Ensure the vehicle is parked in a safe area.
Disconnect the charging cable if connected.

2. Inspect Charging Cable

Sub-steps:
1. Examine the entire length of the charging cable for cracks or frayed wires.
2. Check connectors for corrosion or damage.
3. If damaged, replace the charging cable with a compatible Tesla charging cable.

3. Clean Charging Port

2. Inspect the port for bent pins; if pins are bent, consult Tesla service for repair.

4. Check Power Source

Sub-steps:
1. Use a multimeter to check the voltage at the outlet or charging station.
2. If voltage is below 120V at a home outlet, consult an electrician to address the issue.
3. If using a public charging station, try a different station to rule out station-specific issues.

5. Reset System

Sub-steps:
1. Perform a soft reset by holding the left and right scroll wheels on the steering wheel until the screen goes black.
2. Wait for the Tesla logo to appear, then release the scroll wheels.
3. Check if the charging issue persists after the reset.
