1012 771 523960 1 Physical range check low for EGR cooler
downstream temperature. sensor voltage > lower limit 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
1014 594 5763 6 Actuator error EGR-Valve.
Signal range check high. Short cut to batterie. Check wiring and repair or replace if necessary,
check actuator with SERDIA test for
EGR and if necessary replace it.
1015 594 520521 5 Actuator error EGR-Valve.
Signal range check low. Short cut to ground. Check wiring and repair or replace if necessary,
check actuator with SERDIA test for
EGR and if necessary replace it.
1016 594 5763 7 Actuator position for EGR valve is not plausi-
ble, internal error, angular misalignement of
the flap. Position error of throttle flap (deviation > 7%). Threshold for error detection is an internal ECU
threshold.
Threshold for error detection, deviation from
setpoint > 7%.
Troubleshooting with SERDIA 2010 Use Case
"EGR Diagnostic".
1022 5-9-4 5763 6 Actuator error EGR-Valve; signal range check
high, measured current by ECU is over target Short circuit to battery or open circuit. Check cabling, actuator defect, check actuator
and if necessary replace it, check
connection cable and if necessary repair or
replace it.
1023 5-9-4 5763 5 Actuator error EGR-Valve; signal range check
low, measured current is below target Short circuit to ground. Check wiring, check cabels and repair or replace
if necessary, check actuator with
SERDIA 2010 test for EGR and if necessary
replace it.
1024 594 5763 3 Actuator of the external EGR valve: the ECU
detects a short circuit to battery or open
load. Short cut to battery or open loop. Check cabling, actuator defect, check actuator
and if necessary replace it, check
connection cable and if necessary repair or
replace it.
1025 594 5763 4 Actuator of the external EGR valve: the ECU
detects a short circuit to ground. Short cut to ground Check cabling, actuator defect, check actuator
and if necessary replace it, check
connection cable and if necessary repair or
replace it.
