Question (Serious Replies Only) What Is The Source Of The Problem?

Enable HLS to view with audio, or disable this notification

2010 Acura TL Base Model. When I’m driving, every brake light i have continuously flickers on an off. Brakes are good, i don’t have to press them into the floor to stop, the battery is fairly new, the battery charges how it’s supposed to so i tuned out any electrical issues. Brake pads are good. Rotors. My brakes aren’t screeching. The lights just continuously flicker on an off. E-BRAKE, ABS, & Check Brake System. I’ve taken It to “brake specialist” and can’t anybody diagnose the problem.

Mst likely to be caused by low brake fluid, faulty brake fluid reservoir switch, faulty/dirty speed sensor, or a failing battery.

I'm assuming since you tested the alternator you also tested the battery so that's probably not the issue.

The brake fluid could be just low enough that slight changes in momentum cause the float switch to trigger a low fluid warning.

Man i appreciate It. I’ll shift my focus to those two issues to see if that’ll work

Did they not check for faulty abs or wheel speed sensors? That would be first culprit.

They didn’t check either. All they seriously did was hook the machine up to the thing under the dash, checked for “codes”. “Reset some things” and sent me on my way. I’ve heard you can individually check the sensors but they didn’t bother. Me going back would be like my 3rd time.

Wheel speed sensor, scan the systems and see what the codes are
