Solution
1. Preparation
  • Ensure the vehicle is parked and the engine is off.
  • Gather necessary tools: OBD-II scanner (if software update is needed), smartphone for testing.
  • Make sure the mobile device is fully charged.
2. Restart Infotainment System
  • Turn off the vehicle completely and remove the key from the ignition.
  • Wait for at least 5 minutes before restarting the vehicle.
  • Turn on the ignition and check if the infotainment system boots up properly.
3. Delete and Re-pair Devices
  • Go to the Bluetooth settings on the vehicle’s infotainment system.
  • Select "Settings" or "Bluetooth" and find the list of paired devices.
  • Select each device and choose "Delete" or "Forget".
  • On the mobile device, go to Bluetooth settings and remove the vehicle from the paired devices list.
  • Restart both the infotainment system and the mobile device.
4. Software Update
  • Check the Toyota website or the vehicle’s manual for instructions on how to perform a software update.
  • If an update is available, use an OBD-II scanner or USB drive to upload the latest software to the vehicle’s infotainment system.
5. Check Fuses
  • Locate the fuse box in the Toyota Highlander (typically found under the dashboard or in the engine compartment).
  • Using the fuse diagram, check the fuse associated with the infotainment system.
  • If the fuse is blown, replace it with a new fuse of the same amperage.
