Body Control System Description and Operation: Notes

The body control system consists of 3 modules and their associated electrical controls. These modules are as follows:

• The dash integration module (DIM).
• The instrument panel integration module (IPM).
• The rear integration module (RIM).

Each module integrates input and output controls for many functional areas. The inputs and outputs are wired to the closest module to minimize the length and amount of the wiring used. All 3 modules communicate on the class 2 serial data circuit, allowing data to be shared among them, as well as with other class 2 modules on the vehicle as needed.
