This is a very common problem with Pacificas. I own one myself, a 2005, and my ABS is almost always on. It came on 3 mths after I bought it, after my warranty ran out. If you research it, it's usually something to do with speed censors going out, or brake sensors. Usually when you have them replaced, they'll go back out again in a months time, and they're costly too! I wish I could just get rid of my car altogether! For now though, I went to www.nhtsa.gov, the National Highway Traffic Administration and sent in a complaint so they can research the problem and possibly put a recall on it, since it's such a popular issue with these cars. If you don't mind, please go and put in your own complaint. Maybe if we get enough of these, they'll recall them, and we won't have to pay for their mistakes in building these cars. Thank you & good luck!
Additional information: I have a 2006 Pacifica with the exact same problem. We were lucky & bought an extended warranty on ours, so we haven't had to pay for the "repairs" to this issue. However, just to let you know, no matter how many sensors or whatnot they've replaced, the problem just keeps coming back over and again. The service manager at the Chrysler dealership told me that the Chrysler engineers are aware of the problem, have no idea what's causing it or how to fix it.
I'm considering demanding Chrysler take the vehicle back. I can't be sure that the brakes/ABS don't have a problem, and I have a long commute to work on busy roads. The dealership said might be worth a try, they don't know if Chrysler has done this in the past (bought back) or not. If I am successful with that, I'll post.
The abs computer detects a malfunction and sets a code.
That is the same as the check engine light. You will need to have the system checked for codes to know possible causes.
Wiring, vacuum line, exhaust restriction.
first thing you do is make sure your not low on anti freeze....keep adding to your over flow container until it doesnt pull it out
The most common cause is the O2 sensor. Most parts houses, O'reilys, Autozome, etc. will read the computer for free in the hope of selling you a part.
Short in the wiring or the lamp holder for the tail light is corroded.
Your belt is either to big or just plain worn out.
Yes, you can not fix it. Just fill the tank every two hundred miles and you will be fine.
Have vehicle scanned to determine the problem

It's not coming on in my car. I keep my car in good repair. ---Update--- It regularly means maintainence required.
