Solution

1. Preparation

Gather tools: Diagnostic tool (if available), cleaning supplies (soft cloth, compressed air).
Ensure the vehicle is in park mode and turned off.
Disconnect the charger before any inspection or cleaning.

2. Inspect and Clean Charging Port

Sub-steps:

Sub-steps:
- Inspect the entire length of the charging cable for cuts, frays, or damage.
- Test the charging cable on a different Tesla vehicle to ensure it is functioning properly.
- If the cable is damaged, replace it with a new OEM charging cable.

4. Inspect Charging Station

Sub-steps:
- If using a home charger, check the circuit breaker to ensure it has not tripped.
- Test the outlet with a multimeter to ensure it is providing the correct voltage (240V for Tesla home chargers).
- If using a public charging station, try a different charger if available.

5. Reset Battery Management System

Sub-steps:
