ABS

Anyone know exactly where they plug in with the Wabco machine to pull ABS data/diagnostics?

On my 05 Allure 470, the Wabco's located in left front stg bay and marked “Wabco.” Go to their website and you'll see instructions how to press a lever to observe and count the light blinks on the unit and interpret them. It’s code for a problem ID. A very precise code that highlights the problem. My case...wheel wobble from a bum repair of a bum job replacing both front wheel bearings at Fountain RV in Lakeland, FL (don’t go here, they’re stupid and crooked). Lucky to be alive.

8Birds has it. When using the lighted toggle switch, make sure that you don't have a lot of light shining on it as you can easily miss one blink and that will really mess you up when looking at the code chart.



No need to ask me how I found this out.

Thanks folks but I know how to see the blink codes on the switch. I'm getting a 3/5 by the way. But this is not what I'm asking. I'm going to take it to professionals and they have a Wabco machine that plugs in to do sophisticated diagnostics. I'm anticipating the first question they're going to ask since it's not a semi truck is where the Wabco ABS diagnostics port is. This is what I'm trying to locate. I know where the brain of the unit is.

Rich,


I'm not exactly sure where they plugged in, but WWWilliams in Tucson read mine a few months ago with no problems. I didn't think to ask where they read it from. If it's not directly at the Wabco brain, I'm guessing it's at the J1939 plug back in the service center. My 2000 Affinity doesn't have the J1939 plug available in the driver's area, but your newer 2002 might.


Mine is getting ABS lights and error codes because the rubberized connector bodies on the modulator valve cables are aging and cracking.


3-5 blink code looks to be too large sensor gap on right rear. Wabco manual attached if you don't already have it.

Thanks Chris. I may end up at W.W. for this problem so I know they know where to plug in if I go there! I thought the manual said 3-5 would be the right rear tag axle. Do you read it as the RR drive axle? I will look it up again.
