Technical Description (Comment)
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 the signal from each ECU is received via the CAN communication, the combination meter illuminates the corresponding display light or warning light, or has the multi-information display to display corresponding information.
If the lights do not illuminate or the multi-information display does not display normally, the wiring harness and connector(s) in the CAN bus lines, each ECU (that sends a signal) or the combination meter may have a problem.
