Table 3-16. Deutz Engine Fault Codes
Description
The urea tank volume ratio is below the
threshold of <2.5%
The DEF tank level is below the threshold.
Internal actuator temperature is above
threshold.
corrupted CAN communication with actua-
tor.
Overvoltage at EGR actuator.
Undervoltage at EGR actuator.
Overcurrent to EGR actuator.
SECTION 3 - CHASSIS & TURNTABLE
Possible Cause
actual urea tank level SCRUTnk_rVol_mp [%]
is below 2.5%
actual DEF tank level SCRUTnk_rVol_mp [%]
is below the threshold
Overheating of EGR actuator during operation. Let EGR actuator cool down and check heat
CAN bus error or faulty EGR actuator.
High voltage from the battery
Low voltage from the battery.
High voltage from battery.
EGR actuator is blocked or moving very hard.
Action
Check urea level => if empty, then fill in urea
Check DEF level sensor.
If there is urea in the tank, then move the
floater of the level sensor. The floater must
be free. If you lift the sensor body, then
SCRUTnk_rVol_mp must change.
Exchange DEF level sensor, if no change of
value or it's implausible.
Check DEF level => if empty, refill
Check DEF level sensor.
If there is urea in the tank loose the sensor and
move it. The floater must be free and
move if you lift the sensor body.
SCRUTnk_rVol_mp must change. Compare
SCRUTnk_rVol_mp to:
1 = SCR_rawUTnkLvl
2 = SCR_rAdapUtnkLvl
3 = SCRUTnk_rActTnkVol
*SCRUTnk_facVolPer_mp
In case of malfunction, exchange DEF level
sen- sor.
accumulation during worst case operation.
Threshold for error detection is an internal ECU
threshold.
Check other CAN bus components. If no mes-
sage is sent, fix the wiring.
If o.k. exchange EGR actuator.
Check battery voltage.
Check battery voltage.
Check battery voltage. Check if EGR is blocked
or not running smoothly.
If everything is o.k. change EGR actuator.
