Description
Urea supply module pump: the current drain
measured by ECU is above the target range
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
Urea supply module pressure sensor: the
current drain measured by ECU is above the
target range
Urea supply module pressure sensor: the
current drain measured by ECU is above the
target range
The sensed raw voltage value
SCR_uRawUPmpP is above
SCR_SRCUPmpP.uMin_C
Urea supply module reversal valve: the cur-
rent drain measured by ECU is above the tar-
get range
Urea supply module reversal valve: the cur-
rent drain measured by ECU is above the tar-
get range
Urea supply module reversal valve: the cur-
rent drain measured by ECU is above the tar-
get range
Possible Cause
Shortcut to ground
If this error detected during the heating phase is
a result error: KWP 1089
Broken wiring
Pump in urea supply module defect
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)
Shortcut to battery

Action
Threshold for error detection is an internal ECU
threshold
The hardware detects a short circuit to ground
error on the PWM output power stage
for the UreaPump Module Motor Actuator. The
error is updated by setting bit 1 of
measuring point UPmp-
