The Output Diagnosis Test Mode (DTM) can
only be carried out if the engine is not running
and ignition is switched on.
The Output Diagnosis Test Mode (DTM) will be
aborted if the engine is started or a rotational
impulse is recognized.
During the Output Diagnosis Test Mode (DTM)
the individual control elements will be activated
for approx. 60 seconds or until advancing to the
next final control by pressing the button.
The Output Diagnosis Test Mode (DTM) can be
aborted by pressing the -C- button. Therefore
there is no need to continue to the end by
pressing the button. This is especially
important because the fuel injectors can be
actuated with the button according to the
firing order and fuel injector.

complete Output Diagnosis Test Mode (DTM).
