Circuit/System Description

The vehicle communications interface module (VCIM) receives information from the cellular and digital radio antenna located on the outside of the vehicle. The cellular and digital radio antenna is connected to the telematics communication interface control module via a shielded coaxial cable. The antenna cable also provides a path for DC current for powering the cellular and digital radio antenna.
