Volvo All Engines (2010 Emissions) Fault Code: SPN 3483 FMI 12 PID: PSID 47 Aftertreatment Diesel Exhaust Fluid (DEF) Regeneration Status

This diagnostic function monitors the systems ability to maintain and regulate the DPF temperatures within acceptable limits based on current conditions like normal operation or during regenerations.

Conditions for diagnostic trouble code (DTC):
1) Regeneration is active (by the relevant operation or by manual regeneration) for 15 minutes
2) The aftertreatment hydrocarbon doser reached its upper fuel delivery limit for temperature adaptation
3) Regeneration efficiency too low

Observable symptoms
1) Regeneration aborted

Probable cause
1) Aftertreatment exhaust gas temperature (EGT) sensors installed in the incorrect location on the aftertreatment diesel particulate filter (DPF)
2) Obstructed/dirty aftertreatment hydrocarbon doser
3) Catalyst failure, Possible excessive sulfur content in the diesel fuel

Volvo All Engines (2010 Emissions) Fault Code: SPN 3483 FMI 15 PID: PSID 47 Aftertreatment Diesel Exhaust Fluid (DEF) Regeneration Status – Least Severe Level

This diagnostic function monitors the systems ability to maintain and regulate the DPF temperatures within acceptable limits based on current conditions like normal operation or during regenerations.

Conditions for diagnostic trouble code (DTC):
1) Automatic Regeneration, Only
2) During regeneration the temperature after the catalyst is too high for the existing conditions, above 800??C, (1472??F)

Observable symptoms
1) Automatic regeneration not possible
2) Regeneration aborted

Probable cause
1) Aftertreatment exhaust gas temperature (EGT) sensors installed in the incorrect location on the aftertreatment diesel particulate filter (DPF)
2) Aftertreatment Hydrocarbon Doser, over-fueling
3) Excessive smoke from the engine (High soot level)
4) Oil contamination, Excessive wear or damage to cylinder liners, piston, piston rings or turbocharger internal seals

Volvo All Engines (2010 Emissions) Fault Code: SPN 3484 FMI 0 PID: Aftertreatment Ignition

The aftertreatment control module (ACM) supplies a pulsed ground signal to activate the ignition coil. The ignition coil is connected to the ignition electrodes by two ignition wires. When activated it supplies 40,000 to 45,000 volts to the ignition electrodes creating an arc that ignites the atomized fuel and air mixture in the aftertreatment diesel particulate filter (DPF) combustion chamber of the aftertreatment DPF.

Conditions for diagnostic trouble code (DTC):
1) Short circuit to battery voltage on Pin: 21 (Ground wire)

Observable symptoms
1) Regeneration not possible

Probable cause
1) Wiring harness between Aftertreatment ignition coil and Aftertreatment Control Module (ACM)
2) Aftertreatment ignition coil
3) Aftertreatment Control Module (ACM)
