Greetings, is erasing the error codes using a scanner the same as re-programming the ECM? Haynes Repair Manual says to use a plug in memory saving device so that defaults values in the ECM memory will not be lost.
I cleaned the battery posts with out using a memory saver and now CEL is on and when I do a systems check with hand scanner I have many incompletes. Is there away to reprogram default values or is it dealer issue? Has anyone had same problem? :confused:

I've disconnected my battery several times without any problems. I've never heard of a memory saver. i disconnect it overnight about every 2 weeks. My trans (TIP) shifts a lot better after i do it. No CEL afterwards, I just reset my clock and presets for the radio.

Does your radio work? I know some models if you do the battery thing without saving it you have to get an unlock code for the radio to work.
I've never heard of a CEL issue though.
I say drive it for about 50 miles or so, and when the computer learns again it may go away..
