P0D00 on Chevrolet by model: symptoms, diagnosis and fix
Early Silverado EVs experience intermittent Level 2 charging interruptions where the vehicle stops charging mid-session or fails to initiate charging. The issue is attributed to EVSE communication protocol timing and software bugs in the onboard charging module. DC fast charging is generally unaffected.
Common Symptoms
- Charging stops unexpectedly
- Charge port light flashing red
- Vehicle fails to start charging
- Charging fault message in app
- Reduced charging speed on Level 2
How to Fix
Update the vehicle software to the latest OTA version — GM has released multiple charging-related fixes. Try a different EVSE/charging station to rule out equipment issues. If the problem persists with multiple chargers, the dealer can diagnose the onboard charger module and CCS communication system. A control module reflash typically resolves the issue.

Frequently asked questions
What does P0D00 mean on a Chevrolet?
P0D00 stands for "Control Pilot Charging Ventilation Switch Circuit/Open." P0D00 is an electric/plug-in hybrid vehicle code in the high-voltage charging family. It relates to the 'control pilot' communication line of the SAE J1772 charging standard, specifically a charging-ventilation switch circuit that the charging system uses to confirm safe conditions before allowing power to flow. The vehicle's control module detected the circuit is open or out of expected range. In practice this usually shows up as a charging fault rather than a drivability problem. On Chevrolet it is documented across 1 model: Silverado EV.
What are the most common causes of P0D00?
The most common causes of P0D00 are: Open or damaged wiring in the charge-port control pilot circuit, Faulty or corroded charge port (EVSE inlet) connector, Defective charging-ventilation switch or pilot circuit sensor, Fault in the onboard charger or charging control module, Poor ground or loose high-voltage connector, Software/calibration issue in the charging system, Faulty EVSE (charging cable/wall unit) reported to the car. The specific cause varies by vehicle.
