Press key F8 in the system main menu, select the
desired test using the arrow keys and confirm with Yes.
Follow the instructions in the TECH 1 display
Note:
In this mode, it is possible to increase / decrease the
engine idle speed in the range from 640 to 1440 rpm using the arrow
keys. The newly set engine speed is however not permanently stored in the
control unit (see table 6, System Modification F6:
ADJUSTMENTS, no. 01)
In addition, the YES and NO keys can be used to display the
various data list parameters.
The F9 key is used to store data as in the snapshot mode.
In this check mode, TECH 1 specifies the previously
adjusted engine speed to the control unit and the control unit regulates the
engine to this speed.
This mode should be used if it appears necessary to evaluate
the various engine parameters (e. g. 02 INTEGRATOR
or INJECTION PULSE) at increased or
decreased idle speeds.
