957 512 677 4 Start relay (high side power stage):
the current drain measured by ECU is above
the target range. Shortcut HighSide-output to ground. Threshold for error detection is an internal ECU
threshold.
Check cabling and start relay and if necessary
replace it,
check connection cable and if necessary repair
or replace it.
958 512 677 5 Start relay (low side power stage): the cur-
rent drop measured by ECU is above the tar-
get range Open circuit/disconnection LowSide-Output. Threshold for error detection is an internal ECU
threshold.
Check cabling and start relay and if necessary
replace it,
check connection cable and if necessary repair
or replace it.
959 512 677 12 Start relay (low side power stage): the cur-
rent drop measured by ECU is above the tar-
get range. Temperature over limit. Threshold for error detection is an internal ECU
threshold.
Check cabling and start relay and if necessary
replace it,
check connection cable and if necessary repair
or replace it.
960 512 677 3 Start relay (low side power stage): the cur-
rent drain measured by ECU is above the tar-
get range. Shortcut LowSide-Output to battery. Threshold for error detection is an internal ECU
threshold.
Check cabling and start relay and if necessary
replace it,
check connection cable and if necessary repair
or replace it.
961 512 677 4 Start relay (low side power stage): the cur-
rent drop measured by ECU is above the tar-
get range. Shortcut LowSide-Output to ground. Threshold for error detection is an internal ECU
threshold.
Check cabling and start relay and if necessary
replace it,
check connection cable of terminal 50 and if
necessary repair or replace it.
973 555 523612 14 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. Visibility of Softwareresets in DSM Threshold for error detection is an internal ECU
threshold.
974 555 523612 14 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. Visibility of Softwareresets in DSM Threshold for error detection is an internal ECU
threshold.
975 555 523612 14 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 Visibility of SoftwareResets in DSM Threshold for error detection is an internal ECU
threshold.
If possible the software update has to be done.
Replace the ECU.
976 2-2-6 91 11 Diagnostic fault check of synchronism of sin-
gle potentiometer and Low idle switch(LIS). Measured voltage of accelerator pedal 1 is out of
plausible range. Threshold for error detection is an internal ECU
threshold.
Check cabling, check accelerator pedal and
pedal sensor and if necessary replace it,
check connection cable and if necessary repair
or replace it.
When the PWM period APP_tiPWMPer is in
between APP_tiSRCLoPWMPer_C and
APP_tiSRCHiPWMPer_C .
