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 and transmit information and the CAN Data Link allows the ECM to send and receive information. The CAN Data Link communicates at a faster rate than the CAT Data Link.The Electronic Key Reader (MSS3i) utilizes CAN data link for flashing.
