>>A<< OSS-ECU INSTALLATION
When the OSS-ECU is replaced, the mode is shifted to the special operation mode, and the system works as follows:
  • When the electric motor switch is pressed, the power supply mode of the vehicle changes without key certification.
  • The plug-in hybrid system cannot be operated.
  • While turning the vehicle power on, the LED of the electric motor switch flashes in blue.
  • After the OSS-related devices including OSS-ECU are registered and plug-in hybrid system operation is possible, the special operation mode will be cancelled automatically by operating the electric motor switch.
  • Check that the special operation mode cancellation is completed by checking the diagnostic trouble code, by checking whether the electric motor switch LED is flashing or not, and by checking whether the plug-in hybrid system can be operated or not.
