Solution

1. Preparation

Gather necessary tools: multimeter, cleaning supplies (soft cloth, isopropyl alcohol), and an OBD-II scanner (if required).
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the charging cable from the wall outlet and the vehicle.

If necessary, lightly moisten the cloth with isopropyl alcohol to remove stubborn debris.
Check for any bent pins or foreign objects inside the charging port and remove them carefully.

3. Test Charging Cable

Use a multimeter to check the continuity of the charging cable. Set it to the resistance setting and test the prongs for continuity.
If the charger is faulty, replace it with a compatible charging cable.

4. Reset Vehicle Systems

Power off the vehicle completely by holding down the brake pedal and pressing the 'Power Off' button on the screen.
Wait for at least two minutes before restarting the vehicle to reset the onboard systems.

5. Update Software

Connect the vehicle to Wi-Fi and check for software updates via the touchscreen.
If an update is available, follow the prompts to install it, which may resolve any charging-related software issues.

6. Check Circuit Breaker

Locate the circuit breaker for the charging station and ensure it is in the "On" position.
If it is tripped, reset it and attempt charging again.
