Using latent diagnostic capabilities for additional CAN bus monitoring

A system providing enhanced diagnostic monitoring of operations of an associated work vehicle, the system comprising:

• a Controller Area Network (CAN) bus;
• and
• a first CAN device controlling a first operation of the associated work vehicle, the first CAN device comprising:
• a first processor;
• a first CAN transceiver operatively coupling the first processor with the CAN bus;
• a first memory device;
• first operation control logic stored in the first memory device, the first operation control logic being executable by the first processor to control the first operation of the associated work vehicle based on a first operation command message received by the first CAN device from the CAN bus via the first CAN transceiver;
• first operation status reporting logic stored in the first memory device, the first operation status reporting logic being executable by the first processor to:
• determine, at a first time rate, values of a first operational signal of the first operation;
• generate first signal first operation status CAN messages having a first message priority and comprising first signal first operation data representative of the values of the first operational signal of the first operation determined at the first time rate;
• and
• transmit the first signal first operation status CAN messages via the first CAN transceiver to the CAN bus at the first time rate;
• and
• first operation diagnostic reporting logic stored in the first memory device, the first operation diagnostic reporting logic being selectively executable by the first processor in response to the first CAN device receiving a first enhanced diagnostics command message from the CAN bus to one or more of:
• determine, at a second time rate greater than the first time rate, values of the first operational signal of the first operation;
• generate first signal first operation enhanced status CAN messages comprising first signal first operation enhanced data representative of the values of the first operational signal of the first operation determined at the second time rate;
• and transmit the first signal first operation enhanced status CAN messages via the first CAN transceiver to the CAN bus at the second time rate in lieu of transmitting the first signal first operation status CAN messages to the CAN bus at the first time rate;
• and/or
• determine values of a second operational signal of the first operation different than the first operational signal of the first operation;
• generate second signal first operation status CAN messages having a specified message priority and comprising second signal first operation data representative of the determined values of the second operational signal of the first operation;
• and transmit the second signal first operation status CAN messages via the first CAN transceiver to the CAN bus;
• and/or
• determine, at the first time rate, the values of the first operational signal of the first operation;
• generate first signal first operation status prioritized CAN messages having a second message priority higher than the first message priority and comprising the first signal first operation data representative of the values of the first operational signal of the first operation determined at the first time rate;
• and transmit the first signal first operation status prioritized CAN messages to the CAN bus at the first time rate in lieu of transmitting the first signal first operation status CAN messages to the CAN bus at the first time rate.
