376 281 630 12 Internal hardware monitoring: the ECU finds
an error during the access to its EEPROM
memory or works with an alternative value Section could not be erased Threshold for error detection is an internal ECU
threshold.
There is no healing possible for the error. In the
every new initialization phase, the
debounce level is set to zero.
If not programmed, EEPROM is defect --> ECU is
defect, reprogramm ECU and if
necessary replace it.
377 281 630 12 Internal hardware monitoring: the ECU finds
an error during the access to its EEPROM
memory or works with an alternative value Minimum 3 blocks could not be readed,
EEPROM has Checksum Error There is no healing possible for the error. In the
every new initialization phase, the
debounce level is set to zero.
If not programmed, EEPROM is defect -->ECU is
defect, reprogramm ECU and if
necessary replace it
378 281 630 12 Internal hardware monitoring: the ECU finds
an error during the access to it's EEPROM
memory or works with an alternative value Block could not be written for minimum 3 times Threshold for error detection is an internal ECU
threshold.
If not programmed, EEPROM is defect --> ECU is
defect, reprogramm ECU and if
necessary replace it.
381 693 411 4 Range check cannot be done or interrupted. EGR or wiring defect Check wiring harness and connected EGR.
387 555 523612 12 Internal hardware monitoring: the CPU of
the ECU is reset and the cause is logged inter-
nally; no item will be created in error mem-
ory Injector shut off demand for the ICO coordinator
System responses:
not Threshold for error detection is an internal ECU
threshold.
Caution ! Sequence error, check error memory
for other errors.
389 214 190 0 Engine speed: the engine speed calculated
by ECU is above the target range; the ECU
activates a system reaction Overspeed monitoring during 1 level of FOC
(Failure overrun condition) if engine speed
was over Limit. check powertrain settings regarding overspeed
390 214 190 11 Engine speed: the engine speed calculated
by ECU is above the target range; the ECU
activates a system reaction Overspeed monitoring during 2 level of FOC
(Failure overrun condition) if engine speed
was over limit. check powertrain settings regarding overspeed
391 214 190 14 Engine speed: the engine speed calculated
by ECU is above the target range; the ECU
activates a system reaction Overspeed monitoring during ORC (Override
conditions) if engine speed was over
2900rpm check powertrain settings regarding overspeed
417 312 171 3 Sensor error SCR-System environment tem-
perature; DPF-System air inlet temperature;
signal range check high open loop to sensor Check cabling, if environment temperature sen-
sor is not working, check sensor
and if necessary replace it, check connection
cable and if necessary repair or replace it.
418 312 171 4 Sensor error SCR-System environment tem-
perature; DPF-System air inlet temperature;
signal range check low short circuit to Ground Check cabling, if environment temperature sen-
sor is not working, check sensor
and if necessary replace it, check connection
cable and if necessary repair or replace it
419 212 190 8 Camshaft speed sensor: the ECU receives no
signal and uses the signal from crankshaft
speed sensor as alternative to calculate the
engine speed When disturbed camshaft signal detected.
Error in sensor or wiring. Threshold for error detection is an internal ECU
threshold, occurs by disturbed
camshaft signal.
Check increment wheel position, clean and
adjust if necessary, check sensor postition.
Check Camshaft Sensor or wiring.
