Abstract
A method is provided for monitoring communications in a machine including electronic control module (ECM) components connected via datalinks. A message is received on a datalink. The source address of the received message is determined. The received message is added to an address list based on the source address, and the address list is evaluated to determine the status of a datalink associated with each ECM component.
Claims16
A method for monitoring communications in a machine including at least one electronic control module (ECM) component connected via at least one datalink, the method comprising:
- receiving a message on a datalink;
- determining a source address of the received message;
- adding the received message to an address list based on the source address;
- and
- evaluating the address list to determine the status of a datalink associated with at least one ECM component.
A system for monitoring communications in a machine including at least one electronic control module (ECM) component connected via at least one datalink, the system comprising:
- an electronic service tool system, wherein the electronic service tool system includes a microprocessor configured to monitor communications in the machine by:
- receiving a message on a datalink;
- determining a source address of the received message;
- adding the received message to an address list based on the source address;
- and
- evaluating the address list to determine the status of a datalink associated with at least one ECM component.
A system for monitoring J1939 communications in a vehicle including electronic control module (ECM) components connected via datalinks, the system comprising:
- a storage device for storing an address list;
- a display device for displaying results of monitoring the communication;
- and
- an electronic service tool system, wherein the electronic service tool system includes a microprocessor configured to monitor J1939 communications in the vehicle by performing the steps of:
- receiving a message on a datalink;
- determining the source address of the received message;
- adding the received message to an address list based on the source address;
- and
- evaluating the address list to determine the status of a datalink associated with one or more ECM component.
