1 – Troubleshooting
System faults
Active faults and cleared faults
Active faults display on the system controller’s LCD screen when they occur. The fault notification remains on the LCD
screen until the fault is cleared.
An active DTC (diagnostic trouble code) displays along with the fault codes. Engine-related faults may include numeric
fault codes called an SPN (suspect parameter number) and FMI (failure mode indicator). Make note of these codes when
they display. You may be asked to provide the codes if you contact an authorized Deutz service dealer for support. The
OC (occurrence count) appears with SPN and FMI codes. The OC identifies the number of times the failure has
occurred.
Non-active faults, or faults that have been cleared, are saved in the system’s events history. For instructions on how to
view faults that occurred in the past, see
Find system fault codes in events history on page 27.
In some cases, you may see a combination of fault notifications. For example, if the temperature sensor in the engine is
faulty, you may first see a “Check Engine” fault with SPN code 0110 and FMI code 02. The system continues to operate
until the engine reaches a predefined temperature. At that point, the system shuts off, and the “High Engine Temp” fault
message displays. See
Figure 6 .
 For more information on predefined conditions that trigger faults, see System faults triggered by predefined
thresholds on page 23.
 For more information on SPN and FMI codes, see Engine faults (SPN and FMI codes) on page 25.
