Distance To Empty
WARNING: This page is about a different car, the 2002 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
The CMTC receives distance to empty information from the BCM over the PCI bus line. If the CMTC displays a dash (-) instead of a distance to empty value, it is not receiving a PCI bus message for the distance to empty from the BCM. To diagnose the PCI bus line and the BCM, see BODY CONTROL MODULES - LIBERTY article.
