Body bus (K-bus)

The body bus (K-bus) is one of the two information links (data line/serial) via a data link to other control units. The body bus is only monitored electrically by the instrument cluster. The body bus is monitored by the basic module (GM). The instrument cluster is also responsible for linking the two bus systems:

• K-bus (body bus)
  
• Diagnosis bus (link to diagnostic socket),
  

(gateway function).
