EV Charger Error

Pilot Signal Error (Delta)

Updated March 2026

Share

This is general guidance based on the ChargeX MREC standard. Actual charger behavior varies by manufacturer and firmware version. Always follow on-screen instructions and contact the charging network if you are unsure.

Warning

The Delta charger is not receiving the correct control pilot signal from the vehicle. The pilot signal is how the car and charger negotiate charging parameters.

What to do

  1. Unplug and re-insert the connector firmly
  2. Check the connector for bent pins or debris
  3. Try a different connector or charger
  4. If this happens with your vehicle on multiple chargers, the vehicle's charge port may need inspection

Who's responsible?

  • This may be a vehicle issue
  • This is likely a charger hardware issue
