Hello, my name is***** is a common problem caused by a failed Reductant Heater And Sensor. Access and unplug the glow plug control module. Then perform the following reductant heater resistance test as shown in link. If the resistance is wrong at the GPCM, then access the reductant heater and test the resistance. If the resistance is wrong at the heater, replace the heater. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
