585 163 656 3 Injector cyl. 6: the current drop measured by
ECU is above the target range Suspected Components:
injector cylinder 6
wiring harness, cable break or short circuit, sen-
sor defective, connection cable Threshold for error detection is an internal ECU
threshold.
Check wiring harness, injectors and if necessary
repair/replace it. Use SerDia Injector
test for diagnosis.
592 135 523615 5 Detecting an open load fault in the metering
unit wiring harness defective, cable break Threshold for error detection is an internal ECU
threshold.
Check wiring harness and metering unit if nec-
essary repair/replace it.
593 135 523615 12 powerstage of metering unit is overheated over temperature Threshold for error detection is an internal ECU
threshold.
Check functionality of metering unit and
replace it if needed.
Check temperature of metering unit and
improve the installation in case of overheating.
594 135 523615 3 Fuel metering unit: the current drain mea-
sured by ECU is above the target range short circuit to battery high side Threshold for error detection is an internal ECU
threshold.
Check wiring harness and metering unit if nec-
essary repair/replace it.
595 135 523615 4 Fuel metering unit: the current drain mea-
sured by ECU is above the target range short circuit to ground high side Threshold for error detection is an internal ECU
threshold.
Check wiring harness and metering unit if nec-
essary repair/replace it.
596 135 523615 3 Fuel metering unit: the current drain mea-
sured by ECU is above the target range short circuit to battery low side Threshold for error detection is an internal ECU
threshold.
Check wiring harness and metering unit if nec-
essary repair/replace it.
597 135 523615 4 Fuel metering unit: the current drain mea-
sured by ECU is above the target range short circuit to ground low side Threshold for error detection is an internal ECU
threshold.
Check wiring harness and metering unit if nec-
essary repair/replace it.
612 555 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. Plausibility check failed (MoCADC_uNTP_mp is
higher than MoCADC_uNTPMax_C). Threshold for error detection is an internal ECU
threshold.
If error is still present, exchange ECU.
613 555 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 Analysis of test voltage (Value is out of the tar-
get -> ECU internal error) Threshold for error detection is an internal ECU
threshold.
Check wiring, check connected sensors actua-
tors.
If error is still present, exchange ECU.
614 555 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 memory Analysis of the ratiometric correction (Value is
out of the target -> ECU internal error) Threshold for error detection is an internal ECU
threshold.
Check wiring, check connected sensors actua-
tors.
If error is still present, exchange ECU.
615 555 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 memory Error report due to an error in the plausbility of
Function Coordination(FC) and
Monitoring Modul(MM)(ECU internal error) Threshold for error detection is an internal ECU
threshold.
If error is still present, exchange ECU.
