Solution

1. Preparation

Gather necessary tools: multimeter, torque wrench, and any additional charging cables.
Ensure the vehicle is parked on a flat surface and the charging cable is accessible.

2. Inspect Charging Cable

Disconnect the charging cable from both the vehicle and the wall outlet.
Visually examine the entire length of the cable for any cracks or exposed wiring.
Use a multimeter to check continuity through the cable. Replace if defective.

3. Check Wall Outlet

Use a multimeter to measure voltage at the wall outlet; it should read between 110V to 240V depending on the setup.
If no power is detected, reset the circuit breaker and retest the outlet.
If the breaker continues to trip, consult a licensed electrician to inspect the wiring.

4. Verify Charging Station Functionality

Try charging the vehicle at a different location using the same charging cable.
If the vehicle charges successfully at another location, the issue may lie with the home charging setup.

5. Update Vehicle Software

Connect the vehicle to Wi-Fi and check for any available software updates.
Install updates as necessary to ensure all systems are functioning properly.
