COMPUTER SYSTEM AND COMPUTER-IMPLEMENTED METHOD FOR DETECTING CHANGES IN ISOLATION RESISTANCE IN A FLUID PATH OF A COOLING SYSTEM

Computer system comprising processing circuitry configured to obtain first isolation resistance data associated with an isolation resistance between poles of a vehicle subsystem of a vehicle and a ground connection wherein a fluid path of a cooling system configured to cool the vehicle subsystem is in a first state, obtain second isolation resistance data associated with an isolation resistance between the poles and the ground connection wherein the fluid path is in a second state, where the coolant in the fluid path is electrically energized at least in the second state and determine a change in isolation resistance.
