Fault codes
PID 111, Code 2.3.5 Emergency stop, coolant
level
Reason: Low coolant level
Reaction: The engine is emergency stopped and
can not be re-started until the fault is rectified.
Action:
• Check coolant level.
• Check the sensor cable for breaks and short cir-
cuits.
• Check sensor function (if installed).
Change the sensor as necessary.
NOTE! The engine is supplied without a coolant level
sensor.
SID 24, Code 2.5.1 Control rod position sensor
Reason: Actuator not connected. Faulty value from
control rod position sensor in actuator.
Reaction: Engine is emergency stopped. Actuator
can not be controlled.
Action:
• Check the actuator. Change as necessary.
• Check the cables for the actuator for breaks and
short circuits.
SID 24, Code 2.5.1 Control rod position sensor,
reference
Reason: Actuator not connected. Faulty value from
control rod position sensor in actuator.
Reaction: Engine is emergency stopped. Actuator
can not be controlled.
Action:
• Check the actuator. Change as necessary.
• Check the cables for the actuator for breaks and
short circuits.

SID 23, Code 2.5.1 Control rod position sensor,
difference
Reason: Injection pump/actuator has got stuck or is
not connected. Difference between control rod cur-
rent value and nominal value exceeds 10%.
Reaction: A fault code is generated. The fault code
disappears when the difference between control rod
current value and nominal value falls below 10%.
Action:
• Check the control rod for the injection pumps.
• Check the actuator, control rod and injection
pumps. Change as necessary.
• Check the cables for the actuator for breaks and
short circuits.
SID 23, Code 2.5.2 Injection pump, auto
calibration
Reason: Automatic actuator equalization is not pos-
sible. Faulty calibration.
Reaction: The engine is emergency stopped and
can not be re-started until the fault is rectified. The
regulator can not be activated.
Action:
• Check the actuator. Change as necessary.
• Check the actuator cables.
• Turn the ignition off and on, and check if the fault
code remains.
SID 231, Code 2.7.1 Communication fault, CAN
bus
Reason: CAN controller for CAN bus is faulty.
Reaction: --
Action:
• Check the cables.
• Check the control unit.
