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) Incomplete regeneration Probable cause1) Regeneration aborted2) Excessive soot, cleaning required3) Damaged or clogged filter Volvo All Engines (2010 Emissions) Fault Code: SPN 5298 FMI 2 PID: PSID 99 Aftertreatment DOC Conversion Efficiency Volvo All Engines (2010 Emissions) Fault Code: SPN 5298 FMI 18 PID: PSID 99 Aftertreatment DOC Conversion Efficiency – Moderately Severe Level Volvo All Engines (2010 Emissions) Fault Code: SPN 5285 FMI 18 PID: 52...

The aftertreatment control module (ACM) monitors the pressure build up in the diesel exhaust fluid (DEF) dosing system. This diagnostic function checks the time it takes for the DEF dosing pressure to reach more than 650 kPa (94 psi). If the pressure is not reached in 20 minute(s) this DTC will be set. Conditions for diagnostic trouble code (DTC):1) Aftertreatment DEF Dosing Pressure Lower than expected Observable symptoms1) No aftertreatment diesel exhaust fluid (DEF) dosage2) Engine de-rated Probable cause1) Empty tank2) Frozen aftertreatment diesel exhaust fluid (DEF)3) DEF Supply from Aftertreatment DEF Tank disconnected4) Aftertreatment DEF Line(s) Leakage5) Aftertreatment DEF...

When the aftertreatment selective catalytic reduction (SCR) system operates under normal conditions, the aftertreatment control module (ACM) monitors diesel exhaust fluid (DEF) dosing valve duty cycle and DEF pump control value. When the DEF dosing valve duty cycle increases above allowed threshold and the DEF pump control value decreases below expected threshold, the ACM stops DEF dosing and reports a fault. The fault might be indication of electrical failure or blockage in DEF dosing valve or DEF supply line from the DEF tank. Conditions for diagnostic trouble code (DTC):1) The aftertreatment diesel exhaust fluid (DEF) dosing valve has frozen too...

When the aftertreatment selective catalytic reduction (SCR) system operates under normal conditions, the aftertreatment control module (ACM) monitors diesel exhaust fluid (DEF) dosing valve duty cycle and DEF pump control value. When the DEF dosing valve duty cycle increases above allowed threshold and the DEF pump control value decreases below expected threshold, the ACM stops DEF dosing and reports a fault. The fault might be indication of electrical failure or blockage in DEF dosing valve or DEF supply line from the DEF tank.
