Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Disconnect the 12V battery for safety.
Tools Required: Socket set, multimeter, OBD-II scanner.

2. Battery Inspection

Inspect connections: Remove the battery terminal covers and check for corrosion.
- Clean any corrosion with a wire brush and apply dielectric grease.
Check battery voltage: Reconnect the battery and use a multimeter to measure voltage.
- If voltage is below 12.4 volts, replace the battery.

3. Key Fob Troubleshooting

Replace key fob battery: Open the key fob and replace the battery with a new one (typically CR2032).
Test key fob: Attempt to start the vehicle again with the reassembled key fob.

4. High-Voltage Battery Check

Inspect the BMS: Use an OBD-II scanner to check for any fault codes related to the high-voltage battery management system.
- Address any error codes that appear, which may involve contacting Tesla service if necessary.

5. Computer Reset
