Clock: Description and Operation

CLOCK

The radio sends current time to the instrument panel cluster (IPC) via class 2. The IPC receives a class 2 message from the radio indicating the time. The
IPC analog clock, if equipped, zeroes itself to 12:00 during key up and then resets to the current time via the class 2 message received from the radio.
