Elapsed Time
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 a PCI bus message containing elapsed time information. If the CMTC displays dashes (- -) instead of elapsed time, it is not receiving a PCI bus message for the elapsed time from the BCM. To diagnose the PCI bus line and the BCM, see BODY CONTROL MODULES - LIBERTY article.
