Dealer diagnostic scanner for comprehensive Citroen and Peugeot cars diagnostic. You can do all as the authorized dealers do. This diagnostic software allows you to perform complete diagnostics of all Citroen and Peugeot cars from 1995 till present models. Diagnostics is performed via OBD-II connector (which is located near steering wheel) or via manufacturer-specific connector (only older cars, pre-year 2001).

Supported Functions: Unlike other universal car scanner tools which only read fault codes, this software performs nearly ALL the functions like the original dealer diagnostic tool. Our diagnostic interface contains K-Line multiplexor, CAN-BUS interfaces and SAE J1850 bus (both PWM and VPW).

The following diagnostic functions are supported:

- Read identification
Displays complete identification of control unit, e.g. part number, software/hardware version, manufacturer, etc...

- Read fault codes
Displays all stored and pending fault codes with complete description (e.g. "Rail pressure - too low pressure"). Program supports report printing or copy to clipboard.

- Clear fault codes
This function clears all stored fault codes and other diagnostic information.

- Auto-scan (complete car scan/test)
Detects all ECUs (electronic control units) installed in car and reads all diagnostic fault codes.

- Measured Values
Program displays live Data like Engine Speed, Battery voltage, Oxygen Sensor, Coolant Temperature, etc. Values can be displayed in graph, 9 values at once, or full listing (all measured values). Logging to file is also supported, which allows offline analysis.

- Actuator test
Actuator test activates particular actuator (e.g. turn on fuel pump, lock/unlock wheel, lock/unlock doors, cut off fuel, etc...)

- Programming functions/Adaptation
This feature is of great importance in all vehicles because systems like Engine control units, Immobilizers, Airbags, Alarms, Body Control Units, and some others, require you to perform reset or programming procedures after car repair is done, or even configuration after replacing broken Control Unit.

- Hardware and software requirements
Software requires at least Intel Celeron/Pentium III 400 MHz, 128 MB RAM, 50MB free HDD space and USB 1.1 port (USB 2.0 recommended) and Microsoft Windows 98 SR2/2000/XP ++++NOT VISTA OR 7++++++

If that give me all the ECU data and in realtime to a laptop - wow!

Yes, that is a Lexia 3, that one looks to come with a 30 pin adapter which is good! You would be stuck without that adapter! There were cheaper Lexias on ebay a while back so it might be worth a bit more searching. Make sure it actually states that it comes with a 30 pin lead, don't take the photos as gospel.

What sort of 1995 Xantia have you got? Fortunately, the only ECU in my late-95 (built Jan 96) 1.9TDsx is the ABS ECU and the usual fault code from that, "Faulty x/S/x sensor" is misleading - the fault has always been a dirty connection NOT a failure of an expensive sensor .
