System information

APU Will Shutdown
"REGENERATING" OR "COOLING DOWN" OR "MUST REGEN"
"HOLD ON/OFF FOR 5 SEC TO SHUT DOWN"
You attempted to shut down the APU either during a regen or when the
exhaust pressure was over 100mB. In the second case the unit will start a
regen immediately. This message indicates that the APU will shut down when
the regen cycle is completed.
Exhaust Temperature Sensor Failure
There is a problem with the exhaust temperature sensor. The system will
continue to operate normally except that the exhaust temperature is not
controlled. In this case the DPF may become overheated during regen events
and, over time, this may degrade the performance of the coatings in the
filter. Short term operation of the system is still acceptable but degraded
coatings will result in longer regeneration cycles in the future. This problem
should be fixed as soon as possible. Pressing the ESC/RESET key will clear
the message.
DPF Lost Engine Shutdown
CAN bus communication from the DPF controller to the DCP2 has been lost.
The APU will not be allowed to operate when this fault is active. Pressing the
ESC/RESET key will clear the message.
DPF Filter Plugged Engine Shutdown
If the exhaust back pressure is greater than 190mB, the filter is deemed
plugged and the APU is shut down. The engine may be restarted but if the
back pressure exceeds 190mB it will be shut down again. It may still be
possible to regen the filter and restore system function by performing an
emergency regen. Pressing a key will clear this message.
DPF Heater Fail Engine Shutdown
The exhaust temperature did not reach 500°C within 10 minutes after starting
the regen cycle. In this case the system cannot perform a regen cycle and the
APU will not operate. Pressing the ESC/RESET key will clear the message.
GEN Voltage Low Engine Shutdown
This message appears when the generator voltage to the DPF controller is
lower than 65V AC. Pressing the ESC/RESET key will clear the message.
Excessive Time Between Regens Service DPF
This message appears when there has not been a filter regeneration in
50 hours. The filter requires service and must be removed and inspected
for physical damage.

NOTICE
It is not necessary to wait for the
regen to complete before driving the
truck. Also, for safety reasons, it is
always possible to force the APU off
by holding the ON/OFF button for 5
seconds.
