P1EDD on 2014-2015 Cadillac ELR — Battery Charger Converter Input Voltage Sensor 2 Circuit High Voltage
1 vehicles · 1 makes
Most Reported On
P1EDD is an OBD-II diagnostic trouble code meaning “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. This code is most commonly reported on 2014-2015 Cadillac ELR.
