P0D57 Proximity Detection Circuit A Range/Performance

Check engine lightOn
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

P0D57 means the plug-present signal of proximity circuit A is electrically within limits but its value or behaviour does not fit the situation, for instance a level between the defined states for plugged, unplugged and latch pressed. FCA uses the code on the Chrysler Pacifica plug-in hybrid: bulletins 08-044-20 (2017) and 08-042-20 (2018) list P0D57 with control pilot codes P0CF3 and P0CF4 behind an illuminated MIL and cure it by reflashing the hybrid control processors HCP and AHCP. FCA publishes no thresholds. The J1772 proximity circuit relies on defined resistor steps, so worn inlet contacts or an off-standard charging cable can shift the reading. Hard short circuits are P0D58 and P0D59.

Likely causes

Hybrid control software needs update (FCA HCP/AHCP)
Worn or contaminated proximity contact shifts the resistance
Charging cable or adapter with off-standard proximity resistor

Symptoms

  • MIL on (FCA)
  • Charging starts unreliably or not at all
  • Plug status shown incorrectly
