Table 3-10. Engine Fault Codes
Description
@ engines < 4l:
Throttle valve error, Open Load or Short cut
to Battery, blocked valve or wrong control
signal for valve.
@ engines with Burner T4i:
Pressure Sensor error after valve (DV2),
lower limit reached
CAN bus 0: the ECU is not allowed to send
messages, because the status "BusOff" is
detected.
CAN bus 1: the ECU is not allowed to send
messages, because the status "BusOff" is
detected
Warning, no diagnostic with SERDIA2010
possible
CAN bus 2: the ECU is not allowed to send
messages, because the status "BusOff" is
detected.
Warning, depends on engine, EAT.
Charge air pressure messured by sensor is
above the shut off threshold.
Charge air pressure messured by sensor is
above the warning threshold
Coolant temperature sensor: the voltage of
the sensor measured by ECU is out of the tar-
get range.
Coolant temperature sensor: the voltage of
the sensor measured by ECU is out of the tar-
get range
Coolant temperature sensor: the voltage of
the sensor measured by ECU is out of the tar-
get range
Coolant temperature: the coolant tempera-
ture calculated by ECU is above the target
range; the ECU activates a system reaction
Possible Cause
The sensed raw voltage value is below the mini-
mum threshold.
CAN BusOff error; CAN 0 (Customer CAN)
CAN BusOff error; CAN 1 (Diagnostic CAN)
CAN BusOff error; CAN 2 (Engine CAN)
Charged air cooler pressure below threshold.
Charge air pressure above shut off threshold
Suspected components:wiring harness, cool-
ant temperature sensor.
Short cut to battery or open load.
Voltage Surveillance has found shortcut to
Ground at Coolant Temperatur Sensor.
Cooling temperature too high. Coolant temper-
ature above warning threshold
Action
The sensed raw voltage value
DPM_uRawBrnDVDsP is above the minimum
threshold
DPM_SRCBrnDVDsP.uMin_C
@ CRT < 4l: check throttle valve
@ engines with Burner T4i: check back-pressure
valve
Threshold for error detection is an internal ECU
threshold.
BusOff bit for CAN A node is set.
Check wiring of CAN bus and if necessary repair
it, check connection cable and if
necessary repair or replace it, check resistance in
CAN lines (120 Ohm)
Threshold for error detection is an internal ECU
threshold.
BusOff bit for CAN B node is set.
Check wiring of CAN bus and if necessary repair
it, check connection cable and if
necessary repair or replace it, check resistance in
CAN lines (120 Ohm)
Threshold for error detection is an internal ECU
threshold.
BusOff bit for CAN C node is set.
Check wiring of CAN bus and if necessary repair
it, check connection cable and if
necessary repair or replace it, check resistance in
CAN lines (120 Ohm)
Check waste gate system if necessary replace
TC,
check CAC if all channels are clean,check charge
air piping if nececery.
Check waste gate system if necessary replace
TC, check CAC if all channels are clean,
check charge air piping if necessery.
Check wiring harness and connected Coolant
Temp Sens.
Check sensor and if necessary replace it, check
connection cable and if necessary
repair or replace it.
Check sensor and if necessary replace it, check
connection cable and if necessary
repair or replace it
Measure Voltage at Coolant Temperature Sen-
sor and renew harness if needed.
Clean radiator, check fan drive, check coolant
level, check cooling system in general,
check thermostat function, check water pump
