Fault Management On Most Network: Notes
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.
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.
