How to diagnose and fix P1EDD: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Cadillac ELR · 2014–2015
GM PIC6015A and PIC6076 cover bounded ELR no-charge and Service High Voltage Charging System paths. A cord, charging station, pilot-signal fault, cracked or water-affected receptacle, or an applicable HPCM2 calibration can produce the concern; the bulletins do not establish universal onboard-charger failure.
Common Symptoms
- Vehicle will not charge
- Service High Voltage Charging System message
How to Fix
Have a qualified technician record DTCs and freeze-frame data, rule out the cord and charging infrastructure, inspect the charge receptacle for cracks or water intrusion, and apply the current GM diagnostic or HPCM2 programming path when its criteria are met. Do not order charging hardware from this card.

Frequently asked questions
What does P1EDD mean?
P1EDD stands for "Battery Charger Converter Input Voltage Sensor 2 Circuit High Voltage." General Motors manufacturer-specific code documented on the 2014-2015 Chevrolet Volt and Cadillac ELR. The onboard battery charger module reports its internal bulk voltage above roughly 464 volts DC on the second input voltage sensor circuit. The driver typically sees a 'Service High Voltage Charging System' message on the Driver Information Center and the vehicle may refuse to charge. These are internal battery charger diagnostics that still require the vehicle's AC supply to be in the proper range to run correctly, so the incoming AC side and the charge port are checked before the charger is condemned. GM has issued a service bulletin covering this message with P1EDD/P1EDC on these models, so check for an applicable bulletin or software update before replacing parts.
What are the most common causes of P1EDD?
The most common causes of P1EDD are: Applicable GM service bulletin or control module software update not yet performed — check before replacing any parts, AC supply problem at the EVSE or wall circuit feeding the charger (out-of-range AC voltage causes the internal diagnostics to misreport), Cracked or damaged charge port receptacle — GM's procedure has you confirm a 30-second charge on any EVSE, then remove and inspect the receptacle for cracks on the back side, Damaged, corroded, or backed-out wiring and connector pins on the charger input circuit, Faulty onboard battery charger module / power inverter assembly. The specific cause varies by vehicle.
How much does it cost to fix P1EDD?
Repair costs vary widely depending on the root cause and vehicle.
