COMMUNICATIONS NETWORK

Modules monitor and control vehicle subsystems. A module receives input data from various switches, sensors, etc. and then processes the data to control the subsystem functionality. A module contains on-board diagnostics and provides access to the diagnostic information through a communication network.

Module communication network components:
- message center (optional)
- restraint control module (RCM)
- parking aid module (optional)
- vehicle security module
- anti-lock brake system (ABS) module
- powertrain control module (PCM)
- passive anti-theft system (PATS) module
- 4-wheel drive (4WD) control module
- electronic automatic temperature control (EATC) module
- driver seat (DSM) module
- instrument cluster
