3. Battery Reset
  • Disconnect the negative terminal of the battery using a socket wrench.
  • Wait for at least 5 minutes to ensure a complete reset.

4. Wiring Inspection
  • Remove the trim panel surrounding the infotainment unit using a flathead screwdriver.
  • Unscrew the infotainment unit from its mounting bracket.
  • Inspect the wiring harness for corrosion, damage, or loose connections.
  • Reconnect any loose wires and secure the harness properly.
5. Software Update
  • Connect the OBD-II scanner to the vehicle’s diagnostic port.
  • Check for any fault codes that may indicate software issues.
