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 an open circuit or short to ground is detected in the stop light switch circuit system, or when the actual stop light switch status is different from the stop light switch status received from the ETACS-ECU via CAN, the OSS-ECU stores DTC B1136, and displays the power supply system error warning on the multi information display of the combination meter.
