Description
Physical range check high for EGR cooler
downstream temperature.
Physical range check low for EGR cooler
downstream temperature.
Power stage diagnosis disabled; Indicating
that battery voltage is not high.
Power stage diagnosis disabled; Indicating
that battery voltage is not low.
Actuator relay 5: the voltage measured by
ECU is out of the target range
Actuator relay 4: the voltage measured by
ECU is out of the target range
Actuator relay 5: the voltage measured by
ECU is out of the target range
CAN; not used
CAN; not used
Low fuel pressure: the low fuel pressure
calculated by ECU is underneath the target
range; the ECU activates a system reaction
Possible Cause
Sensed temperature downstream EGR-cooler
> limit.
sensor voltage > lower limit
Power stage diagnostic can be deactivated
due to too high battery voltage.
Power stage diagnostic can be deactivated
due to too low battery voltage.
Short-Circuit to battery to component
Short-Circuit to ground to component
Short-Circuit to ground to component
not used
not used
Fuel pressure below warning threshold
Action
EGR-Valve blocked open
EGR-Valve actuator defect
EGR-cooler defect (check for coolant water)
Reed Valve defect
Intake throttle blocked in closed position
Exhaust pressure too high
Check Nox-sensor upstream SCR catalyst dp
venturi sensor defect
EGR-Valve blocked open
EGR-Valve actuator defect
EGR-cooler defect (check for coolant water)
Reed Valve defect
Intake throttle blocked in closed position
Exhaust pressure too high
Check Nox-sensor upstream SCR catalyst dp

Check wiring, check alternator, check cables
and repair or replace if necessary.
Check wiring, check alternator, check cables
and repair or replace if necessary.
Threshold for error detection is an internal ECU
threshold.

Check low fuel pressure system (fuel feed
pump, relay , fuse, wiring, sensor) and if
necessary repair or replace it.
