Audio System (G2196497): Description: Clock
The Body Control Module/Gateway Module (BCM/GWM) assembly contains the master clock functionality. Other vehicle infotainment system modules that require clock functionality use the time supplied from the BCM/GWM assembly.
The clock is available to any control module that is connected to an interconnecting bus system.
The clock display is configurable to show in AM/PM or 24 hour format. Midnight is shown as 12:00 AM or 00:00 respectively. The default condition, if not specified, after power on or delivery, should default to 12:00 PM or 00:00. Depending upon the market set, the clock will default to either 12 or 24 hour format.
The time format is adjusted from the TS. Under conditions when any bus system could be asleep or shut down, the TS does not allow clock adjustments.
