J1939 FMI
Aftertreatment diesel exhaust fluid tank
1677 temperature sensor - Voltage below normal or
3031 shorted to low source. Low signal voltage
4 detected at the diesel exhaust fluid tank
temperature sensor circuit.
Aftertreatment diesel exhaust fluid tank
1678 temperature sensor - Voltage above normal or
3031 shorted to high source. High signal voltage or
3 open circuit detected at the diesel exhaust fluid
tank temperature sensor circuit.
Aftertreatment diesel exhaust fluid tank
temperature - Data erratic, intermittent, or
1679
incorrect. The diesel exhaust fluid tank
3031
temperature sensor has indicated a tank
2
temperature too high or too low for the ambient
conditions.
Aftertreatment diesel exhaust fluid dosing unit
1682
input lines - Condition exists.
3362
The aftertreatment diesel exhaust fluid dosing
31
unit is unable to prime.
Aftertreatment diesel exhaust fluid tank heater -
1683 Voltage above normal or shorted to high
3363 source. High signal voltage detected at the
3 aftertreatment diesel exhaust fluid tank heater
circuit.
Aftertreatment diesel exhaust fluid tank heater -
1684 Voltage below normal, or shorted to low source.
3363 L o w s i g n a l v o l t a g e d e t e c t e d a t t h e
4 aftertreatment diesel exhaust fluid tank heater
circuit.
After treatment diesel oxidation catalyst
1691 conversion efficiency - Data valid but below
100 normal operating range - Moderately severe
18 level. The temperature increase across the
aftertreatment catalyst is lower than expected.
Sensor supply 5 - Voltage above normal or
1695
shorted to high source.
3513
High voltage detected at sensor supply 5 circuit
3
in the oem harness.
Sensor supply 5 - Voltage below normal or
1696
shorted to low source.
3513
Low voltage detected at sensor supply number
4
5 circuit in the oem harness.
Aftertreatment diesel exhaust fluid tank heater -
1712 Data valid but below normal operating range -
3363 Moderately severe level. The aftertreatment
18 diesel exhaust fluid tank heater is unable to
thaw the frozen diesel exhaust fluid.
