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 (carry out corresponding TECH 1
adjustment section 2.1.5.1).
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. O2 INTEGRATOR or INJECTION PULSE) at increased or
decreased idle speeds.
