WARNING Indication light

The ECU carries out a control activity on the operating

conditions through the analysis of the detected operating

parameters; it evaluates the behaviour of the single signals

emitted by the sensors and classifies the situation, according

to predetermined threshold, activating the red indication

light (9 figure 45).

Blinking indication light - warning level:

Lighting cycle of 0.6 s and pause of 0.24 s.

It indicates that the value is slightly above the normal

threshold; the user of the vessel does not notice any

difference in the engine behaviour.

Indication light constantly On - derating level:

It indicates that the value is significantly above the normal

threshold; the maximum power of the engine is reduced to

protect its intactness. The user of the vessel can notice the

reduction of the power of the engine.

NOTES

Only the current anomalies enable the behaviour specified

above; a temporary anomaly causes the lighting of the

indication light, according to the modalities illustrated, for

the whole period the anomaly is present. The emission code

stops when the operating conditions are restored, while

the data concerning the anomaly are stored in the failure

memory of the ECU.

The signalling is available on the relay box only, and does not

involve any other indications on the instrument panel.

The stored information are able to be decoded and erasable

by the IVECO SERVICE TOOL.

SHUTDOWN (preliminary)

When the most critical thresholds exceed their normal

values, it can be enabled the forced engine shutdown.

The next time the engine is started, if the normal operation

are restored, there will not be any lighting signalling, while

the data concerning the anomaly are stored in the failure

memory of the ECU.

Parameter list that can cause warning, derating or shutdown

conditions:

Engine coolant high temperature

Intake air high temperature

Engine oil low pressure

Engine overspeed

Fuel high temperature

Engine oil low temperature

Engine oil high temperature

Rail low pressure

Rail high pressure

Loss on the high pressure fuel line

Intake air high pressure

Intake air low pressure

Power supply voltage

Signalling maintenance interval expiration

The lighting of the indication lights MAINTENANCE (8

figure 45), caused by the ECU, indicates the need to perform

the periodical lubricating oil replacement.

When the operation is performed, it is necessary to press

the button (4 figure 45) to restore the counter and begin a

new operating cycle. The signalling is available on the relay

box only, and does not involve any other signalling on the

instrument panel.
