ESC off ON
 

I have a 2007 tucson 2.7 The ABS, ESC are ok but ESC off ON after i


Installed a new front CrossMember and filled brake fluid. What could this be?

Can I have that in English please? I don't understand what you are asking.

Thanks for replaying NovaResource. I have a 2007 Tucson. Last day I was filled my Tucson brake system fluid and the ECS OFF light came on. No matter how many times I pressed the ESC OFF switch, the light never flickered.

First, why were you adding brake fluid? You should only add fluid if needed after changing brake pads. The fulid in the master will drop normally as teh brake pads wear. Never add fluid with worn pads.

Second, I don;t think the brake fluid has anything to do with the ESC. My giess is there is a problem with the ESC or the brake light switch. Does the cruise control work? Do the brake lights work? Has the brake light switch been changed as part of this recall: https://www.hyundaiforum.com/forum/g...e-lights-6251/

I had a vehicle recall fixed on my car about three years ago and stop lamp switch was changed .

Maybe the switch itself is bad. Did you check the fuses for the ESC? It's possible a wheel sensor or tone ring is bad. It needs to be checked out by a trained mechanic.

Thank you so much , i have replaced stop lamp switch by myself and ESC light gone off
