Engine shutdown
There is risk of the oil boiling and of damage to
the turbocharger if the engine is switched off
without cooling. The power must not be
switched off before the engine has stopped.
If the engine is fitted with a battery master switch
and an SCR system, the SCR system must run for
a while after the engine has been switched off to
allow it to cool down. During this period the
power must not be cut using the battery master
switch.
The battery voltage must remain on for a few
seconds after the 15 voltage is switched off so
that the control units can store the values and
switch to standby mode.
10 prohibited engine shutdowns in a row will
cause a torque reduction (70% of fuel quantity).
Reset the engine by switching it off correctly
once.
1. Run the engine without a load for a few min-
utes if it has been run continuously with a
heavy load.
2. Switch off the engine.
