P2E34Battery Charger A Module Forced Shutdown Voltage High
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E34 is set when the forced shutdown line of charger A reads above its permitted voltage. The usual cause is contact with a battery-fed or switched 12 V wire in the same harness, or an internal leak inside the charger or the commanding module. No manufacturer documents P2E34 publicly. The danger is the reverse of P2E33: on a fail-safe line such as the EmShut input of the EVCC by Watt & Well, where current flowing means normal operation, a line stuck high can no longer carry a stop request. A well-designed control unit therefore distrusts the charger and keeps it disabled instead of risking charging it cannot switch off. The CARB charger rule for plug-in hybrids applies. Low is P2E33, implausible P2E32, charger B high P2E40. Expect no charging through charger A.
