Solution

1. Preparation

Gather necessary tools: screwdriver set, multimeter, OBD-II scanner.
Disconnect the vehicle's battery to prevent any electrical shorts during the repair.

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and locate the fuse for the infotainment system (refer to the diagram on the fuse box cover).
Use a fuse puller or needle-nose pliers to remove the fuse.
Inspect the fuse: if the wire inside appears broken or melted, replace it with a new fuse of the same amperage (typically 10A or 15A).
Reinstall the fuse and cover.

3. Check and Secure Connections

Remove the trim panel surrounding the infotainment unit using a flathead screwdriver or trim removal tool.
Unscrew and carefully pull out the infotainment unit.
Inspect the connectors on the back of the unit for any signs of corrosion or loose connections.
Reconnect any loose cables securely, ensuring they click into place.

4. Reconnect Battery and Test

Reconnect the vehicle’s battery terminals, ensuring a secure fit.
Turn on the ignition and check if the infotainment system powers on.
If it remains off, proceed to the next step.

5. Software Update (if applicable)

If the system still does not function, check for software updates via the Toyota website or contact a dealership for assistance.
If an update is available, follow the dealership's instructions on how to perform the update.
