P2E2D is set when the 12 V feed of the control board in on-board charger A stays below its lower limit. The usual suspects sit outside the charger: a discharged or failing 12 V battery, a DC/DC converter that is not keeping the network up, a blown fuse in the feed, or resistance in supply or ground wiring that eats voltage under load. For orientation, Mitsubishi's Outlander PHEV accepts its charger's supply only between 10 and 16 V before checking the internal rails (P0D67); the limit behind P2E2D is not published, and no manufacturer documents the code. CARB requires plug-in hybrids to catch charger faults that block charging. Too high is P2E2E, implausible P2E2C, low AC input P0D27. The car often still drives, but charging may fail.

Likely causes

Discharged or aged 12 V battery
Blown fuse or failed relay in the charger supply
High resistance in supply or ground wiring
DC/DC converter not maintaining the 12 V network

Symptoms

  • Plug-in charging refused or interrupted
  • Further low-voltage faults in other modules
  • Charging status display behaves erratically
