Components

The Body Control Module (BCM) controls a number of functional Systems. The BCM is connected to the Class 2 serial data line. Many control signals are implemented via Class 2 messages. The following modules are part of an electrical network connected to the class 2 serial data circuit with exchange information in order to control various subsystems. A description of each of these subsystems is in the appropriate subsection of this service manual.
^ Body control module (BCM)
^ Continuously Variable Road Sensing Suspension Module (CVRSS)
^ Electronic Brake Control Module (EBCM)
^ HVAC control module
^ Electronic Brake Control Module (EBCM)
^ Instrument Panel Cluster (IPC)
^ HVAC Control Processor
^ Powertrain Control Module (PCM)
^ Radio
^ Remote Control Door Lock Receiver (RCDLR)
^ Inflatable Restraint Sensing and Diagnostic Module (SDM)
^ Vehicle Interface Unit (VIU)
