Zusammenfassung:An apparatus, system, and method are disclosed for detecting cracking in a particulate filter. The method may include providing an apparatus comprising an aftertreatment device with a substrate and a substrate surface, a conductive material forming a conduction path bonded to the surface of the substrate surface, and access points configured to allow a resistance measurement of the conduction path. The method may include measuring the resistance of the conduction path, and determining if one or more cracks have occurred on the substrate surface based on the resistance measurement. The method may further include labeling the degradation level of the aftertreatment device based on the indicated amount of cracking, and replacing the aftertreatment device with an equivalent aftertreatment device, based on the degradation level, after a service event.
