brake stuff

[ThomasWerner]

has anyone dealt with " service anti lock brakes" yet with a definite fix???
My 2018 dually flashed at me the other day and then disappeared. The weather was very humid and rainy.
Don't know if that makes a difference.
Let me know if any folks had this. By the way , the mileage is only 19,500.!!

Pickup or C&C (as labeled)?

Is the speedo working normally?

 

[ThomasWerner]

Pickup, speedo works ok.

Does working ok mean that it has issues? Or does ok mean it works normally?

 

[ThomasWerner]

ok means working normally to me.

When you tell a mechanic something works “ok” it generally is taken that it’s working, but not normally.

Since it occurred in moisture, and the system is working normally otherwise, I would check the connections at each wheel speed sensor and probably put some dielectric grease on them.

I have a bad wheel sensor that died a few days ago when I had a flat. The sensor stem had a crack and was slowly leaking air . The shop replaced the sensor with a regular valve stem until I could get a replacement form Dodge. I don't understand why that would affect the anti lock system. Weird!

That’s a TPMS sensor and wont affect the anti-lock system. You want to look at the wheel speed sensor connections which are by the front wheel bearings and rear wheel bearings.

OK, I'll check em out .
Will update if I find anything.

ThomasWerner,
I just went through a very similar issue with mine, it would only show up in the morning on first startup when it was cold and very damp outside. I would get a message on the dash "Service electronic braking system" and the ABS light, check engine light and traction control lights would come on then go out after startup and would not appear the rest of the day. But would do it again the next day if it was cold and damp at first startup. The problem was the batteries, changed them and haven't had the issue since. I guess the grid heater was dropping the voltage so low it was causing electrical "gremlins" on cold damp/rainy mornings. All is good now. Hope this helps.

 

[ThomasWerner]

Thanks for the reply. Something to check out also. Will update soon.

Well I guess no one in the whole world ever had this fault code show up other than gsykes. Guess we are the lucky ones . Ha!
If it gets serious I guess I'll head to the dealer and throw em my wallet!
