P2D85 is for an input current reading of charger B that lies within the electrical limits yet cannot be true. No manufacturer documents P2D85 publicly. Its A-side model P0D39 shows the usual test, a check of the zero point while no current should flow: Mitsubishi sets it on the 2022 Outlander PHEV if at least 1.5 A shows up for 2 s while charging is not yet permitted by the PHEV control unit; GM's 2011 Volt module reacts once the offset hits 5.4 A in 512 out of 640 ms. CARB wants such rationality faults filed separately from circuit faults, and allows sensors mounted on a control unit's circuit board to share one code for circuit and range faults. A drifting sensor makes the charger misjudge its power. Hard low or high faults are P2D83 and P2D84.

Likely causes

Zero-point drift of the charger B current sensor
Real residual current through a defective input stage while charging is not released
Calibration or software fault of the charger

Symptoms

  • Charging refused or stopped soon after plugging in
  • Charging power lower than expected
