Volvo All Engines (2013 Emissions) Fault Code: P109541 PID: EMS Aftertreatment Control Unit

Circuit description
This diagnostic trouble code (DTC) detects faults in the main software. Faulty main software can result in engine no start symptoms.

Conditions for diagnostic trouble code (DTC)
VIN is not available

Probable cause
1) Programming sequence interrupted

Volvo All Engines (2013 Emissions) Fault Code: P10AD13 PID: ACM Reductant Pump “A” Control Low Side

Circuit description
The aftertreatment control module (ACM) uses the aftertreatment diesel exhaust fluid (DEF) dosing pressure sensor value to adjust and maintain DEF pressure at the DEF dosing valve by controlling DEF pump speed. If the pressure decreases below expected value when the pump is in initial pressure build-up mode or if the pressure increases above expected value when pump is in idle speed mode, the ACM considers DEF pressure outside of normal operating range and indicates a malfunction in a DEF dosing pressure sensor.

Conditions for diagnostic trouble code (DTC)
Open circuit

Observable symptoms
No aftertreatment diesel exhaust fluid (DEF) dosage

Probable cause
1) Connector
2) Wiring harness
3) Aftertreatment Diesel Exhaust Fluid (DEF) Pump
4) Aftertreatment Control Module (ACM)

Detailed information
Possible engine de-rate

Volvo All Engines (2013 Emissions) Fault Code: P10C013 PID: EMS Volvo Compression Brake (VCB) Control “2” Circuit

Conditions for diagnostic trouble code (DTC):
1) Output not activated

Observable symptoms
1) Reduced engine braking since the compression brake cannot be activated
2) Reduced gear selection performance for some automatic transmissions

Probable cause
1) Open circuit in the voltage supply
2) Open circuit in the compression brake solenoid valve

Volvo All Engines (2013 Emissions) Fault Code: P10CE97 PID: ACM Reductant Return No Flow Detected

The aftertreatment control module (ACM) uses the aftertreatment diesel exhaust fluid (DEF) dosing pressure sensor value to adjust and maintain DEF pressure at the DEF dosing valve by controlling DEF pump speed. If the pressure decreases below expected value when the pump is in initial pressure build-up mode or if the pressure increases above expected value when pump is in idle speed mode, the ACM considers DEF pressure outside of normal operating range and indicates a malfunction in a DEF dosing pressure sensor.

Conditions for diagnostic trouble code (DTC):
1) ACM_ Urea Pressure above 500 kPa

Observable symptoms
1) Aftertreatment DEF Pump Bleed Orifice

Probable cause
1) Restricted orifice in the aftertreatment fuel manifold
2) Damaged hoses and/or connections
3) Aftertreatment Diesel Exhaust Fluid (DEF) Pump

Volvo All Engines (2013 Emissions) Fault Code: P10E100 PID: EMS Particulate Filter Differential Pressure Critically High

The function identifies and indicates malfunction of the aftertreatment diesel particulate filter (DPF) by analyzing the pressure drop over the aftertreatment DPF. This is done by making a check for deviation between sensor value and a model pressure drop. In some extreme cases the engine will derate.

Conditions for diagnostic trouble code (DTC):
1) High differential pressure across the filter (> 35 kPa (5 psi / 10.3 in-Hg))

Observable symptoms
1) Low Power
2) Medium to high derate

Probable cause
1) Excessive smoke from the engine
2) Aftertreatment diesel particulate filter (DPF) is loaded with soot
3) Aftertreatment diesel particulate filter (DPF) is loaded with ash
4) Incomplete regeneration, driver has not allowed regeneration to complete
5) Regeneration inhibited, driver has not allowed regeneration to take place
6) Charge air system leakage
7) EGR System Faulty
8) Aftertreatment DPF Differential Pressure Sensor
