Solution

1. Preparation

Gather tools: OBD-II scanner (if needed), multimeter, and cleaning supplies.
Ensure the vehicle is parked on a flat surface and turned off.
Disconnect the power source from the charging station for safety.

2. Inspect and Clean Charging Components

Inspect Charging Port:
- Open the charging port and visually inspect for any signs of damage or debris.
- Clean the charging port gently with a soft cloth or compressed air to remove any dirt.
Inspect Charging Cable:
- Check the entire length of the charging cable for fraying or damage.
- Clean the connector ends with a damp cloth (ensure they are dry before use).

3. Update Vehicle Software

Connect the vehicle to Wi-Fi.
Navigate to the vehicle settings and check for any available software updates.
Install updates if available, as these may resolve charging issues.

4. Test Charging System

Test Charging Station:
- Connect to a different, known working charging station to see if the vehicle charges properly.
Use a Multimeter:
- Measure voltage at the charging station to ensure it is delivering the correct voltage (typically 240V for Level 2 chargers).

5. Replace Faulty Components

If the charging port or cable is damaged, replace them with OEM parts.
Follow manufacturer specifications for installation and torque values.
