Fault Management On The Most Network: General

The MOST network is monitored by the infotainment control module (ICM). If it detects a fault in the MOST network, a diagnostic trouble code (DTC) is stored in the infotainment control module (ICM). There are different types of diagnostic trouble codes (DTCs) depending on the type of fault. A general rule is that if the light pulse in the MOST network disappears, the entire network stops working.

Fault types which are processed are:

• no communication from a control module
• faulty communication on the MOST network.
