P2E3EBattery Charger B Module Forced Shutdown Voltage Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E3E is the charger B version of P2E32: the forced shutdown signal of the second charger is electrically in range but its behaviour is implausible. Examples are a shutdown request that the charger ignores, or a level that changes state without a matching command, so the control unit can no longer trust its hardwired off-switch for path B. No manufacturer documents P2E3E or the underlying circuit publicly. What such a line is for can be seen at Watt & Well, whose EVCC controller ends a charging session in hardware as soon as current in its EmShut loop vanishes. CARB demands that plug-in hybrids detect charger faults that prevent or degrade charging. Its low and high faults are P2E3F/P2E40. Expect charger B to be locked out; a first charger may keep charging at reduced power.
