P2E8C code meaning
Battery Charger B Charge Sequence Signal 1 Circuit High
What P2E8C means
Charge sequence signals 1 and 2 belong to DC fast charging to CHAdeMO, used for example on the Nissan Leaf, the Mitsubishi i-MiEV and the Outlander PHEV. Signal 1 runs over connector pin 2: the station closes its switch d1 and applies 12 V to the line, which tells the car it is ready and starts the CAN dialogue. P2E8C means the vehicle sees this line high when it should not, for instance with no station connected or after the station has opened d1 once a session is over, or the level exceeds the allowed range. Likely reasons are a short to a 12 V source in the harness or inlet, or a faulty input stage. No manufacturer documents P2E8C publicly. The car can then no longer trust the start and stop handshake and usually refuses DC charging. The low counterpart is P2E8D.
P2E8C at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2E8C
- DC fast charging refused or ending with an error
- AC charging continues to work
- Charging fault message in the cluster
Common causes of P2E8C
- Most likelySequence signal 1 line shorted to a 12 V source
- PossibleMoisture or debris in the DC inlet bridging pins
- PossibleFaulty input stage in the evaluating control unit
- Less likelyStation switch d1 not opening at the end of a session
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E8C means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 8C | The exact fault in that area. |
What to do next
- Note P2E8C 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 P2E8C
What does P2E8C mean?
P2E8C means "Battery Charger B Charge Sequence Signal 1 Circuit High". Charge sequence signals 1 and 2 belong to DC fast charging to CHAdeMO, used for example on the Nissan Leaf, the Mitsubishi i-MiEV and the Outlander PHEV. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E8C?
P2E8C does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2E8C fail an emissions test?
P2E8C 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 P2E8C to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2E8C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
