Dash beeping, ABS / Trac / Brake Failure - What do I need to replace?

[Todd82TA]

Hey guys, sorry to bother you all with this. This is an ongoing problem that I've not been able to deal with. For the past two years, my 2009 Explorer has had a continuous beeping sound. It gives me this error which says "braking system error" and the traction control, ABS, and brake lights are all on.

The car drives fantastic, has low mileage, and looks really, really good...

I've replaced both rear ABS sensors, last year replaced the front passenger wheel hub and sensor, and just last weekend ... I replaced the front drivers side wheel hub (and sensor). When I scan the car's computer, it basically gives me a code that says there is an ABS computer error (I cannot remember exactly what the error is).

So my question is... what left is there to replace? The car drives amazing, like... I can't even tell you. Lots of power, really smooth... it's got maybe 80k miles on it, and I just got all brand new tires two weeks ago. There's nothing mechanically wrong with it. I've verified that all the ABS wires are good ... so I'm kind of at a loss.

If I was going to replace the ABS computer, where is it, and how can I purchase a new one? I did a search for it on eBay and all that comes up is the actual car's ECM. Is the ABS computer integrated into the ECM? I know this isn't the case for many vehicles.


Really appreciate any advice. Thanks!

Ok, so I'm going to bump this... looks like no one ever responded.

I kinda think the 2003-2005 Explorer forums should be matched up with the 2006-2010 Explorers... they're basically the same car if I'm not mistaken?

Anyway, here are some of my error codes I'm getting for the ABS system (see below)...

Ok, these errors are crazy, literally it says that everything is completely wrong with the ABS system. I have 8 error codes. It says everything from low battery voltage, to an inability to read the wheel sensor, or saying that they've failed (for the record, I replaced all of them last year, and replaced the last one about 6 months ago... the front two were included in the wheel hub... so I know they're good.

It says the ECU is failed. Is that more realistically what's going on here? I have no other problems with my car... everything else works.


Thanks!

Check the abs harness and the connectors related.

Check the accelerometer harness as well.

If of the module inputs shortened ,the module wont start

Thank you, I'll check that. I started having this problem a few years ago, and it gradually got worse and worse until such point that it happened all the time. It was temperature sensitive at one point, where I think on cold mornings it would work fine, but on humid and hot days, it would give me issues. I'll check all the connectors.

Do you know where the accelerometer is?


Thanks!
