ABS Controller?

[Mean_Green]

Hearing an occasional cavitation type noise (buzzing/vibrating) as well as a code turning on the ABS light.

Code reader mentions ABS controller, right front wheel speed sensor and brake switch circuit.

Dealer says no go, out of production and circulation. They have to try and find used or rebuilt.

Not looking to get one right now, but wondering about sources.

Would you list the specific codes that you're getting?

Any opportunity to graph the wheel speed sensors with a scanner?

I'll have to wait to pull them again. Dealer cleared all old codes with a Tech2, so we could see what new ones will post.


I'll look at my HF scanner to see if they're still in memory.

No graphing that I know of.

Common problem is ABS cycling when coming to a stop or at slow speeds. Common cause is worn hubs and or rust under the speed sensor where it mounts. It will set a code for a difference in speed readings at 1 wheel.

Another one, I can see it, but can't get to it. Appears the rotor has to come off at the very least. Then, I'm not sure what.

Thinking about hitting it with BrakeClean in hopes of clearing dust or grime.

Yours is simple, try a 3/4 ton or 1 ton where the rotor doesn't slide off of the hub. I have a pair of front wheel speed sensors for my truck sitting on a shelf where they have been for over 1 year as I keep putting it off because of the PIA it is to change them.
