I HAVE 1992 DODEGE CARAVAN AND MY ABS LIGHT TURN ON .. WHAT IS THAT ? OR WHAT CAN I DO

You don't need a diagram to replace all the
brake lines on that vehicle

I had one for 18.5 years and did them
3 times because of rust.

have anti brakeing system checked have code pulled to find problem code will go off after problem is fixed

Yes this is an acceptable quick fix if you can stand the ABS light on. You now have non ABS standard power brakes. Folks survived without ABS for many years. I personally hate ABS systems.

2007 dodge grand caravan: ABS light is on trac is off. What is wrong?

Yes, The light should clear after fix the problem. Check the connection on the sensors. Theres 4, one at each wheel. If you have air in the lines the ABS light will come on. To bleed go left rear, right front, right rear, left front. Don't let the reservoir go dry. Brake fluid should be changed every 30,000 miles

You don't. Check all the wheel speed sensors & make sure they aren't damaged. If not, check the codes & diagnose from there.

Yes it does have abs.

The most common failure of an ABS is wheel sensors. I doubt you'll have to replace the entire system.
