Диагностика и ремонт Kia Niro EV. Ошибка P0AA6 - Isolaiton fault.

When diagnosing high-voltage battery insulation faults in electric vehicles, the systematic approach involves disconnecting all high-voltage connectors to isolate the problematic component, measuring insulation resistance at each connection point, and identifying the source of moisture intrusion. In this case, the Kia Niro EV's P0AA6 isolation fault was traced to a cracked connector that allowed water to enter the battery compartment, causing the insulation resistance to drop from the normal 1,000+ kOhm to 400 kOhm. The repair process requires drying the battery for approximately one week, cleaning all rubber seals and connectors, and applying silicone grease to prevent future moisture intrusion. However, manufacturers typically require complete battery replacement when water damage occurs, as the battery modules may have sustained internal damage even if the insulation resistance improves after drying.
