P2D62 code meaning
Battery Charging System Negative Contactor C Circuit
What P2D62 means
P2D62 is the collective electrical code covering minus contactor C, which connects the return conductor of the third charging path to the traction battery. Neither the code nor the meaning of C is documented by any manufacturer. Separate switches in both poles are common on charging paths because only then can the inlet be fully isolated, and diagnosing the pair needs one pole held closed while the other is tested: a Hyundai quick-charge patent checks the plus relay first and then the minus relay against the voltage at the charging inlet, so a minus-side fault is pinned down separately. Under CARB, a plug-in hybrid must flag charging faults that disable or limit charging. Welded and non-closing cases are P2D63/P2D64, driver faults P2D65–P2D68, the plus side P2D5B. The charging mode via C is typically disabled.
P2D62 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor1 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2D62
- One charging mode unavailable
- Charging warning in the cluster
- Driving unaffected
Common causes of P2D62
- PossibleCoil of minus contactor C open or shorted
- PossibleWiring or plug fault on the minus contactor
- Less likelyModule output stage or software
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2D62 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 62 | The exact fault in that area. |
What to do next
- Note P2D62 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 P2D62
What does P2D62 mean?
P2D62 means "Battery Charging System Negative Contactor C Circuit". P2D62 is the collective electrical code covering minus contactor C, which connects the return conductor of the third charging path to the traction battery. It is a generic code, so it means the same on every make.
Is it safe to drive with P2D62?
P2D62 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2D62 fail an emissions test?
P2D62 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 P2D62 to fix?
Difficulty: workshop only. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P2D62 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
