Solution
1. Preparation
  • Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdrivers, socket set).
  • Ensure the vehicle is parked on a level surface and the ignition is off.
2. Battery Voltage Check
  • Using a multimeter, connect the positive lead to the positive battery terminal and the negative lead to the negative terminal.
  • Ensure the voltage is between 12.4V and 12.7V. If the voltage is low, recharge or replace the battery.
3. Fuse Inspection and Replacement
  • Locate the fuse box (usually in the glove compartment or under the dashboard).
  • Refer to the fuse box diagram to identify the fuses related to the infotainment system (typically labeled as "RADIO" or "INFOTAINMENT").
  • Remove the fuses and inspect them; replace any that are blown with the same amperage rating.
4. Hard Reset of Infotainment System
  • Disconnect the negative battery terminal using a socket wrench.
  • Wait for 10 minutes to allow all systems to reset.
  • Reconnect the negative battery terminal and ensure it is tight.
5. Check Wiring Connections
  • Remove the center console trim to access the head unit.
  • Inspect wiring harness connections to the head unit and amplifier for any loose or damaged wires.
  • Reconnect any loose connections securely.
