Xac, thanks for posting the Utube videos of Stealth. Did you see the videos of the "rollbacks"? I was so hoping it would do a rollback or two yesterday. It seemed to cone very close to it a few times!
Great to hear you are now the proud owner of a Lexia Superloopy
The question of dual-booting a Lexia 2 so that it can also be a DIAG2000 has been raised before and I'm not sure if it can be done in a satisfactory way. The basic operating system is embedded XP and thus the boot.ini file couuld be modified to dual boot from two partitions but already the hard disk is split into two partitions and the partition names may cause problems when running both. Also, the firmware "knows" if the personality of the machine is Peugeot or Citroen. When Malcolms had a personality change, it did quite a lengthy firmware update. I'm not sure what would happen if you tried to revert it back to a DIAG2000.
I have DIAG2000 hard disk in my posession but I've not yet had a chance to look at it to investigate the structure of it. This weekend I'll have a look into it if the SWMBO's allow me to have some playtime
The recovery CD is CD No.1 and is called the Evolution CD. You invoke the recovery process by inserting the CD into the drive and holding down the validate key whilst you turn it on until it bleeps furiously and a small menu appears on-screen. It then launches Ghost to install the OS. Then it asks for an update CD to install the Lexia Applications. On the subject of update CDs, My latest is CD37 and I thought it was the last one. Interesting you have CD39. The restore process takes a long time and it's a lot quicker to build and fit a new hard disk from a previously taken ghost image using a normal PC.
Cables. There are a plethora but only a few are essential. Those are the 37 way D to the 30 pin diagnostic connector (for pre '98 cars), the 37 way to 16 pin EOBD for later cars, the power cable to run the portable from a 12V supply which should end in bananna plugs to enable a cigar lighter adaptor or croc clips to be fitted and the test probes that end in 15 pin D plugs for using the oscilloscope and multimeter functions. Other leads will be for the modem, printer and Automatic Harness Tester but unless you have the breakout boxes to go with them, they will be of little or no use. I have leads I have not a clue as to their use
All Lexias I've seen have been very dirty after years in a garage environment. They clean up well using foaming cleaner spray.
Play with it to see what it will do and how to use/interpret it but in a nutshell, it can diagnose and access all ECUs on a given Citroen so on your Activa you'll be able to look into your Engine ECU, Hydractive ECU, Airbag ECU, Aircon ECU, ABS ECU and if a MKII, you should be able to get into your alarm ECU and on automatics, into the Gearbox ECU.
Stored faults can be read, diagnosed and cleared.
You can also use it as a pretty full-featured multimeter and oscilloscope, read wiring diagrams on the screen if you have the wiring diagram CD's (I have an incomplete set and I don't have CD1 which covers the Xantia

) You can download software updates to ECUs and on MKIIs you can recode keys. It also works as an EOBD tester for EOBD compliant cars.
The only way to get au-fait with it is to play with it. You need to know the RP number of the car you want to daignose and the engine and engine ECU codes. So an Activa will have the RGX engine and MP3.2 ECU. Conversely on a 1.9TD it'll be the DHX Engine and Bosch VP20 ECU (IIRC?) You have to tell Lexia this but everything else it figures out for itself from the RP number. When looking at the Hydractive ECU you need to tell it if you are looking at an Activa.
It's slow to read the ECUs because of the low data rate and you can ignore the prompt about turning the ignition on and off when initially interrogating an ECU. Just push the validate (*) button.
With a running engine, you can read live data from it and also, if you go for a drive with the Lexia running, you can watch the hydracttive suspension switching in resopnse to cornering etc. If you really want to watch it live, travel as a passenger as driving and Lexia watching is a tad dangerous...
The battery won't hold it for long. Just long enough to move the portable off the trolley and into the car and get it running from the cigar lighter. If you are running from the cigar lighter and go to start the engine, the Lexia will reboot as power to the lighter is cut when cranking. When running from the lighter socket, the internal battery is disconnected

and will not prevent this power-loss reboot. The battery will also only charge when powered from the trolley supply. It's charging when the green light is on and fully charged when it goes off. If the portable is running on internal battery, the battery light goes red when it's about to run out. The battery is a standard Acer laptop battery.
Lexias take an age to boot. perfectly normal.
Charge your Activa battery off the car and make sure it is fully charged before trying to start. A low battery makes the tacho needle spin around full-scale and jam against the end-stop requiring some work to get the needle back to zero. The alarm will go off when you reconnect the battery but it's easily reset with either the plip or by holding down the ultrasonic defeat switch whilst turning on the ignition.
Tells us how may faults are recorded on your cars. Your Activa is bound to have Hydractive faults recorded!
Any Lexia questions that crop up, give me a shout!
