OK. I was just pulling out of my subdivision and on to the main road when "Charging system failure" popped up for a second and then went away. I went to check the batt. voltage via the DIC and it was over 15v. As i watched it it slowly dropped down to 14.51 and stayed steady. Maybe the voltage regulator freaked out for a second? I dunno, thoughts? Battery is still original, that was on my mind.

mine used to do that. itll come on if the volts are over 15.8. i had the zzp voltage booster tho. took it off and never had the problem since. it got to the point where it would chime 30 times in a 10 minute drive. it drove me crazy. was it cold when it happened?

The outside temp was about 40, and rainy and the engine was cold. It was only running for 1 min or less.

yea that could be why. mine used to go crazy when the car didnt warm up. next time it happens look at the dic and see if its 15.8 or higher. i saw 16.1 one time and almost sh*t myself.

I have the dic on battery and I'll keep an eye on it for a while. I have a feeling it was pretty high, because by the time i switched the dic to battery it was already dropping steadily. i think It was at 15.2 when i looked.

Mine seems unusally low alot. i have seen it around 12V driving down the road.

That is kinda low. If you have a multi-meter check the battery when the car is off and see what the voltage is. it should be above 12V

Ya well a battery should be holding 12.6V at a normal full charge. The baterys have 6 cells producing 2.1v per cell.But the rest of the time its like13.8-14.2V. Sojust get to wait around till something breaks.

Mine did this once a couple months ago on a regular winter day about a couple minutes after starting. It went away and never came back. The dealer checked it out and says nothing shows up as being a problem. These cars have way too much monitoring going on in them. Every other car you've ever owned probably had voltage spikes from time to time but never bitched about it.

Yeah it seems like nothing. I've been keeping an eye on it and its been fine.
