Description - AIR CONDITIONING - Fiat ULYSSE 2.2 16V JTD fino a 04/03

The vehicle is equipped with a climate control system for managing the temperature, air flow rate, distribution and recirculation.The control unit manages the operation of the system by controlling:air temperature at the vents;air distribution at the vents;fan speed (continuous variation);compressor engagement (air refrigeration circuit);air recirculation engagement.The system controls are located on the outside of the container which houses the control unit: the following parameters/functions can be controlled manually:fan speed;distribution arrangement;compressor enablement;defrosting/demisting:recirculation.

Operational Description - AIR CONDITIONING - Fiat ULYSSE 2.2 16V JTD fino a 04/03

Climate control unit M070 receives a supply direct from the battery at pin 11, connector A from body computer node M001, pin 7 connector D from the line protected by fuse F12 and managed by a specific relay, contained inside the control unit.It receives an ingition-operated power supply at pin 12 connector A, from the body computer node M001, from pin 6 connector F, from a line protected by fuse F18.Pin 16 of connector A is earthedControl unit M070 communicates from pins 8, 14, 15 via the CAN with the body computer node M001 at pins 6, 8, 10 connector D and with instrument panel E050 at pins 23, 17, 13 (for more details.Passenger compartment air fan N085 is controlled by selector unit H081. The unit contains an internal control unit that controls passenger compartment speeds according to the speed set on the appropriate selector.The relay J035 supplies the selector unit H081, at pin B connector A, on the go ahead of the body computer node M001, from pin 40 connector M, providing a direct battery supply at the selector H091, via the line protected by fuse MF08 for the engine compartment junction unit B001 (pin 8 connector G).The selector H081, connector B, is then operated by the control unit M070, from pin 2 of connector B, according to the strategy for implementing the management of the internal ventilation.Pins 6, 5, and 4 connector B of electronic control unit M070 supply the electric motors for recirculation N082, mixing N081, distribution N080 at pins 1. Pins 3, 4, 5, 6 connector C of control unit M070 receive the anglar opening position of the internal air intake flaps.Control unit M070 also communicates certain information (heated rear windscreen on, air conditioning on) from pins 1, 2, 3 to the instrument panel E050 to pins 5, 9 and 2 and from there to the various displays [EL4010]. The diesel version signal reaches pin 10 of the instrument panel E050 from pin 18 connector A of M070.
