Ecu power cable fault detection

A process comprising:

• operating an electronic control system including an electronic control unit (ECU) including a housing, a circuit board disposed in the housing, and a power terminal conductively coupled with the circuit board and accessible from an exterior of the housing, and a power cable operatively coupled with the power terminal and one of a power supply and a load, the power cable including a terminal connector mechanically and conductively coupled with a jacketed conductor and conductively coupled with the power terminal, the operating including sensing with a first temperature sensor a first temperature indicative of temperature of the power terminal;
• sensing with a second temperature sensor a second temperature indicative of temperature of an operating environment of the circuit board;
• providing with a diagnostic circuit operatively coupled with the first temperature sensor and the second temperature sensors output indicative of presence or absence of a fault of the power cable in response to a in response to a difference between the first temperature and the second temperature;
• modifying operation of the ECU with a controller in response to the output indicative of presence or absence of a fault of the power cable.
