    2006 Audi A6 C6 ABS Fault 01435

    Hello,

    I've been having an intermittent issue with my ABS controller, and I'm hoping someone here can help me make sense of it.

    Most (but not all) of the time that I start my car and begin driving, shortly after I begin my trip, my ABS module will throw out error code 01435 - implausible signal. However, every time I test my brakes, everything works fine. The brake light switch is functioning properly, the brake pressure sensor is reading accurate pressures, etc. I can clear the code, then continue my trip (for as long as I want) with no further issues - cruise control works, I've had the unfortunate pleasure of finding out that the ABS pump still functions, etc. I have also already replaced the brake light switch, just in case, since it was an inexpensive part. "When in doubt, swap it out."

    I've attached a full scan of my car, as well as links to screenshots of some of the measuring block values. The only thing I didn't catch, because I only saw it once and couldn't grab a screenshot before it went away, is for a couple seconds I had a NEGATIVE value for my brake pressure reading while holding down the pedal.

    Does anyone know what is going on? I'm hoping to avoid changing my ABS pump and control module, as that is a rather expensive repair.

    ABS ERROR:

    Nice post.

    Obviously, you've been to the Wiki article for this fault.

    It sure would be nice if Audi provided more details as to what can cause this "Implausible Signal" code. To me it means the value from the brake pressure sensor isn't reasonable given other values the ABS module is seeing at the same time.

    I really wonder about that negative value.. Have you logged Group 9 while driving?

    -Uwe-
    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    My phone ate my first attempted reply...

    This is a Bosch controller, so unfortunately, I cannot log anything while driving. Also of interest, now that I've made a post about it, my car has been behaving itself all day today. Go figure.

    And yes, I live by your wiki when doing diagnostics work. It's a wonderful resource. I always start there, and only go elsewhere if it doesn't have enough/any information. Unfortunately, even "elsewhere" doesn't have anything terribly helpful for this one.

    The sensor is bad, there is a connection issue, ( most likely bad ground since happens cold )contaminated fluid port (doubtful) or faulty ABS module.
    The negative value is when sensor reading went or goes offline.

    Just to clarify and make sure we're on the same page... is that ANY negative value, or just a negative value such as -1? My sensor gave a negative value equivalent to what the actual pressure should be if positive. It was 30-something bar, except negative.

    Unplug it and watch values in blocks or additionally hook up a decade box and watch blocks as you tap out reading's to qualify the circuit.

    I'm afraid you've lost me. There's only a single plug to the ABS controller, so if I unplug it, I can't communicate with it anymore. And what is a decade box?

    Variable resister in this case to put between controller and sensor.
    JPPSG it's in there & Google it.
    Plug to ABS module doesn't mean anything being a single wire, what's the point of your statement?

    The sensor is built into the controller, so I can't put anything between them.

    Single plug means I can't power or communicate with the module if I unplug it, so I also can't try and isolate a single output from it without ruining my wire loom.

    It's sounding like I need to replace the module. Didn't want to, but it is what it is. Thank you both for your assistance.

    Nope...........

    Wire looms can be taken apart without ruining them, time to get proficient?
