Some of the modules could be failin--have vehicle scanned and run a data stream to confirm--sensors or acuators may be at issue too

SOURCE: BMW warning lights: BRAKE, ABS and DSC

speedometer prabably stopped working also. ABS module shorted out. Will need to be rebuilt. Go to modulemaster.com. Put in your car info. The site will advise how to diagnose kind of. It will tell you how to remove unit and ship and how to protect the connector and valve body so you can still drive your car. This happened to my 2000 528i so i'm confident this is your problem. When you get the unit back just hook it up and away you go. Lights will go off on thier own right away. Dealer wants over 1000 bucks and will only sell you a new unit. This should be around $350 all said and done.

2003 Chrysler PT Cruiser Base model with no ABS system. I have the trac off, brake and ABS light on.

Question edited for clarity add maker and make some sentences.
Question moved to model category.

My guess is the the new ECU isn't from a base model.

You need an auto electrician with a professional grade scan tool computer. It may be possible to program the ABS and Traction Control out of it. for the Brake Lights issue check that the bulb in the high level brake light is working. That kept me guessing for over a year!

ABS light appeared on dash for a few seconds before going out. What does ABS light mena?

ABS stands for Anti-Lock Braking system. The system could be triggered if you are on wet pavement or sliding and the brakes cannot properly control the vehicle deceleration. The vehicle could also have a fault in the ABS system due to a wheel sensor that is corroded or damaged. This type of problem is best left to an expert as the ABS system can be very expensive to repair.

ABS light

This light can Mean a Few Different Things. It could mean that the Brake Pads are in need of Replacement, The Brake Master Cylinder needs to be Replaced, It could even be Telling you that You were Bracking very Hard Earlier on. Like you would not Know! LOL If it does not go off and the Brake Pedal is ok and it will stop ok, Just Run into a Brake shop and have them take a Quick look and see if these things are OK. Please Rate my Solution, I need all the Help that I can Get! Thanks!

Abs light on as well as brack light on the das

brake pads are the ONLY way to stop you going like 30mph+ when you hit like a wall or person or like another road user & if you do crash YOU will be totally at fault for having an unfit car. The best way to get the lights on your dash to go out is to fit new pads. The lights show that the time when the brakes WILL fail is drawing very near, it is stilll up to you to get the pads changed. You will not get any further warnings from your car prior to not being able to stop at all thus causing endangerment. You will be shocked at just how bad they were when you feel the new pads.

Dash warning light

Do you mean the ABS and BRAKE lights? If so, the ABS module is bad which causes both lights to come on. After rebooting, the module gets tested and the ABS light will come on after a few seconds. If it a module problem the BRAKE light will also come on. The brakes will work normally, but will not provide the anti-lock feature.
