Abstract
An example operation includes one or more of determining a first output impedance of a first electronic control unit, determining a second output impedance of a second electronic control unit in response to the first output impedance is outside of a range of a first threshold of the first electronic control unit, and notifying in response to a difference between the second output impedance and a second threshold of the second electronic control unit is less than a further difference between the first output impedance and the first threshold.
