Description
DLC Error of CAN-Receive-Frame AT1O1Vol
NOX Sensor (SCR-system downstream cat;
DPF-system downstream cat); length of
frame incorrect.
Timeout Error of CAN-Receive-Frame
AT1OG1Vol; NOX sensor (SCR-system
down- stream cat; DPF-system
downstream cat).
Urea dosing valve (low side power stage):
the current drain measured by ECU is above
the target range
Urea dosing valve (high side power stage):
the current drain measured by ECU is above
the target range
Urea dosing valve (low side power stage):
the current drain measured by ECU is above
the target range
Urea dosing valve (high side power stage):
the current drain measured by ECU is above
the target range
Urea dosing valve: the current measured
value by ECU at the end of the injection is
too high
The integrated diagnostic of the tempera-
ture sensor of the Urea Quality Sensor
recog- nized a short circuit to battery.
The UQS Sensor is an combined sensor of
tank temperature, filling grade and DEF
quality and it is also an CAN sensor --> no
PIN
The integrated diagnostic of the tempera-
ture sensor of the Urea Quality Sensor
recog- nized a short circuit to ground
Possible Cause
Failure of the CAN Bus message

Check the CAN bus communication of the suc-
tion unit. In case the communication is
corrupt, exchange the suction unit.
Check the wiring to the suction unit of the DEF
tank.
Check the CAN bus communication from the
suction unit. In case the signal is corrupt,
exchange the suction unit in the DEF tank.
