Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, cleaning supplies (compressed air, soft cloth).
Ensure the vehicle is parked on a level surface and safely powered off.
Disconnect any charging equipment from the vehicle.

2. Clean Charging Port

Sub-step 1: Use compressed air to blow out any debris or dirt from the charging port.
Sub-step 2: Wipe the interior of the charging port with a soft cloth to remove moisture or residues.
Sub-step 3: Inspect the charging port pins for any signs of corrosion or damage.

3. Inspect Charging Cable

Sub-step 1: Examine the charging cable for fraying, cuts, or kinks.
Sub-step 2: Test the cable with another Tesla vehicle, if possible, to ensure it is functioning correctly.
Sub-step 3: Replace the cable if it is found to be faulty.

4. Check Power Supply

Sub-step 1: Use a multimeter to measure the voltage at the charging station or wall connector.
Sub-step 2: Ensure the voltage is within the acceptable range (typically 240V for Level 2 chargers).
Sub-step 3: If the voltage is incorrect, troubleshoot the power supply source (circuit breaker, outlet, etc.).

5. Reset Charging System

Sub-step 1: Perform a soft reset of the vehicle to clear any temporary glitches.
Sub-step 2: If issues persist, consider a hard reset by disconnecting the 12V battery for a few minutes (ensure proper precautions).
