Abstract

A device (1) for the diagnosis of a central unit of an air conditioning system of a vehicle comprises a microprocessor (6) for processing information, a connector (2) for transmitting information from the central unit to said microprocessor (6) and vice versa, a memory (8) in which is located a resident software which serves as an operating system for the device, interfacing means (2, 3), for transferring input/output information from the device (1) to a user, at least one memory bank (9), of the erasable/rewritable type, in which are located communication protocols, each protocol relating to a type of central unit, and a working software to place the device (1) in communication with a central unit according to a corresponding protocol.

Claims

1. Device for the diagnosis of a central unit of an air conditioning system of a vehicle, having:

a microprocessor for processing information;

a connector for transmitting information from the central unit to the microprocessor and vice versa;

a memory where a resident software, which serves as operating system for the device, is located;

interfacing means for transferring input/output information from the device to a user;

Wherein the device comprises at least one memory bank where are located communication protocols, each protocol relating to one type of central unit, and a working software to place the device in communication with a central unit according to a corresponding protocol.

2. Device as claimed in claim 1, wherein said at least one memory bank is of the erasable/rewritable type.

3. Device as claimed in claim 2, wherein the device further comprises means for modifying/updating the content of said at least one memory bank.

4. Device as claimed in claim 3, wherein the means for modifying/updating the content of said at least one memory bank comprise a PC, an updating protocol for said PC and means for transferring data from the PC to the device and vice versa.

5. Device as claimed in claim 4, wherein the device further comprises at least one smart card reader, to remotely enable said means for transferring data from the PC to the device.

6. Device as claimed in claim 1, wherein said interfacing means have a transflective graphic display and a keyboard.

7. Device as claimed in claim 1, wherein said interfacing means enable the user to enter/display information through personalised menus and/or character types.

8. Device as claimed in claim 1, further comprising means for driving the input/output signals from the device 1, through an automatically selected access channel to the central unit.

9. Device as claimed claim 1, having a high speed transmitter, operatively connected to the microprocessor to run high speed communication protocols.

10. Device as claimed claim 1, having at least one parallel interface for connecting the device to external peripherals.

11. Device as claimed claim 1, having at least one serial interface for connecting the device to external peripherals/modems.
