FEBRUARY 2003 EDITION
“Common sense” tests, such as exposing heat-sensitive parts
to heat (plastic, wiring, electronic units, etc.….), and those
that for years have characterized the quality of the work per-
formed in yards, are not mentioned herein, although they are
of the utmost importance.
Tests to verify the engine’s and the electronic control system
components’ operating condition can be performed quickly
and with top reliability using specific diagnostic tools, available
to the IVECO Aifo Technical Assistance Centers.
Lubricating oil fill
Lubricating oil transfer operations are simplified by the pres-
ence of an electrical control system. Manual controls for
transfer and pre-lubrication operations are positioned on the
unit above the EMB. For safety reasons, controls are enabled
only with the key switch in the “OFF” position
Sequence
1. Place the stable switch in the “ON” position, thus ener-
gizing the switching solenoid valve to place the empty-
ing/filling junction in communication with the electrical
pump and with the oil sump.
2. Use the intake/exhaust push-button to complete the
desired operation.
3. Place the stable switch back to the “OFF” position.
Fuel tank suction
Check assembly suction at the maximum allowed longitudi-
nal and transverse inclinations, with such a residual quantity
in the tank as to cause the reserve indicator light to stay on
permanently.
Verify the absence of air in the fuel feed pipeline, using a clear
pipe placed, in inverted “U” fashion, before the engine inlet.
Throttle position sensor
Verify, in the idling and maximum rpm positions, the correla-
tion between the throttle on the bridge and the sensor rod,
noting:
❏
Whether, with the lever in the idle position, the switch in
the sensor is electrically open.
❏
Whether in the maximum rpm position the sensor rod
reaches the mechanical end stop.
Pre-lubrication
The task of pre-lubricating the engine’s internal components
is managed and controlled by an electronic circuit of the
EMB; the operation can also be conducted by acting manu-
ally, with the key switch in the “OFF” position, only on the oil
intake/exhaust push-button positioned on the related unit. If
the push-button is placed for a few seconds in the
“EXHAUST” position, the filters and the internal engine
ducts will be filled.
