01hyundai elatr brak lights are stay on and park lights in the front are to but u hit the brakes and the lights go off why is it doing that and why

Do the front park lights work? The front and rear park lights should be on the same circuit. If no park lights operational, possible switch or power/ground issue. If only rear park lights not working, suspect burned out bulbs/wiring problem to rear lights

Make sure the brake light switch is secured in place. If it isn't then you need to be sure the switch bracket is secured in place then adjust the switch.

I have seen in the past a failure of the brake light switch...try unplugging it and by passing it

pull the breck release and kick it at the same time same thing i had to do hey it worked for me

check the bulbs or the sockets for damage
or the wrong bulb
you are getting feedback through the wiring
and that lights up the dash

the problem is the brake lights, repair them and it will come out of park

Do you have a separate parking brake light and a "regular" brake light? Most vehicles only have one light, it illuminates when the parking brake is set, but it also illuminates when the system detects a failure anywhere in the brake system.

You could have a separate light for the anti-lock brake system (ABS ).

Your description of a light that is on till you apply the brakes is usually a sign of some sort of system brake failure. Start with brake fluid level, then inspect the brakes at each wheel, looking for a leak.

If nothing detected there, then you likely have something more serious. (Master brake cyclinder bad, possible something in the ABS brakes, etc.)

Others may disagree, but I would suggest not driving the vehicle (except to a mechanic) until this is corrected.

how do i fix or reset this fault

There is a known failure of the ABS system control board which typically causes this problem. THere are companies out there that will rebuild your current board (if it's rebuildable). Do a search on ABS repair in Moscow, Iowa.

They will rebuild the module for $150.00 and warrant the repair for 5 years (as opposed to up to a $1000 form GM, and no guarantee as to how ling it will last.).

I did this to my '01 Tahoe and am real happy with it. The company offers diagnosis tests to help you determine if the problem is your ABS module.

Reply back what you find.

Pull up on your parking brake pedal and make sure it is fully up, If it isn't it should turn off the light and buzzer, if it doesn't there is a switch located on the mechanism it operates that is bad are needs adjusting. I hope this helps you!
