Solution
1. Software Update
  1. Navigate to the ‘Software’ tab on the touchscreen.
  2. Check for any available updates and follow on-screen instructions to install.
  3. Restart the vehicle after the update is complete.
2. Inspect the 12V Battery
  1. Preparation: Turn off the vehicle completely and ensure safety protocols are followed.
  2. Locate the 12V Battery: Remove any trim panels if necessary to access the battery.
  3. Measure Voltage: Use a multimeter to check the battery voltage. It should be around 12.6 volts when fully charged.
    • If the voltage is below 12 volts, replace the battery.
  4. Reconnect: Ensure that all connections are tight and free of corrosion.
3. Inspect Electrical Connections
  1. Visual Inspection: Check all visible wiring and connectors for damage or corrosion.
  2. Tighten Connections: Use a socket set to tighten any loose connections.
  3. Clean Terminals: If corrosion is present, clean the terminals using a wire brush.
4. Clear Diagnostic Trouble Codes
  1. Connect the OBD-II scanner to the vehicle's diagnostic port.
  2. Follow the scanner instructions to read and clear any DTCs.
  3. Note any persistent codes for further investigation.
5. Test Touchscreen and Electrical System
  1. Power on the vehicle and observe the touchscreen for any flickering.
  2. Perform a soft reset of the touchscreen by holding down the two scroll wheels on the steering wheel until the screen reboots.
  3. Monitor the vehicle's electrical systems for any unusual behavior.
