ONBOARD DATALINK VOLTAGE MONITORING FOR IMPROVED DIAGNOSTICS

The present disclosure relates to improved diagnostic devices, systems and methods for improving the accuracy and speed of diagnosing datalink/CAN errors on public and private networks within the electronic control systems of machines. The present disclosure includes incorporating one or more diagnostic modules to one or more datalinks within an existing electronic control system. These diagnostic modules can monitor datalink voltages and identify and transmit error messages and datalink voltage anomalies without the need for manual diagnosis by a repair technician. Alternatively, another diagnostic system and method includes installing microchips having datalink voltage measurements to existing modules, such as a telematics module, thereby enabling that the module to identify and report datalink voltage anomalies.
