1. A method performed in a processor, the method comprising:
detecting an electrical parameter associated with an electrical power state of a vehicle electrical system in a vehicle comprising an ignition interlock device that includes at least a relay device and a controller device electrically interconnected within the vehicle electrical system;
measuring a rate of degradation associated with the electrical parameter of the vehicle electrical system;
comparing the electrical parameter to a threshold condition;
generating an ignition interlock device violation state based on the electrical parameter being one of above and below the threshold condition; and
after generating the ignition interlock device violation state, comparing the rate of degradation of the electrical parameter to a threshold rate;
reversing the ignition interlock device violation state upon determining that the rate of degradation is below the threshold rate; and
maintaining the ignition interlock device violation state upon determining that the rate of degradation is above the threshold rate.
