Verify the engine control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe™ Online for applicable fixes to the calibration stored in the ECM. If necessary, calibrate the ECM.
This fault code goes active when the coolant level inside the radiator top tank or surge tank drops below the sensor level. Fill the top tank with coolant.
Note: It may not be possible to perform an aftertreatment diesel particulate filter (DPF) regeneration while this fault code is active.
Possible repairs:
1)Add coolant to the engine.
2)Replacing the coolant level sensor.
