WARNING: The first drawback to this operation is that disconnecting the battery will erase all adaptive values in the electronic control module. To re-enter the appropriate adaptive values in the memory of the electronic control module, you need to start a cold engine and drive the car at different speeds and engine speeds for about 20-30 minutes. The engine should also be allowed to idle for about 10 minutes. The second disadvantage is that the radio security codes, clock setting and other values will be erased. They need to be restored after connecting the battery. If possible, use a trouble code reader to clear the trouble codes.
