Entertainment and Comfort Serial Data Line

The Entertainment and Comfort serial data line is an arbitrated communications system similar to class 2. The control modules on the Entertainment and Comfort serial data line can include the following modules:

^ Remote playback device - (CD) changer
The Entertainment and Comfort serial data line is not connected to the Data Link Connector (DLC), so it can not be accessed with a scan tool.
