Trip Odometer
WARNING: This page is about a different car, the 2003 Chrysler Concorde, 2003 Chrysler 300M, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
The CMTC receives trip odometer information from the Cluster over the PCI bus line. If CMTC displays (- -) instead of the trip odometer value, it is not receiving a PCI bus message for the trip odometer from the Cluster.
