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.

If any abnormal data is received from KOS-ECU as a result of the certification communication with KOS-ECU, OSS-ECU stores DTC B1140, and displays the immobilizer certification system inspection warning screen to the multi information display of the combination meter.
