1 vehicles · 1 makes · $150-$2,500 repair
Most Reported On
P101C is an OBD-II diagnostic trouble code meaning “Quick Charging Contactor (N) Stuck / Welded.” The PHEV-ECU checks the state of the negative-side quick-charging contactor against its command. When the contactor remains closed after the ECU has commanded it open (welded or mechanically stuck contacts), the ECU stores P101C. The companion code P101B covers the positive-side (P) contactor. Because a stuck DC-charge contactor is a high-voltage safety hazard, the vehicle restricts motor output and disables quick charging; if P101B and P101C set together the vehicle will not enter 'Ready' at all. This code is most commonly reported on 2014-2021 Mitsubishi Outlander (Outlander PHEV (CHAdeMO-equipped)), with repair costs ranging from $150 to $2,500.
