Intermittant codes...battery?

[SedonaBound]

A few days ago I posted how my battery was sporadically going dead with minimal loads. It seems strong when starting except for these incidents; I've never had any weak battery indication. I'm going to have it checked and replaced if needed next time I get into town. Yesterday, I got a TCS warning light, then a "Service 4WD" and "Stability Off" messages. When I restarted, they were all clear. Today I exercised all the 4WD settings a couple times. The only indicators I got was the TCS light and "Stability System Off" in 4L. The manual isn't clear on the display but I think that's correct. They cleared when I went back to 4H

I suspect the intermittant messages are more symptoms of the battery going bad or maybe the OEM terminals. My Porsche gave random codes when the battery was bad.

i had those messages when i had my 4wd cluster unplugged for a while. i had someone with a snap-on code reader hook it up to my truck. had all kinds of codes relating to the transfer case communication and such. he cleared them all and i havent had any more messages or codes. i was almost ready to buy a new 4wd module on ebay but i finally found this guy through my local 4wd club. did you happen to notice if your indication for the 4wd was lit or not. when i was having these issues, it wouldnt light up so i had no idea if it was in 4hi, lock, unlock, 4lo or what. id restart the truck, itd go away only to have the messages come back a day or so later... id say try and find someone with a code reader and see what it tells you. you can have chassis codes with no cel light.

The messages/TSC light appeared when in normal 4H unlocked. Haven't had any fishy lights in the 4WD buttons.

I have a buddy that has a code reader, I will ask him if he knows what they mean... Btw, I think you can just google the codes on the web and see if it tells you exactly what they are!
