P0E62Battery Charger A Enable Circuit Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P0E62 reports that the enable line of on-board charger A is held at a lower level than its commanded state allows, typically by a short to ground. If the module drives the line high to permit charging, the charger never sees the request. Should the line instead carry a low-active signal, a grounded wire could leave the charger permitted at all times, which is why manufacturers separate low from high. No manufacturer documents P0E62 publicly. GM's 2016 Volt and 2019 hybrid tables cover only the generic enable fault P0E61, using a hardware fault flag at 10.2 V or more, 30 failures in 40 samples and Type B. CARB requires plug-in hybrids to catch charger faults that prevent charging. A shorted enable wire can also overload the driver stage in the commanding module.
