Body Controller: Description and Operation
Body Control Module
OPERATION
There are two Body Control Modules (BCM) for 1993 vehicles: "base" and "premium". The vehicle has a "premium" BCM when it is equipped
with an electronic instrument cluster or EVIC panel monitor. Otherwise, it has a "base" BCM.
The body control module provides power or ground for a variety of systems. It uses a voltage drop to monitor these systems. The body control
module is the only module that has the capability of providing both bias and termination on the CCD bus system.
The premium BCM receives information from the engine node about brake fluid level, engine coolant level, and engine oil level. The BCM is used
to store odometer information displayed in the electronic instrument cluster.
