3
After treatment SCR Inter mediate gas
temperature sensor circuit - Voltage above
normal, or shorted to high source. High signal
voltage detected at the aftreatment SCR
intermediate temperature sensor circuit.
Possible reduced engine performance.
4519
5862
4
After treatment SCR Inter mediate gas
temperature sensor circuit - Voltage below
normal, or shorted to low source. Low signal
voltage detected at the aftertreatment SCR
intermediate temperature sensor circuit.
Possible reduced engine performance.

2
After treatment SCR Inter mediate gas
temperature sensor - Data erratic, intermittent
o r i n c o r r e c t . T h e a f t e r t r e a t m e n t S C R
intermediate temperature sensor reading is
irrational.
Possible reduced engine performance.

0
A f t e r t r e a t m e n t S C R i n t e r m e d i a t e g a s
temperature - Data valid but above normal
operational range - Most severe level.
T h e a f t e r t r e a t m e n t S C R i n t e r m e d i a t e
temperature sensor reading is above the
engine protection limit.
Progressive power and/or speed derate
increasing in severity from time of alert. If the
engine protection shutdown feature is enabled,
the engine will shut down 30 seconds after the
red STOP lamps starts flashing.

16
After treatment 1 SCR intermediate gas
temperature - Data valid but above normal
operating range - Moderately severe level. High
SCR Intermediate temperature detected.
Progressive power and/or speed derate
increasing in severity from time of alert. If the
engine protection shutdown feature is enabled,
the engine will shut down 30 seconds after the
red STOP lamps starts flashing.
4526

2
Brake pedal position - Data erratic, intermittent
or incorrect. The values of the 2 brake switch
signals do not match.
None on performance.
4572

9
After treatment diesel exhaust fluid tank
temperature - Abnormal update rate.
The ECM lost communication with the
after treatment diesel exhaust fluid tank
temperature sensor.
Possible reduced engine performance.
4584

14
Aftertreatment diesel particulate filter system -
S p e c i a l i n s t r u c t i o n s . T h e i n c o r r e c t
aftertreatment diesel particulate filter system
has been installed with the engine.
Engine will be shut down.
4585
4792
14
Aftertreatment 1 SCR catalyst system - Special
instructions. The incorrect SCR system has
been Installed.
Engine will be shut down.
4612
520701
31
Engine intake manifold pressure system
monitor - Condition exists. The engine is unable
to meet the air handling system commands.
Possible reduced engine performance.
4658
4331
18
Aftertreatment SCR actual dosing reagent
quantity - Data valid but below normal operating
ra n g e - M o d e ra t e l y s eve r e l eve l . L ow
after treatment diesel exhaust fluid flow
detected.
Possible reduced engine performance.
