P0E61Battery Charger A Enable Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- P0E61 means the 12 V enable line that wakes or permits the on-board charger has a circuit fault, most often an open. GM documents it codegenau. In the 2016 Volt the VICM watches this charger enable circuit; in the 2019 hybrid tables the HPC2 module does so. The test reads a fault flag reported by the driver hardware and runs when system voltage is at least 10.2 V; 30 failed samples out of 40, taken every 25 ms, set the code as Type B, so the MIL lights after two trips with the fault. GM also uses P0E61 as a blocking condition: while it is active, the high-voltage battery heater test is not run. CARB's charger rule for plug-in hybrids covers exactly such failures. With no enable signal the charger stays off and plug-in charging fails.
