The "dds" diagnostic system lets you diagnose any faults in the injection-ignition system via a serial port. The system is also equipped with functions to test various devices on the motorcycle. The dds diagnosis instrument can be used to measure current and voltage on any electrical device, to perform tests on individual components and to measure pressure and temperature values.
The dds (1) part number 97900.0215 Consists of a palmtop display (a), a bbad self-diagnosis module (b) and a display memory card (c).



The touch-screen display unit (a) serves for both data display and input, using the stylus housed on the side of the unit.
The self-diagnosis module (b) enables communication between the dds diagnosis instrument (1) and the motorcycle’s on-board electronic control unit (ecu).
The user interface software resides in the display memory card (c) which is housed in the palmtop display unit (a).
The display unit is equipped with two connection panels: one at the top of the instrument and one at the bottom.
The top connection panel has 6 connection sockets with the following functions:

The bottom connection panel has 3 connection sockets with the following functions:

You can connect a printer to the dds diagnosis instrument (1) to print test reports: connect the printer to the serial port (com1) (g) located on the top connection panel of the tester (1).
