349 and 352 Excavator Systems
ECM's and other components communicate via the "blank"?
Controller Area Network (CAN). This allows each ECM's software to make decisions based on all of the input data from the machine, engine and other systems.
What does "IMU" stand for?
Inertial Measuring Unit, measures angles of implements then communicates over the CAN bus to the machine ecm.
What does "AMR" stand for?
Anisotropic Magneto-Resistive. Type of sensor that consists of a sensor and a magnet. Used to detect a position in relation to another object. Generates PWM signals.
What are connectors called on the ECM?
J1 and J2 connectors.
CAN data link is one directional? True or False.
False. It is bi directional, allowing the machine ecm to both send and recieve info with the engine ecm.
What does "BCM" stand for?
Body Control Module, used to link input and output components to the machine ECM via the Can data link.
What is the connector called on the "BCM"?
J1 Connector.
