ENGINE DIAGNOSTICS
General
The Cummins QSX15 Engine has two types of fault codes:
• Engine electronic fuel system fault codes
• Engine protection system fault codes
All fault codes are either active or inactive. Active engine
faults can be viewed on the crane’s digital display either with
the engine running or with the engine off (run/stop/run switch
in RUN position). Inactive faults can only be read with
electronic service tool supplied by the engine manufacturer.
The engine diagnostic lights are mounted on the front
console in the operator’s cab as shown in Figure 7-3
.
RED STOP LIGHT
When on, the red stop light indicates the need to stop
engine as soon as safely possible and correct the fault.
YELLOW WARNING LIGHT
When on, the yellow warning light indicates that engine can
be run, but the fault should be corrected as soon as possible.
WHITE MAINTAIN LIGHT
When on, the white maintain light indicates that engine
maintenance is required. See engine manufacturer’s manual
for maintenance instructions.
On-Board Engine Diagnostics
Engine Diagnostics — Cummins
Active engine faults can be viewed on the crane’s digital
display either with the engine running or with the engine off
(run/stop/run switch in RUN position). A laminated list of fault
codes is located in the operator’s cab.
• Scroll up or down with rocker on right side of digital
display until Engine Diagnostics screen appears.
• Corresponding flash code for each active fault will
appear next to FLASH CODE as shown in Figure 7-4
.
The screen will automatically scroll through each fault at
two-second intervals if more than one fault exists.
DPF Diagnostics — Tier 4
See Figure 7-5 for the following procedure.
DPF High Temperature
GLOWS YELLOW to alert crane operator that the exhaust
system temperature is higher than normal due to DPF
regeneration.
DPF Condition
Displays one of three conditions if the Regeneration Inhibit
switch is on (reference the Engine Manufacturer’s Manual for
additional information):
• GLOWS YELLOW when DPF is active and starting to fill.
Turn off regeneration inhibit switch. No immediate
action is required.
• FLASHING when DPF is nearly full. The operator may
sense a reduction in power. Turn off regeneration
inhibit switch. Perform a manual stationary
regeneration of the DPF at earliest convenience.
CAUTION
If possible, lower lifted loads to ground and then stop
engine as soon as possible when red stop light comes on.
Permanent damage can occur if engine is run while red
stop light is on. Do not run engine until fault is corrected.

WARNING
High Exhaust Temperatures!
Active DPF Regeneration can occur at low engine idle as
well as during crane operation. This may result in high
exhaust temperature. Always keep personnel well away
from the exhaust to prevent injury and possible death.
