Table 3-16. Deutz Engine Fault Codes
Description
CAN message is not received fora definite
time => error is set. As soon as the
message is received the error heals.
CAN message is not received for a definite
time => error is set. As soon as the
message is received the error heals.
Timeout error of CAN-Receive-Frame
ComRxEBC2 from wheel speed sensor.
The error shows up, if no proper urea
pressure could be build up within the SCR
system
state "Fill Lines" => SCRCo_stStatus_mp
=
1.
SECTION 3 - CHASSIS & TURNTABLE
Possible Cause
CAN message is not received for a definite
time
=> error is set. As soon as the message is
received the error heals.
CAN message is not received for a definite
time
=> error is set. As soon as the message is
received the error heals.
Timeout Error (Missing CAN Bus message)
Defect on wheel speed sensor.
This error shows up, if no proper urea presure
could be build up within the SCR system
state "Fill Lines" => SCRCo_stStatus_mp =
1.
3 cases can lead to the error:
Case A: increasing pressure is detected within
15s the check has passed => no error
Case B: The pressure threshold was not
reached within the 60s but case A was not
positiv.
Case C: The minimum pressure of 3000 hPa
was not reached within the 60s.
Action
Check eletrical connection oif urea quality sen-
sor
Check engine CAN bus
Check urea quality sensor itself
Exchange urea quality sensor
Check eletrical connection of suction unit sen-
sor (combined sensor with tank level and
tank temperature) Check engine CAN bus
Check level sensor itself Exchange suction unit
Check CAN Bus cabling (Bus scheduling,
polarity, short circuit, power interrupt), test
protocol of receiver, check CAN functional
range.
Replace the wheel speed sensor.
Make sure that DEF lines, pump and tank are
not frozen.
Check for DEF level in the tank. Check DEF
lines:
Are all DEF lines connected?
Is the suction line blocked?
Is ther any leakage? Not only urea to the
outside but also air into the lines, especially in
the suction line!
Perform SERDIA usecase "pressure test":
Does the DEF pump work? => check wiring
har- ness & PWM signal for pump.
Does the urea pressure increase? All errors are
already healed?
If still unsuccessful so far:
Check urea pressure sensor: At ignition on and
SCR system state = 0 ("Init check"),
SCR_pAbsAdapUPmpP shall be identical to
EnvP_p. Fulfilled: Sensor okay!
Check DEF pump filter: Is any dirt inside?
Suspected components: Suction line
PWM Powerstage has a defect and a default
value which leads not to a rising pressure
DEF pump pressure sensor defect
DEF pump filter contains dirty parts
