DESCRIPTION:
The ICM display may become black for a short while (<5 seconds) after start-up or during driving. This may be caused by a MOST-net reset. The ICM (Infotainment Control Module) display will then become completely black or the CCM (Climate Control Module) information may be the only visible information. See attached file "TJ22956 ICM.JPG". Any present sound or infotainment system activity may then be interrupted.
If the vehicle is equipped with navigation system that is turned on the HLDF (high level display front) may also become black showing the Volvo iron mark at restart. See attached file "TJ22956 HLDF.JPG".
