The yellow ABS light will turn on whenever the red brake light is on because the computer assumes it won't be able to perform ABS stops safely. You need to address the red light for the base brake system. That is turned on when the parking brake is not fully released, the brake fluid level is low, or there's a failure in one of the two brake hydraulic systems. If the brake fluid level is low, there's either a leak that must be addressed, or more commonly the front brake pads are worn down and in need of replacement. If you add any brake fluid, be sure it's clean and from a sealed, (tightly-closed) container, but add just enough to turn the light off. Never fill the reservoir because when the front brake pads are replaced, it will result in a lot of brake fluid going back up to the reservoir. You need room for that so it doesn't overflow and make a mess. Also be absolutely certain to not get a hint of petroleum product like engine oil or transmission fluid mixed in with the brake fluid.

I would scan the ABS system as well this video will show you how.

Once the red light is off, you'll likely need to turn the ignition switch off and back on to get the yellow light to turn off.

About 5 minutes after cold cranking my crown the ABS and Brake Lights come on. There is no leaking fluid and the pressure is good. What should I do? It still brakes fine, I am just scared of the lights.

Have you checked the fluid level in the master cylinder? If it's low enough it will turn them on! And it could be as simple as you need a brake job!

You can't test the module you need a scanner which a pro has but if it's leaking the line may have stripped the box.

My battery light and ABS light came on all electrical accessories went out radio turn signal cig lighter etc and the battery gage went to full charge. It boiled the acid from the battery. When it idles the bat light goes out and the gage returns to normal but as soon as the engine revs the bat light comes on and the needle pegs.
Please help

Check fuse no. 2 30 amp in the engine compartment fuse box and fuse no. 15 10amp if both okay -The internal voltage regulator is not controlling field generation of the alternator-double check the wiring from the alternator to the charge indicator
