ECCS Parts Handling

NOTE:If a battery terminal is disconnected, the memory will return to the Engine Control Module value. The Electronic Concentrated Engine Control System will now start to self-control at its initial value. Engine operation can vary slightly when the terminal is disconnected. However, this is not an indication of a problem. Do not replace parts because of a slight variation.
