Okaaa, I found out today that the softwear has infact been updated. Are there any other reasons that this may be happening I got a new battery a few weeks ago, and have had it checked out bye 2 different Chevrolet service and Firestone. 1 Chevy said they could'nt find anything wrong and everything checks out ok. The 2nd said it's the "Altenator". Firestone could'nt find anything because the message never came on while they were running tests on it, nor when they drove it.
That is how its been... the message (Service Battery Charging System), comes and goes. It only comes on every now and then, 2 - 3mins at a time. Yesterday it came on 3 different times, and today 0, none.
Any other suggestions would be greatly appreciated
The charging software upgrade had been performed over a year ago.
Might you know if the alternator can cause this message to come on??? Should I have them to upgrade the software again??? All connections have been checked, I don't want to have to go out and get a new Alternator if that isn't the problem.........
My 07 Avalanche same thing. Bought it used 2 years ago and message comes on now and then. When starting, it cranks slow like the battery is weak but it always starts. Also 1200 watt stereo on original battery. Will wait until it dies before I deal with it.
I called up the dealership (Service area) where I purchased my vehicle, told them my problem, asked if there were any recalls for "shorts". She ran the last 8 of my VIN# and said that the only thing that shows up is The "Battery." So I have an appointment to get it taken care of free of charge. Cause, not only do the headlights, and inside lights flicker (Alternator?) but the "Service Battery Charger" on the Information Center has started to pop up more frequently now.
Also, the snowflake button for the A/C occasionally will flash on/off when I attempt to use the Air Conditioning, and just blows hot air. Hoping the compressor isn't about to take a SH*T. Anyone have this problem too, and know how to resolve it? I live in AZ so it doesn't get below 30 degrees in the Spring or Summertime. I saw on other sites, that people mentioned the cold weather would be a factor, but that's not the case in my situation. I hope it's an easy, simple fix.
Gotta go replace a low beam headlight bulb now.
