System overview

Control module




The traffic message channel module (TMC) is an option only available in the European market for vehicles with a navigation system. The traffic message channel module (TMC) receives radio transmitted traffic messages.
TMC (Traffic Message Channel) is a standardized code system for traffic messages giving information about road repairs, traffic queues etc.
In S40, the traffic message channel module (TMC) is located on the parcel shelf. In V50, it is located under the right door window.
In C70, the traffic message channel module (TMC) is located behind the right wheel housing.
In C30, the traffic message channel module (TMC) is located behind the right B-post.
The control module uses optical serial communication to communicate with other components on the MOST network. This means that all communication with the control module is via the infotainment control module (ICM).
Any diagnostic trouble codes (DTCs) are stored in the control module memory. This information can be read off using VIDA via the data link connector (DLC) in the vehicle.
For further information, also see Signal specifications.

Signals
The table below summarizes the input signals to and output signals from the traffic message channel module (TMC). The signal types are divided into directly connected signals and MOST communication. The illustration below displays the same information with the Volvo component designations.
