1239 788 523984 3 Actuator relay 5: the voltage measured by
ECU is out of the target range Short-Circuit to battery to component Threshold for error detection is an internal ECU
threshold.
Check wiring, component, ECU
1241 176 523986 4 Actuator relay 4: the voltage measured by
ECU is out of the target range Short-Circuit to ground to component Threshold for error detection is an internal ECU
threshold.
Check wiring, component, ECU
1242 791 523987 4 Actuator relay 5: the voltage measured by
ECU is out of the target range Short-Circuit to ground to component Threshold for error detection is an internal ECU
threshold.
Check wiring, component, ECU
1337 565 2797 4 Injector diagnosis: Timeout of Injetor detec-
tion cylinder bank 0 Short-Circuit to ground on component wiring Threshold for error detection is an internal ECU
threshold.
Check wiring, component, ECU
Note: affected injector has to be evaluated
according to firing order
1338 566 2798 4 Injector diagnosis: Timeout of Injetor detec-
tion cylinder bank 1 Short-Circuit to ground on component wiring Threshold for error detection is an internal ECU
threshold.
Check wiring, component, ECU
Note: affected injector has to be evaluated
according to firing order
1339 565 2797 4 Injector test: Short cut to ground on cylinder
bank 0 Short-Circuit to ground on component wiring Check wiring, component, ECU
Note: affected injector has to be evaluated
according to firing order
1340 566 2798 4 Injector test: Short cut to ground on cylinder
bank 1 Short-Circuit to ground on component wiring Check wiring, component, ECU
Note: affected injector has to be evaluated
according to firing order
1381 839 164 2 Rail pressure safety function is not executed
correctly Rail pressure is still above threshold. Threshold for error detection is an internal ECU
threshold.
Reset the fault and at reappearance check ECU
and injection system
1398 681 1136 0 ECU internal temperature; temperature
measured by ECU is out of the target range Short-Circuit in ECU, ECU heated by hot air Close warm air circuits, replace ECU
1425 226 172 0 sensed intake air temperature at air filter >
physical high limit sensed intake air temperature at air filter >
physical high limit Check outside conditions:
Temperature > Threshold within the intake air
system of the engine?
E.G: engine sucks in air from hot asphalt out of
paver bucket
Sensor positioned within black air filter housing
above engine lid at hot environmental
conditions and idling or similar?
=> if yes check with application team to adapt
limits
if not check sensor and wiring harness
exchange sensor
