Volvo All Engines (2013 Emissions) Fault Code: P110386 PID: EMS Reductant Injection Valve Circuit Electrical Bank 1 Unit 1

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. Only certain mechanical failure or blockage in the DEF dosing valve or DEF supply line from the DEF tank will result with this fault, it is not a indication of an electrical fault.

Conditions for diagnostic trouble code (DTC):
1) Mechanical fault

Observable symptoms
1) No aftertreatment diesel exhaust fluid (DEF) dosage
2) Possible engine de-rate

Probable cause
1) Aftertreatment diesel exhaust fluid (DEF) dosage valve

Volvo All Engines (2013 Emissions) Fault Code: P110400 PID: EMS Factory Mode

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):
1) Faulty data in program memory

Probable cause
1) Internal fault in electronic control unit (ECU)
