Table 3-16. Deutz Engine Fault Codes
Description
Standstill escalation by time. In case the
standstill request will not be released
within
50 h by the driver this fault code will be set.
The absolute pressure value of the urea
pump is greater than an applicable
maximal filtered pressure threshold
Urea supply module pressure sensor: The
absolute pressure value of the urea pump is
less than an applicable minimal filtered
pressure threshold
absolute difference of sensed urea pump
pressure (SCR_pAbsSensUPmpP) and
ambi- ent pressure (EnvP_p) > limit
abs(UPmpP_pDiffPmpEnv_mp) >
UPmpP_pDiffPmpEnv_C (250 hPa)
Urea heater supply line: the current drain
measured by ECU is above the target range
Urea heater supply line: the current drain
measured by ECU is above the target range
Urea heater supply line: the current drain
measured by ECU is above the target range
Urea pressure line heater: the current drain
measured by ECU is above the target range
SECTION 3 - CHASSIS & TURNTABLE
Possible Cause
Stand-still request ignored by the operator.
Display / stand-still request lamp broken.
Suspected Components: Urea pump defect
Supply module pressure sensor defect
Pump contains dirty parts
Check the urea pump
Check the supply module pressur sensor
Clean the urea pump (filter)
absolute difference of sensed urea pump pres-
sure (SCR_pAbsSensUPmpP) and
ambient pressure (EnvP_p) > limit
abs(UPmpP_pDiffPmpEnv_mp) >
UPmpP_pDiffPmpEnv_C

If this error detected during the heating phase
is a result error: KWP 1089
broken heating element in pressure line
Action
Perform Stand-still. If soot load level of DPF
has increased too high already call service
to perform stand-still.
In case the DPF soot load level remove DPF
=> Exchange DPF.
Check the urea pump
Check the supply module pressure sensor
Clean the urea pump (filter)
Check the urea pump
Check the supply module pressur sensor
Clean the urea pump (filter)
Check environment pressure sensor (EnvP_p)
=> plausible value?
Engine shut-off and immediately re-started?
=> Shut-off again. Wait until afterun of
ECU has finished, re-Start engine
Back-flow line free? Does the urea pump pres-
sure show values < 1000 hPa in SCR
state emptying (64)?
Check revision valve => Does the urea pump
pressure show values < 1000 hPa in SCR
state emptying (64)? => exchange supply
module
Supply module pressure sensor defect =>
exchange supply module
