Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, basic hand tools (screwdrivers, socket set), and a replacement fuse if necessary.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Battery Voltage Check

Use a multimeter to measure the battery voltage.
If the voltage is low, charge or replace the battery before proceeding.

3. Fuse Inspection

Locate the fuse box for the infotainment system (usually found under the dashboard or in the engine compartment).
Remove the relevant fuse and inspect it visually. Replace with a new fuse if blown (typically 10A or 15A).
Reinstall the fuse and check if the system functions properly.

4. Hard Reset

Disconnect the negative terminal of the battery using a socket wrench.
Wait for at least 5 minutes to allow the system to reset.
Reconnect the negative terminal and ensure it is tightened properly.

5. Software Update

If available, download the latest software update from the Toyota website or dealer.
Follow the instructions provided to install the update onto a USB drive.
Insert the USB drive into the infotainment system and navigate to the update settings to complete the installation.

6. Inspect Wiring and Connections

Remove the infotainment unit from the dashboard by carefully prying it out with trim removal tools.
Inspect the wiring harness and connectors for any signs of damage or corrosion.
Clean connectors with electrical contact cleaner if necessary and ensure all connections are secure.
Reinstall the unit and test the system.
