P0E63Battery Charger A Enable Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P0E63 is the high-level counterpart: the enable signal to charger A sits above the level its commanded state allows, for instance because it touches a 12 V feed. In practice the charger may then be woken although no charging is requested, which can drain the 12 V battery while parked, or it may ignore a switch-off command. No manufacturer documents P0E63 publicly. GM documents only the generic enable fault P0E61 for the 2016 Volt (VICM) and in the 2019 hybrid tables (HPC2), evaluated via a hardware fault flag with 30 failures in 40 samples as Type B; separate low and high codes are not listed there. CARB counts any charger fault that disturbs charging as one a plug-in hybrid must detect. A wire chafed against a powered harness or an internal short in the charger are the usual suspects.
