Service tools
Onboard controls
Monitoring systemsThe service tool can send information to the ECM through the Cat Data Link. The ECM can provide information over the Cat Data Link to the following items: other electronic controls and service tool. The information can be for diagnostics, or the information can be used to control other systems on the machine. CAN Data Link
The CAN Data Link is an input and an output of the machine ECM. The CAN Data Link is designed to communicate with other electronic control modules through the machine harness. The CAN Data Link consists of internal ECM circuits and a twisted pair of wires within the wire harness. The CAN Data Link is bidirectional. The CAN Data Link allows the ECM to receive information and the CAN Data Link allows the ECM to send information. The CAN Data Link communicates at a faster rate than the CAT Data Link.
