1. Preparation

Gather tools: multimeter, cleaning cloth, and possibly a replacement charging cable.
Ensure the vehicle is parked in a safe location and the charging equipment is easily accessible.

2. Inspect Charging Cable

Disconnect the charging cable from both the vehicle and the wall outlet.
Visually inspect the cable for any frays, kinks, or damage.
If damage is found, replace the charging cable with a new one compatible with Tesla.

3. Check and Reset Home Charging Station

Locate the circuit breaker for the charging station and turn it off for 10 seconds, then turn it back on to reset.
Ensure that the charging station is properly connected to the power source and that there are no blown fuses.
If the station has a reset button, press it to reset the unit.

4. Clean Charging Port

Using a soft cleaning cloth, gently clean the charging port on the vehicle.
Ensure that no foreign objects or debris are obstructing the port.
Inspect the port's pins for any corrosion or damage; if corrosion is present, use electrical contact cleaner to gently clean the contacts.

5. Test Charging

Reconnect the charging cable to both the vehicle and the wall outlet.
Monitor the charging indicator on the vehicle and the Tesla app for any changes.
If charging initiates, monitor for any error messages on the display.
