D. Disconnect the connector for the suspect injector from the
cylinder head.
E. Use a multimeter to check the resistance between the ter-
minals for the suspect injector on P2 and all other terminals on
P2. Refer to Illustration 118 .

Mode Selection - Test
This procedure covers the following diagnostic code:
This procedure is only applicable to applications
equipped with a mode selection switch.

The Electronic Control Module (ECM) detects a combination of switch posi-
tions for the mode switches that has not been defined.
If equipped, the warning lamp will come on and the ECM will log the diagnostic
code.
The ECM will return the engine to the last good mode selection or setting.
The engine will start and the engine will default to the previous mode selection.
The engine may operate at reduced speed or reduced power depending on
the mode that is selected.
Follow the troubleshooting procedure in order to identify the root cause of the fault.
Use this procedure to check if the mode selection
switch operates correctly.
The mode selection switch inputs provide the
operator with the ability to select a maximum of four
different modes of operation. Different modes of
operation can be used giving the operator a means to
select the most efficient method of completing the
required work.
Each mode has a single fuel limit map, a rated
speed, and a matched fuel delivery. Each mode also
has a specific droop value for throttle 1 and throttle 2.
Table 193
Mode
Number
Switch 2 Switch 1 Enabled
1 Open Open Y/N
2 Open Closed Y/N
3 Closed Open Y/N
4 Closed Closed Y/N
If a fault occurs in the circuit for either of the switches,
the mode of operation will be different to the mode
that was selected. If the mode of operation is not
enabled on the application, a 2882-2 diagnostic code
will become active.
