Navigation System: Diagnostics

The diagnostic socket allows the exchange of information between the navigation system components and DIS. The diagnostic socket is located in the driver's footwell. A dedicated diagnostic bus is connected between the socket and the instrument cluster and allows the retrieval of diagnostic information and coding of certain functions to be performed using DISplus. The instrument cluster forms the gateway for the K-bus link to the navigation components. The cluster translates diagnostic messages from DISplus into K-bus messages recognized by the navigation system components.
