Normal Operation
The navigation system module communicates with the diagnostic tool through the standard corporate protocol (SCP) communication network, circuits
914 (TN/OG) and 915 (PK/LB). Check circuits 914 (TN/OG) and 915 (PK/LB) between the navigation system module C2279a and the data link
connector (DLC) C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in one of the
SCP communications circuits, damage to the DLC C251, damage to the navigation system module C2279a, or a problem in an in-line connector.
