Solution

1. Preparation

Gather necessary tools including an OBD-II scanner, multimeter, and a flashlight.
Ensure the vehicle is parked safely and turned off.

2. Inspect Charging Equipment

Charging Cable:
- Examine the cable for any fraying or cuts.
- If damaged, replace the charging cable.
Charging Port:
- Clean the charging port using a soft cloth and inspect for any physical damage.
- If damaged, the charging port may need to be replaced.

3. Test the Wall Outlet

Using a Multimeter:
- Set the multimeter to measure AC voltage.
- Plug the multimeter probes into the outlet where the charger is connected.
- Ensure the voltage reading is between 110-120V (for standard outlets) or 240V (for dedicated EV chargers).
- If the outlet is not providing power, consult an electrician to check the wiring.

4. Check Circuit Breaker

Inspect the circuit breaker panel:
- Identify the breaker for the charging station and ensure it is in the ON position.
- If tripped, reset the breaker and try charging again.
- If it trips again, there may be an issue with the circuit that requires professional attention.

5. Review Vehicle Settings

Access the Tesla's settings from the touchscreen:
- Navigate to "Charging" and ensure that charging is enabled.
- Check that Charge Limit is set appropriately.
- Look for any software updates or alerts that may need attention.
