Trip Odometer
WARNING: This page is about a different car, the 2003 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
The compass mini-trip computer receives trip odometer information from the Cluster over the PCI bus line. If compass mini-trip computer displays dashes - - instead of the trip odometer value, it is not receiving a PCI bus message for the trip odometer from the cluster. To check out the PCI bus line and the Cluster, use the DRB III(R) scan tool and BODY DIAGNOSTIC PROCEDURES information.
