P2E35Battery Charger B Enable Circuit/Open
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E35 covers the enable line of charger B, the hardwired 12 V signal that wakes the charger or allows it to work, and reports a general circuit fault, usually an open. No manufacturer documents P2E35 publicly. The A-side code P0E61 is documented by GM: the 2016 Volt (VICM) and the 2019 hybrid tables (HPC2) evaluate a fault flag from the line driver at 10.2 V system voltage or more, 30 bad samples out of 40 at 25 ms, Type B. Holley's 30-8405 charger unit shows why the line counts: the charger only runs with 12 V on its wake-up pin, and without it even its CAN stays silent. Specific level faults are P2E36 and P2E37, plausibility P2E38. With an open line charger B stays asleep; a car with a second charger may still charge slowly through the first.
