ABS light on the DIC

[nvme]

About 5 months ago I tried the traction button on the console. I went a few feet forward and backward and nothing happened so i turned it off. Now the ABS and the emergency brake light stays on, the DIC, I think that it is a false notification. I would start the engine and wait until those lights stayed on and the other lights one would go off.and then restart it and the lights would go off. Then about 2 months later it wouldn't work anymore and stayed on, I drive the car about once a week on the freeway for about 20 miles long and some times either brake light would go off or the ABS light would and a few times they both went off. But soon either one or both would come back on in a few minutes. My driveway is a little bit up hill and I can leave in neutral with my foot on the brake petal with the brake light on and release my foot off the petal and the car would roll backwards. So clearly the brake isn't on and the brakes work exactly like they did before. I took it to someone that has a meter for the ABS and everything shows up ok except with the car battery. I took it to Auto Zone and they check it out with their meter and it shows ok. I bought the battery from NAPA on September 2021 and now it is almost 4 years old and it always starts up within 3 or 4 cranks with no foot on the gas petal. Does anyone have any ideals what happened? I intend on driving it that way, I've been told by serval people that even if the ABS doesn't work the regular brakes does, luckily I have never needed the ABS.

I don't know much about ABS but if you know anyone with a Tech2, that could shed some light on the problem. Other then that I would make sure your battery is fully charged and check all your electrical connections and remove and reinstall all the fuses associated with the brake system. Good luck

Go out and find a dirt road with no traffic hit tbe brakes hard at 15-20 mph. If the abs is working it wont slid all the tires the same. The tires should grab, release. repat a dozen times very fast . Ive actually did this on a couple of gm cars that had the abs light on that the dealer said needed a module. After repeating the sudden stop twice abs light is off and all works well. Ps. You want your abs working. One of the best features we have on any car. the car will stop straight on wet slick or icy roads.
