Description
Urea supply module pump: the ECU can not
measure any reaction during pump control
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

The exhaust temperature value from the
sensor before DOC
is above an applicable upper shutoff
thresh-

Action
Threshold for error detection is an internal ECU
threshold
The hardware detects the presence of load on
the PWM output power stage for the
urea pump module actuator. Check wiring

Check Turbocharger and Piping each for
leakage
and correct function
Check injectors: is an injector got stuck?
