Solution

1. Preparation

Tools Required: None specifically for preparation.
Ensure the vehicle is parked in a safe location, and the ignition is in the "On" position.

2. Restart Infotainment System

Press and hold both scroll wheels on the steering wheel until the touchscreen goes black and the Tesla logo appears.
Wait for the system to reboot completely, which usually takes about 1-2 minutes.

3. Delete and Re-Pair Devices

Navigate to the Bluetooth settings on the Tesla touchscreen.
Select any paired devices and choose "Forget" or "Remove" to clear them.
On your mobile device, go to Bluetooth settings and remove the Tesla from the list of paired devices.
Attempt to re-pair the mobile device by selecting "Add New Device" on the Tesla's Bluetooth menu.

4. Software Update

Go to "Controls" > "Software" on the Tesla touchscreen.
If an update is available, follow the prompts to download and install it.
Allow the vehicle to reboot after the update is installed.

5. Inspect Bluetooth Module Fuse

Locate the fuse box in the Tesla Model S (typically under the dashboard or in the frunk).
Use a fuse puller or needle-nose pliers to check the fuse associated with the Bluetooth module (refer to the owner’s manual for specific fuse location).
If the fuse is blown, replace it with a new fuse of the same amperage.
