Battery Charger Input Circuit Intermittent/Erratic

Check these first

• A loose or backed-out pin in the battery charger input connector
• A chafed input wire rubbing against the charger housing
• A charge port or inlet that loses contact under vibration
• Moisture in the charger input connector

What to do next

1. Watch the charger input voltage while wiggling the input harness
2. Inspect the input connector for loose pins and corrosion
3. Check the input wiring for rubs and chafing
4. Try a known-good charge cable
5. Replace the charger input harness or charger assembly if the fault stays
6. Clear the code and retest
