侍# Some fault codes are not applied to this machine. 3-31 Fault code J1939 SPN J1939 FMI Reason Effect (only when fault code is active) 1677 3031 4 Aftertreatment diesel exhaust fluid tank temperature sensor - Voltage below normal or shorted to low source. Low signal voltage detected at the diesel exhaust fluid tank temperature sensor circuit. Possible reduced engine performance. 1678 3031 3 Aftertreatment diesel exhaust fluid tank temperature sensor - Voltage above normal or shorted to high source. High signal voltage or open circuit detected at the diesel exhaust fluid tank temperature sensor circuit. Possible reduced engine performance.
1679 3031 2 Aftertreatment diesel exhaust fluid tank temperature - Data erratic, intermittent, or incorrect. The diesel exhaust fluid tank temperature sensor has indicated a tank temperature too high or too low for the ambient conditions. Possible reduced engine performance. 1682 3362 31 Aftertreatment diesel exhaust fluid dosing unit input lines - Condition exists. The aftertreatment diesel exhaust fluid dosing unit is unable to prime. Possible reduced engine performance. 1683 3363 3 Aftertreatment diesel exhaust fluid tank heater - Voltage above normal or shorted to high source. High signal voltage detected at the aftertreatment diesel exhaust fluid tank heater circuit.
Possible reduced engine performance. 1684 3363 4 Aftertreatment diesel exhaust fluid tank heater - Voltage below normal, or shorted to low source. Low signal voltage detected at the aftertreatment diesel exhaust fluid tank heater circuit. Possible reduced engine performance. 1691 100 18 Aftertreatment diesel oxidation catalyst conversion efficiency - Data valid but below normal operating range - Moderately severe level. The temperature increase across the aftertreatment catalyst is lower than expected. Possible frequent need for aftertreatment regeneration. 1695 3513 3 Sensor supply 5 - Voltage above normal or shorted to high source.
High voltage detected at sensor supply 5 circuit in the oem harness. the engine will operate in limp home mode. 1696 3513 4 Sensor supply 5 - Voltage below normal or shorted to low source. Low voltage detected at sensor supply number 5 circuit in the oem harness. the engine will operate in limp home mode. 1712 3363 18 Aftertreatment diesel exhaust fluid tank heater - Data valid but below normal operating range - Moderately severe level. The aftertreatment diesel exhaust fluid tank heater is unable to thaw the frozen diesel exhaust fluid. Possible reduced engine performance.
