1) press the PTO button;

2) wait at least 0.5 seconds;

3) release the PTO button.

- The PTO will be actuated only if the PTO button is kept depressed for more than 0.5 seconds.

- The PTO button will be ignored until the next 5 seconds have elapsed.

- After such time, if the button is kept depressed for more than 30 seconds, a quick flash will be displayed, and

PTO disengagement and lock will be commanded until the vehicle is switched on again.

3) release the PTO button.

- The operation will be carried out only if the PTO button is kept depressed for more than 0.5 seconds.

- The PTO button will be ignored until the next 5 seconds have elapsed.

• In the event that the power take-off

is not disengaged within 5 seconds, the operator may carry out the operation again, by pressing the button

The system’s power supply is ensured by a set of fuses located in the cabin (see figure) in the marked positions.

64 - control unit power supply

65 - automatic transmission services

66 - start prevent

There are three more 25 A fuses (electric motor power supply) that are connected with control unit pins 4, 5, and 6. In the event
that one or two of these fuses blow, the gearbox functions are not affected. If the third fuse is broken, the gearbox is not able
to operate (i.e. both the clutch motion and the gear selection/engagement will be disabled).

Accelerator pedal sensor

The accelerator pedal position is provided to the gearbox control unit, through a suitable communication line, by the EDC
electronic control unit which is informed about the position by the load transmitter fitted directly to the accelerator pedal.

Engine revs sensor

The sensor is mounted just next to the engine flywheel.

The engine running speed values are sent to the EDC electronic control unit which conveys them to the gearbox control unit
by means of a special communication line.

Vehicle speed sensor

This sensor sends the pulses to the tachometer/electronic tachograph.

The signal is duplicated by the ABS/ESP sensors available on the wheels.

DIAGNOSIS INSTRUMENTS

DISPLAY

First-level diagnosis that provides coded displaying of the errors found in the control unit memory. The information is shown
on the display only by means of diagnosis instruments.

MODUS

Computer-assisted diagnosis station used for diagnosis of braking systems, pneumatic suspensions, engines and
electronically-controlled systems.

The station is equipped with auxiliary functions, such as electronic control unit programming, spare part catalogue referencing,
time-charts, etc.

IT 2000

IT 2000 is a diagnosis instrument for all the Electronic Systems fitted to IVECO vehicles. It allows you to promptly operate on
a vehicle by recognizing the latter by means of the chassis number.

It stores the results of the diagnostic work carried out.

It can also be used as a laptop PC and is set for remote diagnosis.

Using MODUS as a mother station allows you to update and configure IT 2000.

E.A.SY.

The E.A.SY. system allows you to easily diagnose and program the various electronic control units fitted to the vehicle. It is made
up of an ECI module for communication with the electronic control units and a Panasonic PC.

The ECI module allows you, by taking advantage of the Panasonic PC, to easily carry out work on the road; in particular, diagnostic
work can be assisted by a specialized remote centre, thanks to the wireless technology incorporated into the Panasonic PC (e.g.
GPRS).
