Table 17.1 Engine Mode Selection Table
It should be noted that the engine mode switch 2 input is also used for the
following feature;
• Mode Switch 2 or Inlet Air Restriction Switch
If this alternative feature is required then associated mode switch function
cannot be used.
If an invalid switch position is selected a fault code will be raised (1743 -2) and
the feature will revert to its last good state.
IMPORTANT
If a change of governing is required i.e. from all speed to min / max then
unlike mode changes such as droop etc the engine speed must be seen
to be at low idle or 0rpm before this change will take place regardless of
the mode switch position.
17.5.2 Mode Selection Configuration
Configuration of the available engine modes is carried out by using the EST
service tool under the following menu location, Service / Engine Operating

17.5.4 Rating and Droop changes requested via the J1939 datalink
For those applications wishing to use the J1939 CAN Bus system during
machine integration, the engine rating and droop settings can be adjusted
using the Off Highway Engine Control Selection (OHECS) message PGN
FDCB. For more information on configuring the J1939 messages please refer
to section 19 of this document.
NOTE if a rating is selected over J1939 the last programmed rated speed will
be applied, as rated speed cannot be changed over J1939.
