Description
Physical range check low for EGR cooler
downstream temperature.
Actuator error EGR-Valve.
Signal range check high.
Actuator error EGR-Valve.
Signal range check low.
Actuator position for EGR valve is not plausi-
ble, internal error, angular misalignement of
the flap.
Actuator error EGR-Valve; signal range check
high, measured current by ECU is over target
Actuator error EGR-Valve; signal range check
low, measured current is below target
Actuator of the external EGR valve: the ECU
detects a short circuit to battery or open
load.
Actuator of the external EGR valve: the ECU
detects a short circuit to ground.
SECTION 3 - CHASSIS & TURNTABLE
Possible Cause
sensor voltage > lower limit
Short cut to batterie.
Short cut to ground.
Position error of throttle flap (deviation > 7%). Threshold for error detection is an internal ECU
Short circuit to battery or open circuit.
Short circuit to ground.
Short cut to battery or open loop.
Short cut to ground
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
Check wiring and repair or replace if necessary,
check actuator with SERDIA test for
EGR and if necessary replace it.
Check wiring and repair or replace if necessary,

EGR and if necessary replace it.
threshold.
Threshold for error detection, deviation from
setpoint > 7%.
Troubleshooting with SERDIA 2010 Use Case
"EGR Diagnostic".
Check cabling, actuator defect, check actuator
and if necessary replace it, check
connection cable and if necessary repair or
replace it.
Check wiring, check cabels and repair or replace
if necessary, check actuator with
SERDIA 2010 test for EGR and if necessary
replace it.
Check cabling, actuator defect, check actuator
and if necessary replace it, check
connection cable and if necessary repair or
replace it.
Check cabling, actuator defect, check actuator
and if necessary replace it, check
connection cable and if necessary repair or
replace it.
