Network Communication

The following adaptive cruise control system components communicate via the HS-CAN:

C-CM
PCM
ABS module
IPC

NOTE: While there are numerous messages internal to the adaptive cruise control system module, the following messages are utilized by the adaptive cruise control system in conjunction with outside systems.
