Systems and methods are provided for enhancing diagnosis of control logic by automatically triggering latent or quiescent diagnostic logic in response to a CAN bus signal and without requiring a software update of the control logic. The diagnostic logic may be triggered to provide an increase in the frequency of CAN messages that are generated. The diagnostic logic may be further triggered to provide a generation of additional CAN messages reporting operation signals beyond those that are normally generated. The diagnostic logic may be further triggered to provide higher priority to selected CAN messages reporting operation signals. The diagnostic logic may be still further triggered to one or more of increase the frequency of selected CAN report messages, generate additional CAN messages reporting operation signals beyond those that are normally generated, and/or provide higher priority to selected CAN messages reporting operation signals, each without requiring a software update.

Using latent diagnostic capabilities for additional CAN bus monitoring

A work vehicle including a chassis, a ground engaging implement configured to move the chassis along a ground surface, a boom connected to the chassis, an arm connected to the boom, and a bucket connected to the arm. A first actuator rotates the boom with respect to the chassis, second actuator rotates the arm with respect to the boom, and a third actuator rotates the bucket with respect to the arm. A processor calculates a first cycle time of operation of the first actuator, and analyzes if the calculated first cycle time is valid. If the first cycle time is valid, the processor communicates the calculated first cycle time to a user, and if the first cycle time is not valid, the processor repeats the calculation of the first cycle time of operation of the first actuator.
