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 selector lever is operated, the selector lever position signal from the transmission range switch is sent to the TCM. ECM receives the selector lever position signal from the TCM via the CAN bus line.
