    • Ensure that the ECU control unit is functioning correctly. Recalibrate or replace the unit if necessary.
  • Check CAN BUS Communication:
    • Test the CAN BUS network for proper communication and address any faults detected.
  • Consult Technical Support:
    • If the issue persists, consult technical support for further diagnostics and assistance.
