Note:
In this mode, it is possible to
set the engine speed to a defined value via the arrow keys. Furthermore,the
various Data List parameters can be displayed using the YES and NO keys.
Using the F9 key, data can be stored as in the snapshot mode.
In this test mode, TECH 1
prescribes the idle speed for the control unit. This mode can be used, if an
evaluation of the various engine parameters (e.g. O2 INTERGATOR or INJECTION
PULSE) at a fixed/increased idle speed is required or to determine whether
the idle speed adjuster is running smoothly and not jamming over the entire
dynamic range.
