No codes in reader. Anybody had this problem? Dealer said maybe low battery. Disconnected and charged it. Lights still on …
Thanks

Could be a bad wheel speed sensor but I thought they would give a code.

Is it on and stays there all the time?

I am not sure brakleen will do the trick. I think the the wheel speed sensor needs to be replaced with OEM parts. The bad thing is, if that is the problem doesn’t sound like you know which one it is since there isn’t a code.

Danarch is probably correct. The brake clean will most likely do nothing and even if it does, the sensor is probably bad and will not last long.

If you have the J-scan app, you can pull up the wheel speed RPM modules to see which sensor is gone. From that point just replace it. Its only like a 10 dollar part.

Yes, no brake clean, no access. Might give it to dealer after the SEMA show!
Thanks

I was getting the ABS and ECS lights a while back. Only happened after a few hours of driving. Found my rear axle seals leaking pretty bad. Replaced seals and bearings, cleaned everything real good(degreaser soak and a pressure washer) and haven't had a problem since.

Check your cruise control. If it doesn’t work then it is bad wheel speed sensor. A ob2 scanner with abs function should tell u which one it is. Be sure to use a mopar sensor or u will get more practice doing it again

Thanks. Dealer gets like $58 a piece for front of back sensors. Heard auto parts stores and rock auto have them a lot cheaper… someone posted get Mopar products…. FYI
