Network Communication
The following adaptive cruise control system components communicate via the HS-CAN :
- C-CM
- PCM
- ABS module
- Instrument Panel Cluster (IPC)
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:
