When the KOS&OSS-ECU is replaced, the mode is shifted to the special operation mode, and the system works as follows:

  • When the engine switch is pressed, the power supply mode of the vehicle changes without key certification.
  • The lock/unlock control of the electric steering lock is not performed.
  • The engine cannot be started.
  • While turning the vehicle power on, the LED of the engine switch flashes in green.
  • After the OSS-related devices including KOS&OSS-ECU are registered and engine start is possible, the special operation mode will be cancelled automatically by operating the engine switch.
  • Check that the special operation mode cancellation is completed by checking the diagnosis code, by checking whether the engine switch LED is flashing or not, and by checking whether the engine can be started or not.
