Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, and a clean cloth.
Ensure the vehicle is in "Park" mode.

2. Inspect Charging Cable

Sub-steps:
- Disconnect the charging cable from both the vehicle and the charging station.
- Visually inspect the cable for any physical damage, fraying, or corrosion at the connectors.
- Clean the connectors with a cloth to remove any debris or corrosion.
Safety Warning: Ensure the charging station is powered off while inspecting the cable.

Sub-steps:
- Open the charging port door.
- Inspect for any debris or obstructions inside the charging port.
- Clean the charging port gently with a dry cloth.
- Inspect for any signs of physical damage or bent pins inside the charging port.

4. Test Charging Station

Sub-steps:
- Plug the charging cable back into the charging station and vehicle.
- Use a multimeter to check the voltage at the charging outlet to ensure it is within the range specified for the Tesla Model S (typically around 240V for Level 2 charging).
- If the voltage is incorrect, contact the charging station provider for assistance.

5. Reset the Vehicle’s Charging System

Sub-steps:
- Perform a soft reset of the vehicle by holding down the two scroll wheels on the steering wheel until the touchscreen reboots.
- After the reboot, reconnect the charging cable and attempt to charge again.
