978 1-2-6 29 2 Diagnostic fault check of synchronism of
hand throttle and Low idle switch(LIS). Plausibility error between sensor and idle
switch Threshold for error detection is an internal ECU
threshold.
The accelerator pedal must have detected full
load and idle plausibility at least once.
980 515 523550 12 Terminal 50 was operated for more than 2
minutes. This may happen due to short to
battery or wrong usage of Terminal 50.
Starter control is disabled until this error is
healed. Startinformation to Starter (T50-switch)
erratic/defect. Threshold for error detection is an internal ECU
threshold.
Check cabling, if sensor not working, check start
switch and if necessary replace it,
check connection cable and if necessary repair
or replace it.
992 128 105 1 Charged Air cooler down stream tempera-
ture.
Temperature below lower physical thresh-
old. Sensed temperature within intake air manifold
< threshold. actual temperature below -40°C?
exchange sensor
994 128 105 3 Charge air temperature sensor: the voltage
of sensor measured by ECU is out of the tar-
get range. Short circuit to battery.
sensor voltage > limit The sensor raw signal Air_uRawTCACDs (volt-
age) > Air_SRCTCACDs.uMin_C.
Check CAC-sensor and if necessary replace it,
check connection cable and if
necessary repair or replace it.
995 128 105 4 Charge air temperature sensor: the voltage
of sensor measured by ECU is out of the tar-
get range. Short circuit to ground or open load.
sensor voltage < limit. The sensor raw signal Air_uRawTCACDs (volt-
age) is below Air_SRCTCACDs.uMin_C.
Check CAC-sensor and if necessary replace it,
check connection cable and if
necessary repair or replace it
996 233 105 0 Charge air temperature downstream calcu-
lated by ECU is above the target range.
The ECU activates a system reaction. Charge air temperature (downstream) over
warning threshold. Check CAC system and clean it. Check fan func-
tionality.
Check cooling perfomance with temperature
measurement.
997 233 105 0 Charge air temperature downstream calcu-
lated by ECU is under the shut down thresh-
old.
The ECU activates a system reaction. Charge air temperature (downstream) over the
low threshold. Check CAC system and clean it. Check fan func-
tionality. Check cooling perfomance
with temperature measurement.
1007 682 412 3 EGR downstream temperature sensor: the
voltage of sensor measured by ECU is out of
the target range. Short circuit to battery.
sensor voltage > limit Check wiring harness to TEGR-sensor.
Exchange TEGR-sensor.
1008 682 412 4 EGR downstream temperature sensor: the
voltage of sensor measured by ECU is out of
the target range. Short circuit to ground or open load.
sensor voltage < limit Check wiring harness to TEGR-sensor.
Exchange TEGR-sensor.
1011 771 523960 0 Physical range check high for EGR cooler
downstream temperature. Sensed temperature downstream EGR-cooler
> limit. 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
