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
