A system and method of detecting an anti-circumvention attempt associated with an ignition interlock device of a vehicle. The method comprises detecting an electrical parameter associated with an electrical power state of the vehicle electrical system that includes the ignition interlock device having at least a relay device and a controller device electrically interconnected within the vehicle electrical system; comparing, responsive to the detecting, the electrical parameter to a threshold condition; inferring an IID circumvention event in accordance with the electrical parameter being one of above and below the threshold condition, and reporting, responsive to the inferring, the IID circumvention event to a central monitoring server computing system.
