Instrument Cluster

WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster is on the SCP communication network. It is an analog face cluster with a digital odometer. The instrument cluster displays a variety of information. If one of the bus wires becomes shorted to ground or voltage, or if some but not all termination resistors are lost, communications can continue at a degraded level. Check the SCP circuits 915 (PK/LB) and 914 (TO/OG) between the instrument cluster C220a and the DLC C251. Total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the SCP network, damage to the DLC C251, damage to the instrument cluster C220a, or a problem in the in-line connector.
