    Hello guys,
    Sorry for posting this topic if it is already discussed. I did not find it, may be because I am new here.

    My case is the following.
    I’ve got the 4.6 from 2010 last month.
    It came with ABS, and traction lights on on the dash and ADVANCETRACK SERVICE message.

    When we check the car with ODB2 it came up the following error code C1958 - Dynamic Stability Control Valve Front Left Circuit Fault.

    I have checked here and there and everywhere it says it is a faulty ABS module. So, I’m removed the cool intake and I am about to unscrew the module and send it for repair.

    The questions I have now are can I drive the care after I assemble the parts back without the ABS module?

    Will I have brakes?

    Can I hurt the Brake Pump since it will remain open because of the missing module?

    Can I damage something driving it without a module?

    I have read that is drivable but it is without ABS and traction, but as far as I know it is the same case now with the faulty module.

    So please advice if you had the same case. I want to wait for an opinion before outing the parts back. Or may be will wait the repaired module and then reassemble.

    How do you plan on connecting the brake lines with the abs module removed? You will have 6 brakelines dangling.

    I have not disconnected the brake lines. They are connected to the brake pump.
    I have only disconnected the ABS control module.
    Brake pump and connected lines on pic 1.
    And the removed module on pic 2.

    Is this a common failure for these modules?
    In my past experience, ABS modules tend to fail mechanically.
    I would think a rebuilder would want the entire unit, not just the electrics.

    I think is common. There is a lot of information about it in the net.
    But anyhow I would like to receive an opinion from someone who had the same situation.
    Someone who knows can this car be driven without this module till it’s repaired.

    Not recommended to drive it taken half apart. Given the amount of dirt present wouldn't be surprised that you've already contaminated the contacts. If you don't really know what you're doing do yourself a favor and get a professional to look at it. It may be just end up being something in the left front sensor circuit which on average experiences a lot more abuse compared to the ABS itself.

    Thank you for the opinion.
    I have not driven it since the module was removed.
    It was about to be smart if I cleaned it before removing but...
    Can you suggest what should I use to clean the contacts before putting the contacts back?
    Just in case some dirt got there...

    For what it is worth:
    I recently replaced my ABS module on my 2009 Ford Escape Hybrid using inexpensive tools from Forscan (linked below).
    It's pretty straightforward to replace the entire module with a new one or junkyard one.
    The forscan tool can transfer the configuration (as built data) and perform the bleeding and calibration of the new module.
    The steps are simple once you figure out how forscan works.
    (1) With the old ABS module still connected - use forscan to save off the as built information.
    (2) Install the new ABS module. Use forscan to upload the as built information to the replacement module
    (3) Use forscan to put the ABS module in to bleed configuration.
    (4) Bleed the brakes as you would any car.
    (5) Use forscan to run the ABS calibration procedure.

    Enjoy.

    If you don't transfer the as built information then you will introduce new codes related to VIN number not matching within the ABS controller... or maybe worse. Not sure what all settings are tailored within the module for each car.

    There is a free version and a paid version. I think the free version can perform all of the steps I listed.

    Yes somehow the ABS works all the time for stabilization control and not just when you apply the brakes. The "As Built" data has what type of brakes you have. The 2014 model you have three choices. Brembo, Standard and 6cyl. There might also be a GT500 setting.

    Free trial license is good for two months and can be renewed.
    Paid license never expires.
    No difference in functionality.

    I should point out that the reason I replaced my ABS module was due to a mechanical failure. One of the valves started leaking and resulted in a hydraulic circuit imbalance. The ABS module went in a a fail safe mode where the valves were no longer operating (ABS light on) and no recovery. When this happens the volume of fluid being pushed by the master cylinder is greater than when the ABS is operating normally resulting in a pedal that goes almost all the way to the floor. It's meant to be a 'limp home' condition, not a daily driver condition.

    In my opinion the ABS should be repaired / replaced if it's not working as designed. If your ABS light is on, if the valves are experiencing intermittent failures, then you're probably asking for an un-expected pedal change that might result in a crash.

    Be safe.

    This video covers a different vehicle but goes in to great detail about how the different hydraulic circuits work.
