Diagnostic Function
WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
When OSS-ECU is in the special operation mode (ECU is new), OSS-ECU stores DTC 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 VIN 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 DTC B1166 is erased.
