make sure the coolant is exactly the right dexcool with deionized water. The coolant can become a current path otherwise.Hi! I have problem with isolation resistance.
I replaced the battery heater because it was damaged. For 4 months the car was disconnected from the 12V and HV battery. After installing the heater and battery, GDS2 shows 0kohm resistances and errors P1AE6, P1FFF.
The car had software updated a year ago. The battery resistance was measured with a special device and it is OK. What should I check?
