Information about the engine electronics
This engine is equipped with an electronic DEUTZ
control unit.
The equipping of the respective system depends on
the desired scope of function and the planned type of
engine application.
The resultant wiring with pin assignment can be seen
in the appropriate wiring diagram.
The installation regulations of the DEUTZ AG must
also be taken into account.
Precautions
The connections of the control units are
only dust and water proof when the mating
plugs are plugged (protection class IP69K)!
The control units must be protected against
spray water and moisture until plugging in
the mating plugs!
Reverse polarity can lead to failure of the
control unit.
To avoid damaging the control units, all the
connections on the control unit must be dis-
connected before electric welding work.
Interventions in the electrical system con-
trary to the DEUTZ regulations or by un-
qualified personnel can permamently
damage the engine electronics and have
serious consequences which are not cov-
ered by the manufacturer's guarantee.
Installation instructions
The control units are calibrated to the respective en-
gine and identified by the engine number. Every en-
gine may only be operated with the appropriate
control unit.
Setpoint transmitters (pedal value transmitters) nec-
essary for vehicle operation must be connected to
the vehicle side cable harness and calibrated with
the DEUTZ diagnostic program SERDIA (SERvice
DIAgnosis). Wiring and cable assignment of the ve-
hicle side cable harness must be taken from the con-
nection diagram of the DEUTZ installation
consulting.
It is strictly prohibited:
a) to make changes or connections to the
wiring of the electrical control devices and
the data transmission cable (CAN lines).
b) to switch control units.
Diagnostic and maintenance work may
only be carried out by authorised personnel
using equipment approved by DEUTZ.
Supply voltage
DEUTZ diesel engines must be operated with a 12 V
or 24 V supply. An adequate charging condition of
the battery must be ensured. Interruption of the pow-
er supply when the engine is running can lead to
damage to the electrics/electronics. Failure of the
supply voltage leads to engine standstill.
Voltages above 32 Volt will destroy the control unit.
Diagnostics
DEUTZ control units are equipped with self-diagno-
sis. Active and passive error entries are saved in the
error memory. Active errors are displayed by error
lamp/diagnostic lamp (
65
). The active errors can
be called by blink codes or by the DEUTZ diagnostic
program SERDIA. Passive errors must be deleted by
SERDIA.
