Common Warning and Indicator Lamps
CHECK
CHECK Engine
Indicates a critical engine condition (low oil pressure, low
coolant level, high coolant temperature, high DPF soot level,
or uncontrolled DPF regeneration). Correct the condition as
soon as possible. If the condition worsens, the STOP engine
lamp will illuminate.
STOP
STOP Engine
Indicates a serious fault which requires engine shutdown
immediately. The engine protection system will reduce the
maximum engine torque and speed, and, if the condition
does not improve, will shut down the engine within 30 to 60
seconds.
The driver must safely bring the vehicle to a stop on the side
of the road and shut down the engine as soon as the red
light is seen. If the engine shuts down while the vehicle is in
a hazardous location, restart the engine after turning the key
to the OFF position for a few seconds. Move the vehicle to a
safer location.
High Exhaust System Temperature
(HEST)
Slow (10-second) flashing indicates a regeneration (regen) is
in progress.
Solid illumination indicates high exhaust temperatures at the
outlet of the tail pipe, when speed is below 5 mph (8 km/h).
It does not signify the need for service; it only alerts the
vehicle operator to high exhaust temperatures when a regen
is in progress.
DPF Status
Solid illumination indicates a regen is required. Change to a
more challenging duty cycle (such as highway driving ) to
raise exhaust temperatures for at least twenty minutes, or
perform a parked regen.
Blinking indicates that a parked regen is required
immediately. An engine derate and shutdown will occur.
Malfunction Indicator Lamp (MIL)
Indicates an emissions-related fault. See the engine
operation manual for details.
Vehicle ABS

When ABS is not engaged. illumination indicates a problem
with the vehicle ABS. Repair the ABS immediately to ensure
full braking capability.
Trailer ABS
Indicates the trailer ABS is engaged.
When ABS is not engaged. illumination indicates a problem
with the vehicle ABS. Repair the ABS immediately to ensure
full braking capability.
WHEEL
SPIN
Wheel Spin
Indicates the Automatic Traction Control (ATC) is engaged.
Solid illumination indicates a problem with the ATC system.
Repair the ATC system immediately to ensure full braking
capability.
High Coolant Temperature
Indicates the coolant temperature is above the maximum
allowable temperature listed in
Table 3.2
