Use and maintenance
DDS tester
The main functions of the DDS tester can be summarised as follows:
- Retrieval of errors (faults) of the ignition - injection system stored in the engine control unit memory and their subsequent
deletion, if required.
- Reading of engine parameters (rpm, coolant and air temperature, atmospheric pressure, throttle opening, battery voltage,
injection times and ignition advance, etc.).
- Active diagnostics. Activation of ignition - injection system transducers to check functionality and correct control signal
(fuel pump, ignition coils, rev counter, injectors, etc.). With this function it is also possible to enter the code to override the
immobilizer.
- Road test. Makes it possible to store engine parameters recorded within a previously specified engine speed range interval.
The resulting parameters can then be analysed and displayed once they have been acquired.
- With specific sensors connected, the DDS tester can read electrical voltages, current, temperature, timing belt tension, and
pressure values (lubrication and fuel supply circuits for example).
