Method, system, and computer software code for detection and isolation of electrical ground failure and secondary failure

In an off-road vehicle having a resistor grid network and a blower system as part of a braking system operable to determine at least one of a resistor failure and a blower failure, the system including a first series of resistors connected in series, a second series of resistors connected in series, a blower cross to at least one of the first series of resistors and the second series of resistors, a sensor proximate at least one of the first series of resistors, the second series of resistors, and the blower, wherein each individual resistor in the first series connected in parallel to an individual resistor in the second series, and wherein when at least one of a current value, blower speed, and voltage value changes, the grid network is disconnected.
