Replaced battery - everything is still programmed...?

Recommended Posts

I apologize in advance if this is the wrong forum (mods feel free to move it!).

 

So I've been getting the dreaded "Check Charging System" light on my 2011 Edge. After MUCH research, I figured the first thing I would do is change out the battery. Funny enough, the old battery wasn't the "right" size so when I realized that I thought FOR SURE this would be the reason! Nope! Lolz..... Anyway, I changed out the battery and did the normal procedure of letting the car warm up to temp, turn on AC, let idle, drive etc to the T. Here's where I'm perplexed, the first thing I noticed when I turned the car on was that all my radio stations were still programmed and the clock was set to the correct time! I took it down to my local O'Reilly's and had them check the charging system and everything came back normal. My first thought is that my PCM is bad only because how else would the car recognize/have stored the radio and clock after removing the battery and putting a new one in? I have no issues getting my hands dirty and can replace the alternator myself, but if the scan came back fine at O'Reilly's, then I would think one would rule out that the alternator is bad, no?

 

Any thoughts on this?

That's normal. The radio presets don't get erased with a battery replacement. The clock gets set from the GPS system, even if your Edge doesn't have Navigation.

Right on. 
 

What are your thoughts on the CCS light still on and when the charging system was tested it came back normal? Could it be a bad PCM?

I assume CCS is for "Check Charging System"? These newer Alternators aren't like old models. They don't change on a contimuos basis. See the videos in MACT's channel (link). Also, @WWWPerfA_ZN0W will give you a much better answer than I could ever do.
