Diagnosis
The engine control unit features a system
diagnosis function. Malfunctions that occur
during operation are stored in the fault code
memory and can then be read out with the
Volkswagen diagnosis system tester V.A.G 1552.
Diagnosis with the fault readout unit V.A.G 1551
and the diagnosis system tester VAS 5051 is also
possible.
It will also be possible to read out the data with
the diagnosis system VAS 5052 that will be
introduced at a later point in time.
The diagnosis interface is located behind the
cover with the lettering "Marine" on the control
panel. Another diagnosis connector is located in
the central electrics unit.
After connecting the diagnosis system tester to
the diagnosis interface, "fast data transmission"
ensures the system diagnosis function is used
optimally.
The diagnostic connection to the engine control
unit is established by entering the "address
word 01".
The system diagnosis contains the following
functions:
• Function 01 – Check control unit version
• Function 02 – Check fault code memory
• Function 03 – Actuator diagnosis
• Function 04 – Basic setting
• Function 05 – Delete fault code memory
• Function 06 – End output
• Function 07 – Not used
• Function 08 – Read measured value block
