P2E35 code meaning
Battery Charger B Enable Circuit/Open
What P2E35 means
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.
P2E35 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2E35
- Charger B does not wake when the cable is plugged in
- Charging slower than usual or not at all
- Charging system warning message
Common causes of P2E35
- Most likelyBroken enable wire or backed-out terminal
- PossibleSignal connector at charger B not fully latched
- Less likelyFailed enable driver in the commanding module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E35 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 35 | The exact fault in that area. |
What to do next
- Note P2E35 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2E35
What does P2E35 mean?
P2E35 means "Battery Charger B Enable Circuit/Open". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E35?
P2E35 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2E35 fail an emissions test?
P2E35 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2E35 to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2E35 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
