When OSS-ECU is in the special operation mode (ECU is new), OSS-ECU sets the diagnosis code No.B1166, and flashes the indicator of engine switch in green. When the engine switch is pressed, only the power supply mode of the vehicle can be changed without key certification.
note
After the chassis number and key code are written, the operation mode shifts to the normal operation mode when the certification communication becomes valid at an engine switch operation, and the diagnosis code No.B1166 is erased.
