Solution

1. Preparation

Gather necessary tools: multimeter, flashlight, cleaning supplies.
Ensure the vehicle is parked in a safe area and the charging cable is disconnected.
Disconnect power to the home charging station at the circuit breaker for safety.

2. Inspect Charging Cable

Examine the charging cable for fraying or cuts.
If damage is found, replace the charging cable with a compatible Tesla charger.

3. Clean Charging Port

Use a soft cloth to gently clean the charging port on the vehicle.
Inspect for any foreign objects or debris that might obstruct the connection.

4. Test Home Charging Station

Reconnect power to the home charging station by flipping the circuit breaker back on.
Use a multimeter to check the voltage at the outlet; it should read approximately 240V for a Level 2 charger.
If the outlet voltage is incorrect, consult an electrician to address wiring issues.

5. Reset Charging Station

If the charging station has a reset option, perform a reset following the manufacturer’s instructions.
Plug in the charging cable and check for a response on the vehicle's display.
