Body Control System Description And Operation: Notes
WARNING: This page is about a different car, the 2002 Pontiac Bonneville. However, it is still accessible from the selected car via links, so may be relevant.
The body control system consists of the following 3 modules:
- The dash integration module (DIM)
- The instrument panel integration module (IPM)
- The rear integration module (RIM)
Each of the 3 body control modules integrate a number of functional systems under the control of a single module. Each of the modules are connected to the Class 2 serial data line; many control signals are implemented by Class 2 messages.
