Volvo All Engines (2017 Emissions) Fault Code: P20C100 PID: ACM Reductant Heater “C” Control
Circuit description
This diagnostic trouble code (DTC) indicates a malfunction at the diesel exhaust fluid (DEF) line heater 3. The DEF lines and line connections between the DEF tank and DEF pump are electrically heated by the DEF line heater 3. The DEF line heater 3 is normally OFF and is commended ON by the aftertreatment control module (ACM) when the ambient air temperature (AAT) and DEF tank temperature are below calibrated threshold. The ACM controls the DEF heater 3 by supplying battery voltage to the common voltage supply circuit and grounding control wire (-) circuit using pulse width modulated signal.
Conditions for diagnostic trouble code (DTC)
Open circuit
Probable cause
1) Open circuit, Control wire
2) Open circuit, Common voltage supply
3) Wiring harness
4) Aftertreatment Diesel Exhaust Fluid (DEF) Line Heater 3
