PAN AS-OIL 7E4196 - Caterpillar

Input/Output
Each ECM uses the Cat Data Link to communicate with each other. The data link is bidirectional. The data link allows the ECM to receive information. The data link allows the ECM to send information. The data link allows the sharing of information with other electronic control modules.A module identifier (MID) is assigned to each ECM. The MID for the Brake ECM is the number 116.
