Kia home charger shows E11 and charging stops; may be accompanied by a message about insulation resistance.

Safety first: Low insulation resistance can lead to electric shock. Do not use the charger until the cause is identified.

• 1. Dry the connector: If the charger or cable has been exposed to rain or washing, disconnect and allow the connector and cable to dry thoroughly for at least 24 hours in a warm, dry place.
• 2. Inspect cable jacket: Look for cuts, deep abrasions, or rodent damage along the cable. Any exposed conductor requires cable replacement.
• 3. Test with another EV: If E11 only occurs with one vehicle and other chargers work fine, the issue may be in the vehicle’s onboard charger or inlet. Contact a Kia dealer for vehicle diagnostics.
• 4. Internal inspection (technician): A technician can open the charger (power off) and inspect for water ingress, condensation, or contamination on the output terminals and IMD connections.
• 5. Replace IMD or cable: If the insulation monitoring device is faulty or the cable insulation is compromised, replace the affected component with a Kia-approved part.
