7.3 Diagnostic possibilities with the SERDIA software
SERDIA (Service Diagnosis) is a software program with the aid of which the user can monitor the measure-
ment value on a running diesel engine from a PC or Notebook computer and can thus recognize faulty ope-
rating behaviour.
!
With a stopped engine, it is possible to enter certain parameters in a targeted manner from the PC into
the control unit (parameter setting) in order to change the operating behaviour of the engine.
!
With the aid of the SERDIA diagnostic software, the fault messages stored in the control unit can be
read out and evaluated.
Information is displayed on the following:
- Fault locality (e.g. pedal sensor, coolant temperature sensor).
- Fault type (e.g. lower limit exceeded, sporadic error).
- Environmental data/operating data (speed and operating hours at the time of the occurrence of the last
fault).
- Number of fault localities
- Frequency of the fault
- Fault status (
active - fault persists / passive - fault eliminated).
Fault messages of non-current and eliminated faults can be deleted with SERDIA.

Function test
In the function test, the outputs and the control rod travel can be activated with the engine stopped.

Input/output assignment

Measuring value depiction
A large selection of measuring values are available and these can also be used if there is no EMR 2 error
(starting behaviour, engine saws, poor performance).
For this purpose, the PC is connected by an interface cable to the diagnostic interface. Communication
with the control unit is carried out via a special EMR 2 protocol.
Working with SERDIA is described in a separate operating instruction.
