    • Repair or replace any loose or damaged wires.
  • Check ECU Software:
    • Ensure that the ECU control software is up to date.
    • Update the software if necessary.
  • Diagnose CAN Bus Traffic:
    • Use diagnostic tools to analyze CAN bus traffic and identify any abnormalities or faults.
