P0D58 on Cadillac by model: symptoms, diagnosis and fix
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 P0D58 mean on a Cadillac?
P0D58 stands for "Proximity Detection Circuit A Low." A plug-in hybrid and EV charging code that sets when the voltage on the charge port proximity detection circuit falls below the expected threshold. The proximity circuit is how the vehicle knows a charging cable is physically latched into the port, so a fault here can leave the car unable to charge and, on some vehicles, can affect shifting out of Park because the car believes a cable is still attached. GM publishes a diagnostic procedure for P0D58/P0D59 on the Chevrolet Volt, and charge port receptacle cracking with water intrusion is a commonly reported cause on the Volt and Cadillac ELR. Some manufacturers reuse this code number differently, so confirm against service information for your vehicle. On Cadillac it is documented across 1 model: ELR.
What are the most common causes of P0D58?
The most common causes of P0D58 are: Water intrusion or corrosion in the charge port receptacle, Cracked charge port receptacle housing, Damaged or shorted proximity signal wiring, Loose or backed-out connector terminals at the charge port, Faulty charging cable / EVSE latch switch, Failed on-board charger or charge port control module. The specific cause varies by vehicle.
How much does it cost to fix P0D58 on a Cadillac?
Repair costs vary widely with the root cause and Cadillac model; each issue on this page carries its own estimate where one is published.
