Abstract: A method for determining a two wire open fault on a two wire communications bus including determining a threshold in response to a first data from a first electronic control unit and a second data received from a second electronic control unit via the two wire communications bus, wherein the first data includes a first plurality of dominant bits and a first plurality of recessive bits and the second data includes a second plurality of dominant bits and a second plurality of recessive bits, determining a current network health indicator in response to a third data from the first electronic control unit having a third plurality of dominant bits and a third plurality of recessive bits, and generating a double wire open fault error report in response to the current network health indicator exceeding the threshold.

Abstract: A non-transitory computer-readable medium and methods capable of being executed thereby are provided. The non-transitory computer-readable medium includes contents that are configured to cause a computing system to perform the method related to a charging port of an electrified vehicle. The method, or methods, include taking a current photo of at least one of a charging receptacle or a cordset of the charging port; image processing the current photo; and determining whether the current photo includes one or more identified faults from the image processed current photo. If one or more identified faults are present in the image processed current photo, at least one of: sending a maintenance message; limiting charging; or adjusting system parameters.

Abstract: A vehicle configured to execute one or more methods for detecting function of a charging receptacle during a charging cycle. The methods include supplying a charging current through the pins; monitoring a pin temperature of the pins during the charging current; and applying a first step function to the charging current. The methods may also include monitoring a first step change in the pin temperature during the first step function; comparing the first step change in the pin temperature to a first expected temperature change to create a first deviation; and comparing the first deviation to a predetermined threshold. If the first deviation exceeds the predetermined threshold, signaling a maintenance alert, and if the first deviation is less than the predetermined threshold, logging the first deviation.

Abstract: A system includes a brake torque request module, a brake control module, and a diagnostic module. The brake torque request module is configured to generate a brake torque request based on a brake pedal position during a braking event. The brake control module is configured to apply friction brakes on a wheelset of a vehicle to satisfy the brake torque request during the braking event. The wheelset includes less than all wheels of the vehicle. The diagnostic module is configured to detect a fault in a brake rotor on a wheel in the wheelset based on vehicle operating conditions measured during the braking event.
