that most people that already have Lexia's would pass this thread over and not keep up to date with it.

I would have thought that connecting to the ECU wouldn't take any more than about 20 seconds, if its the engine ECU try turning off the key and back on again then hit enter to retry. If you're connecting to it manually through individual test make sure you're selecting the right type of engine management system. (Use the global test to find what it is first)

Regarding the electric window controls - the Xantia doesn't have an ECU for the electric windows that the Lexia can talk to, but assuming the C5 does you're unlikely to see a fault code logged for an individual direction button not working - you need to find the live sensor data where it will show you which buttons are pressed in real time. Regarding operating the window - see if the window ECU has an actuator test mode.

Hopefully if you post a new thread a C5 owner will respond as it sounds like most of what you're asking is different from the Xantia, which is where my Lexia experience lies so far.

The actual triggers for the windows on the C5 switch are very flimsy, I found that my passenger window went down ok but wouldn't come back up, the switch trigger instead of operating was just flexing where the plastic had split. I bought a second hand switch assembly off Ebay for a fiver.
I took the trigger out of the damaged one and glued it back together with hard plastic adhesive and it's on the shelf now as a spare.

If you go for a second hand switch there's no need to worry about the colour of the frame, you can use the original one, they just clip on.

If the engine is an HDi then you'll generally be very fortunate to get it to connect within a minute or two when accessing an HDi ecu I set Lexia running then walk off to do something more important/less boring than looking at a frozen screen and return after at least 5 minutes.

Thanks for the replies Gents most helpfull. I am always wary about getting to know a new system as they all have there own flow. I know it seems daft talking about logical systems this way but a little bit of frustration at the wrong time can rearly cause that OH ___T moment. I worked in IBM/Microsoft systems since 1983 and now when a new operating system from them comes, once you get past the new bells and whistles, you already have a feel for the system.

This is the first time I have used OBD diags and without the manual I feel like I am walking around the menu system with a blindfold on and I am very thankfull for any tips on its operation I can get.

Cheers

I've been having a play with Diagbox on my C5 X7 and have come across one menu called "Bashe 5" Diagbox states "Communication Error" with this item, nothing appears to be wrong with the car as such and looking on the pictorial diagrams Bashe 5 doesn't appear, I'm just curious to know what it is/stands for.

Bloody Awful System of Horrifying Electronics? Version 5 (the others weren't bad enough!)

Sorry, I sometimes come up with silly meanings for acronyms. I am sure somebody will come up with a better answer.

Sounds fair enough to me

[Mandrake]

So Diagbox as supplied by easy diagnostics does work fine on your C5 X7 then ? If so that's good to know. I assume you installed both sets of updates even though the printed procedure didn't mention the second one ?

Yes it does, the amount of info available and places you can go exploring is enormous, I updated it via Diagbox and the main Citroen server, worked a treat, IIRC I'm now working on 6.24. When Diagbox does a global search on the C5 an "Authentification" box appears several times but clear that and the following ones and you have access to info beyond your wildest expectation.

As per the thread title one item that is listed on the global test is this BASHE 5, I can't see what it does or find any reference to it either in the pictorial menu of Diagbox or in a Google search, I'm just curious.

Has it told you the answer to life, the universe and everything yet Richard?

Oh yes you'd be in your element with this Jim

Richard, I'd be like a kid in a sweet shop I must come down and have a look at this incredible machine of yours...

[Mandrake]

Interesting, I'm still on 6.22. How did you do the internet update, is there a special procedure ? I didn't see anything about it in the notes supplied, in fact the notes say to make sure an internet connection is not active when running diagbox...(presumably to prevent diagbox talking to the real servers, instead of the fake ones that are running on localhost...)
